  • UACCEEventLog 301 Filling Event Logs

    - by rjt
    After pushing out clients for the MS Application Compatibility Toolkit on our domain via GPO, UACCEEventLog 301 occurs a few times per second in the event log. Several Thousand per hour. One test i need to do is logon with Administrator to see if these events go away while Admin, but of course that is not a fix. This is only part of the event log entry, but is the most readable and clearly indicates yet another problem with Antivirus software. But still no fix. Originally, i posted this In Words and Bytes, but then edited it to make it much easier to read. LocalMachine\Users do have Read Access to this key. For a test, i added "Domain Users" but there are many more events for other parts of the registry and for Administrators. <XML> <TYPE> UacceRegistryVirtualization </TYPE> <EXENAME>smcgui.exe</EXENAME> <EXEPATH>c:\program files\symantec\symantec endpoint protection </EXEPATH> <APINAME>RegOpenKeyA</APINAME> <REGKEYNAME> HKEY_LOCAL_MACHINE\SOFTWARE \Symantec\Symantec Endpoint Protection\AV\Storages \SymHeurProcessProtection\RealTimeScan\0 </REGKEYNAME> <RESTRICTEDBYACL>FALSE</RESTRICTEDBYACL> <DESIREDACCESS>MAXIMUM_ALLOWED</DESIREDACCESS> <REGVALUENAME></REGVALUENAME> <REGVALUETYPE>0x00000000</REGVALUETYPE> <REGVALUEDATA></REGVALUEDATA> <CURRENTGROUP>Users</CURRENTGROUP> </XML>

  • Switched from DVI to HDMI, possible audio artifacts?

    - by I take Drukqs
    I'm using an ASUS VH236H monitor and an EVGA GeForce 570 GTX both of which are brand new. My monitor has an audio out port for speakers/headphones so I plugged in my headphones and made a random selection from my library when I noticed two things: There are static-like artifacts during "louder" parts of songs. There's what seems to be a volume cap in place. When I crank the volume past 100% in VLC the decibel level does not truly increase but the amount of static does. The cable is not new; I yanked it off of my PS3 when my DVI cable broke. It has been used a good amount on my HDTV and PS3 so I doubt it's a matter of burn-in. I like the way the setup works with an HDMI cable as opposed to DVI because my headphones barely reach my rig whereas I have plenty of slack when they're plugged into my monitor. Thanks in advance for any support. Note: I'm using a high quality HDMI cable from monoprice, AKG K702 headphones, and VLC media player.

  • Steps to deploy a custom routing protocol

    - by user134589
    I'm a Ph.D Student and I'm researching a Service Centric Networking architecture with resourceallocation on a large scale. What I'm looking to do is expand an existing routing protocol like OSPF with extra fields and some new message types that I need for communication between Nodes. I want to manipulate the cost of a network link and I want paths to be calculated like in OSPF V2/v3, but using the cost that my algorithms have calculated. What I have I have the source code of OSPF from Quagga. I am assuming I can edit this code how I want, including packet structures and creating new types. Yes, I am aware it won't be easy but this is a 6 years research project and I am eager to develop something new, to move forward. What I need I would like to know how I can deploy the edited OSPF source files I have (written in C) on any type of server. I have a large testbed environment available with hundreds of virtual nodes and pretty much any OS out there. So if I want to test my extended protocol, how do I make all the nodes in a network use this to communicate? I do not understand what parts of the kernel I need to edit here. I tried searching for days now and I am unable to find how to deploy a non-existing routing protocol, without the use of an application-level framework. If somebody could push me in the right direction that'd be awesome. note: I need this to be a routingprotocol and not an application, since I want this to work on op of the network layer for performance reasons. Thanks!

  • Power supply switch like stays off motherboard light turns on

    - by Sion
    I bought a computer at the thrift store yesterday. The computer powered on without any error beeps. Getting it back to the house determined that the CD and hard drive needed to be changed. Put in a populated hard drive to check, the computer turned on and seemed to function. Put in a new CD drive, and just put in a new Hard drive. I plugged it in to check and I noticed that the light for the power supply switch did not come on. But I did notice that the light on the motherboard is lit. and I could not turn the computer on. To help troubleshoot it I unplugged the CD and Hard drive. then re-plugged the power supply and switched it on and off. Nothing changed. Parts: Motherboard: Digital Home PSW DH deluxe Power Supply: FSP-Group FX700-GLN Did I accidentally unplug something while installing the hard drive? Is the Power supply fried somehow?

  • Why does my microwave kill the Wi-Fi?

    - by Ohlin
    Every time I start the microwave in the kitchen, our home Wi-Fi stops working and all devices lose connection with our router! The kitchen and the Wi-Fi router are in opposite ends of the apartment but devices are being used a little here and there. We've been annoyed by the instability of the Wi-Fi for some time and it wasn't until recently we realized it was correlated to microwave usage. After some testing with having the microwave on and off we could narrow down the problem to only occurring when the router is in b/g/n mode and uses a set channel. If I change to b/g mode or set channel to auto then there is no problem any more...but still! The router is a Zyxel P-661HNU ("802.11n Wireless ADSL2+ 4-port Security Gateway" with latest firmware) and the microwave is made by Neff with an effect of 1000W (if this information might be useful to anyone). There is an "internet connection" light on the router and it doesn't go out when the interruption occurs so I think this is only an internal Wi-Fi issue. Now to my questions: What parts of the Wi-Fi can possibly be affected by the microwave usage? Frequency? Disturbances in the electrical system? How can setting Auto on channels make a difference? I thought the different channels were just some kind of separation system within the same frequency spectrum? Could this be a sign that the microwave is malfunctioning and slowly roasting us all at home? Is there any need to be worried? Since we were able to find router settings that cooperate well with our microwave's demand for attention, this question is mainly out of curiosity. But as most people out there...I just can't help the fact that I need to know how it's possible :-)

  • Advice on Computer Specs for overall development/general use machine

    - by Ender
    At the moment I am restricted to a laptop with 512MB of RAM, a 120GB HDD and a 1.5GHz Intel processor for all my development and general browsing needs, and as you can probably tell using it for anything modern is a painful experience. As a result I've decided to buy myself a new desktop computer, one that will stand the test of time and one that can be upgraded easily. Rather than build the machine myself I've decided to go through Dell as I've had good experiences with them when purchasing computers for my family. I've had my eye on this as it's got a good amount of RAM, has a decent-rated processor and isn't priced too badly. http://www1.euro.dell.com/uk/en/home/Desktops/inspiron-580/pd.aspx?refid=inspiron-580&s=dhs&cs=ukepp1&~oid=uk~en~20211~inspiron-580_d005827~~ Intel® Core™ i5 Processor 750 (2.66GHz, 8MB) Genuine Windows® 7 Home Premium 64bit - English Display Not Included ATI Radeon™ HD 5450 1GB DDR3 graphics 6144MB Dual Channel DDR3 [3x2048] Memory 1TB (7200rpm) SATA Hard Drive DVD +/- RW Drive (read/write CD & DVD) with DVD Burn software 1 year of coverage included with your PC McAfee® Security Centre - 15 Month Protection - English After the pain of using a slow laptop for all this time the main thing I want is speed. I may look to play a couple of basic games on it, nothing too powerful. Obviously I'll be doing some development on it too so it'll have to be able to handle the latest IDE's and Database tools like SQL Server pretty quickly. Finally, should I ever need to improve it I'd like to be able to add more RAM and change some of the parts. I wouldn't have thought this would be a problem but a few people I've spoken to have said that the amount of RAM the motherboard can handle isn't that great. Is this true? How long can I expect to be using this computer before it's too slow? Thanks in advance for the help.

  • New build won't boot: some fans turning, no beep or video

    - by Dave
    When my new system is powered up, the case fan and power supply fans turn fine. The CPU fan twitches, but never gets going. Although I've heard that with AMDs and Gigabyte motherboards that is not necessary a problem. Hard drive is spinning. However, there is absolutely no indication that anything else is happening. The motherboard, as far as I can tell, does not have an internal speaker, but I harvested one from another machine and plugged it in and still no beeps at all. The monitor screen stays black, on both the integrated VGA and DVI. This is a brand new build, and has never successfully booted. My parts are: AMD Athlon II X2 245 Regor 2.9GHz Socket AM3 65W Dual-Core Processor Model ADX245OCGQBOX - includes CPU cooler) GIGABYTE GA-MA785GPMT-UD2H AM3 AMD 785G HDMI Micro ATX AMD Motherboard - Retail G.SKILL Ripjaws Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666) Desktop Memory Model F3-10666CL8D-4GBRM - Retail CORSAIR CMPSU-400CX 400W ATX12V V2.2 80 PLUS Certified Compatible with Core i7 Power Supply - Retail SAMSUNG Spinpoint F3 HD502HJ 500GB 7200 RPM SATA 3.0Gb/s 3.5" Internal Hard Drive -Bare Drive COOLER MASTER Elite 341 RC-341C-KKN1-GP Black Steel MicroATX Mid Tower Computer Case - Retail I also have a DVD burner, but it acts the same whether that is plugged in or not. I'm using the on board video. What I've tried so far: I've switched power supplies, with no difference. I've tried different monitors (of which all are working on other machines) with no difference. I have tried putting it one memory module at a time, with no difference. I have tried the absolute minimum I can think of (power supply into motherboard, power button ONLY plugged into front panel, CPU fan plugged in), with no difference. I appreciate any ideas anyone might have. Do I need to RMA the motherboard? This is my first build, so there might be something obvious. I was very careful in assembly with static; I'm confident nothing was zapped during assembly.

  • What is the oldest hardware still in production use? How is it kept running?

    - by sleske
    In the spirit of the question What is your oldest hardware that still works?, I'd like to ask: What is the oldest hardware you know that is still in production use? And what challenges did you (or someone else) face in keeping it running (scarce documentation, no support, no spare parts available...)? Most organizations will retire / upgrade software and hardware after 5-10 years, but sometimes old software is kept running on old boxes, because it "just works". I once worked at a client site that was running a critical piece of (in-house developed) business software on a single server running HP-UX. The server was old (ca. 12-13 years), but fortunately still running without problems; however, getting spares would have been very difficult, and since software installation was undocumented, any significant system changes or even new hardware might have caused significant downtime and data loss. We eventually managed to replace it, but this is not always possible. I also read that many organizations still run decade-old mainframe hardware, particularly for highly customized systems controlling industrial machines or power plants. Which old hardware have you encountered? How did you manage these challenges? Related question: http://serverfault.com/questions/82467/should-old-servers-be-retired

  • Faster, secure, protocol/code required for long-distance transfer.

    - by Chopper3
    I've ran into a problem and I'm looking for a new secure protocol/client/server that's faster over a 1Gb/s fibre link - let me tell you the story... I have a pair of redundant, diversely-routed, 1Gb/s links over a distance of around 250 miles or so (not dark fibre but a dedicated point to point link, not a mesh). At the 'client' end I have a HP DL380 G5 (2 x dual-core 2.66Ghz Xeon's, 4GB, Windows 2003EE 32-bit), at the 'server' end I have a HP BL460c G6 (2 x quad-core 2.53Ghz Xeons, 48GB, Oracle Linux 5.3 64-bit). I need to transfer around 500 x 2GB files per week from the client to the server machines per week - but the transfer NEEDS to be secure. Using both iPerf or regular FTP I can get ~80MB/s of transfer pretty consistently, which is great. Using WinSCP or Windows SFTP I can't seem to get more that ~3-4MB/s, at this point the server's CPU is 3% busy while CPU0 of the client goes to ~30% utilised. We've tried editing various TCP window sizes with little success. Both ends are connected to quite low-usage Cisco Cat6509's with Sup720's. I can replace the client machine with a newer machine and/or move it to Linux - but this will take time. Clearly these single-threaded secure Windows clients are introducing too much latency doing their encryption. So a few questions/thoughts; Are there any higher performing secure protocols or client software for Windows that I could try? I'm pretty protocol-gnostic so long as it'll work between Windows and Linux. Should I be using hardware to do the encryption, either in the client or the network parts? If so what would you recommend? I'm not convinced that just swapping the server would be that much faster, the CPU was only at 30% but then again that's higher than I'd have expected given the load - moving to Linux at the client end may be a better idea but would be quite disruptive. Am I missing a trick? Thanks in advance.

  • WAMP Installation - Multiple PHP Version Issues

    - by Pete171
    I have installed WAMP because I am attempting to modify an an application which uses Zend Optimizer (I cannot use Z.O. with PHP5.3+, which is why I decided to install WAMP). I downloaded the latest version - Wamp Server 2.1 - which comes bundled with PHP5.3.5. I then downloaded a PHP version that would be compatible with Z.O. - 5.2.9. - and a compatible Apache version, 2.0.63. My problem: PHP scripts run fine, but anything with MySQL does not work. Running the testmysql.php script returns the fatal error: Fatal error: Call to undefined function mysql_connect() in C:\wamp\www\testmysql.php on line 2". I have looked in the PHP INI files inside both PHP versions, and I'm fairly sure the relevant information is there. At least, there are parts inside that mention MySQL! Perhaps somebody could clarify exactly what information should be present? Also, when visiting a page that called phpinfo(), I noticed that the 'Loaded Configuration File' was pointing to C:\wamp\bin\php\php5.3.5\php.ini, even though I have enabled the older PHP version. I've stopped and started Apache, too, and that hasn't made a difference. Is anybody able to offer any assistance? Anything at all would be great; I'm not very good at messing around with Apache/

  • Will these instructions work when turning of journaling on an ext4 SSD?

    - by snowlord
    I have an Acer Aspire One with an SSD for storage. I recently installed Ubuntu on it and chose ext4 for my filesystem. Then I read that journaling on an SSD isn't the best idea, so I will try to disable journaling and I have found these intstructions (from http://fenidik.blogspot.com/2010/03/ext4-disable-journal.html): # Create ext4 fs on /dev/sda10 disk mkfs.ext4 /dev/sda10 # Enable writeback mode. This mode will typically provide the best ext4 performance. tune2fs -o journal_data_writeback /dev/sda10 # Delete has_journal option tune2fs -O ^has_journal /dev/sda10 # Required fsck e2fsck -f /dev/sda10 # Check fs options dumpe2fs /dev/sda10 |more For more performance add fstab opions: data=writeback,noatime,nodiratime i.e: /dev/sda10 /opt ext4 defaults,data=writeback,noatime,nodiratime 0 0 I will use them on my boot partition. Are there any particularly bad parts here, or are there any missing steps? Will my boot partition be fit for being on an SSD after this? Or should I consider switching to ext2, or even reinstall it all and choose ext2 at partitioning time (I'd rather not though, since I've configured quite some stuff already)?

  • How to add extensions to a lot of files using content of each file?

    - by v8media
    I've got over 10,000 files that don't have extensions from older versions of the Mac OS. They're extremely nested, and they also have all sorts of strange formatting and characters. They don't have file types or creator codes attached to them any longer. A great deal of these files have text in the file that will let me determine extensions (for example Word.Document.8 is in every file created by that version of Word, and Excel.Sheet.8 in every file created with that version of Excel). I found a script that looks like it would work for one of these file types at a time, but it erases parts of filenames after nefarious characters, which is not good. find . -type f -not -name "." -print0 |\ xargs -0 file |\ grep 'Word.Document.8' |\ sed 's/:.*//' |\ xargs -I % echo mv % %.doc So, two questions from that: One is, should I clean the characters in the filenames first, or programmatically deal with those in the script in order to leave them the same? As long as I lose no information from the filenames, I don't see a problem cleaning out slashes and other problem characters. Also, if I clean the filenames, there are likely to be duplicates, so any cleaning script would have to add something like "-1" before the extension to make sure nothing gets lost. 2nd question is how do I change the script so that it will look for more than one file type at the same time and give each the proper extension? I'm not tied to this script, but it is understandable, which is a pro. Mac OS X 10.6 is installed on this file server, but I've got access to any recent versions of OS X. Thanks, Ian

  • Can't install Hyper-V in Windows 8 Pro. Causes boot loop, pain & suffering

    - by Nick
    Hardware: Intel i7 2600K (not overclocked, SLAT compatible, virt. features enabled in bios) Asus Maximus IV Extreme-Z (Z68) 16Gb RAM 256Gb SSD Other non-trivial working parts Adding Hyper-V is causing a boot loop resulting in an attempt at automatic repair by Windows 8 after the second or third loop: I'm trying to get the Windows Phone 8 SDK installed and I've narrowed down my troubles to the Hyper-V feature in Win8. This is required to run the WP8 emulator and there are no install options to omit this feature. My first attempt completely borked the OS as I did not have a recent restore point or system image, so I did a completely clean install and made plenty of backups/restore points. I skipped the SDK install and went straight for the windows feature add-on for Hyper-V. This confirmed that Hyper-V is the issue as the same behavior resulted. I cannot find any hint in the Event Logs. Cancelling automatic recovery causes the same behavior to repeat. I don't have any other VM products installed. My only recourse is to use a restore point, try something else, install it again, and see what happens. No luck so far. I'm on my 10th attempt here. Any help would be much appreciated.

  • Clone Microsoft VM > SharePoint issues

    - by Rob
    Hi, We have an existing (production) Hyper-V VM that I want to clone to create a staging server. This server is NOT on a domain/active-directory - uses all local computer accounts. It is Windows 2008 OS, SharePoint 2007, SQL server 2008, Reporting Services, and some custom line-of-business web-applications. We rename the server etc as per the documentation we have, but are having troubles specifically with SharePoint. Some of the sites do not come up, and some issues adding/updating site settings such as site owners. Does anyone know of a definitive resource to this process? thanks Update: We seem to have most working, but the Shared Service Provider, and the SSP's admin site, are not working. In addition, the custom web-parts that reference IIS Session objects are failing (which seem to be related to the Share Service Provider). All the Windows user accounts for various services are renamed during the server cloning, but the windows account names in SQL server are not automatically changed. We've tried to change them in SQL server but still does not seem to work Seems like allot of work - and am thinking that there must be some guidance out there. also getting this: NullReferenceException: Object reference not set to an instance of an object.] Microsoft.Office.Server.Administration.SqlSessionStateResolver.System.Web. IPartitionResolver.ResolvePartition(Object key) +135

  • Why does apache httpd tell me that my name-based virtualhosts only works with SNI enabled browers (RFC 4366)

    - by Arlukin
    Why does apache give me this error message in my logs? Is it a false positive? [warn] Init: Name-based SSL virtual hosts only work for clients with TLS server name indication support (RFC 4366) I have recently upgraded from Centos 5.7 to 6.3, and by that to a newer httpd version.

  • Force request to miss cache but still store the response

    - by Tom Marthenal
    I have a slow web app that I've placed Varnish in front of. All of the pages are static (they don't vary for a different user), but they need to be updated every 5 minutes so they contain recent data. I have a simple script (wget --mirror) that crawls the entire website every 15 minutes. Each crawl takes about 5 minutes. The point of the crawl is to update every page in the Varnish cache so that a user never has to wait for the page to generate (since all pages have been generated recently thanks to the spider). The timeline looks like this: 00:00:00: Cache flushed 00:00:00: Spider starts crawling to update cache with new pages 00:05:00: Spider finishes crawling, all pages are updated until 1:15 A request that comes in between 0:00:00 and 0:05:00 might hit a page that hasn't been updated yet, and will be forced to wait a few seconds for a response. This isn't acceptable. What I'd like to do is, perhaps using some VCL magic, always foward requests from the spider to the backend, but still store the response in the cache. This way, a user will never have to wait for a page to generate since there is no 5-minute window in which parts of the cache are empty (except perhaps at server startup). How can I do this?

  • nginx codeigniter rewrite: Controller name conflicts with directory

    - by palerdot
    I'm trying out nginx and porting my existing apache configuration to nginx. I have managed to reroute the codeigniter url's successfully, but I'm having a problem with one particular controller whose name coincides with a directory in site root. I managed to make my codeigniter url's work as it did in Apache except that, I have a particular url say http://localhost/hello which coincides with a hello directory in site root. Apache had no problem with this. But nginx routes to this directory instead of the controller. My reroute structure is as follows http://host_name/incoming_url => http://host_name/index.php/incoming_url All the codeigniter files are in site root. My nginx configuration (relevant parts) location / { # First attempt to serve request as file, then # as directory, then fall back to index.html index index.php index.html index.htm; try_files $uri $uri/ /index.php/$request_uri; #apache rewrite rule conversion if (!-e $request_filename){ rewrite ^(.*)/?$ /index.php?/$1 last; } # Uncomment to enable naxsi on this location # include /etc/nginx/naxsi.rules } location ~ \.php.*$ { fastcgi_split_path_info ^(.+\.php)(/.+)$; # NOTE: You should have "cgi.fix_pathinfo = 0;" in php.ini # With php5-cgi alone: fastcgi_pass 127.0.0.1:9000; # With php5-fpm: #fastcgi_pass unix:/var/run/php5-fpm.sock; fastcgi_index index.php; include fastcgi_params; } I'm new to nginx and I need help in figuring out this directory conflict with the Controller name. I figured this configuration from various sources in the web, and any better way of writing my configuration is greatly appreciated.

  • computer fails to boot during/after POST for five or six boots, then works

    - by N13
    For the last few days, my computer has had issues booting. I've seen two different behaviors: The screen displays the graphics card information, then begins to list the RAM, hard drives, etc. At different points in this process (after the graphics info), the computer shuts off. After five or six attempts, it then boots normally. In roughly the same time frame, the computer freezes, and fails to boot. I think it boots successfully on the next attempt. I've also noticed that in some instances, the computer freezes on shutdown. It gets right to the point where it should shut off, but doesn't. I recently combined the best parts of two different machines into this one. I'm booting to GRUB, with Ubuntu 12.04, Linux Mint 11 and Windows Vista (unfortunately) as my OS options. It has an Enermax Modu82+ 525W power supply, and I've used an online calculator to determine that my load shouldn't exceed 400W. I even unplugged a hard drive, but that didn't help. I found the latest BIOS, patched it and checked the settings, but that didn't fix it. I'm fairly certain this issue didn't exist at first, but might have started when the power at my new apartment dropped for a second. The machine is plugged into a surge protector strip, but it's old and I've heard they lose effectiveness with age. Is a power dip as damaging as a spike? If something were damaged, why would it boot successfully after five or six attempts? It's almost like the BIOS or PSU need to be primed. The trouble with debugging is that there seems to be a "grace period" after shutdown where the issue doesn't present itself again. What should I try next?

  • How long will a "safely stored" Solid-State-Drive (SSD) keep its data? (e.g. bank safety-deposit box)

    - by user31575
    Here's my usecase: once-and-only-once copy off photos/videos to an internal SATA Solid State Drive (SSD) put this drive in a well-ventilated, air-conditioned bank "safety deposit box" for safe keeping The question: How long can I safely store a solid-state-drive in such an environment? i.e. 0% bitrot, 100% success when "plugged in" Are some SSD drives more reliable than other for this usecase? (e.g. smaller size vs larger size, SLC vs MLC, different brands, etc) More fodder: I have read that solid state memory cards (e..g compactflash, or sd cards) have much longer durability than other media (DVD's, CD's, hard drives) for this usecase (guaranteed against bitrot/other dysfunction on the order of ~ a decades vs a year ). I don't know if this applies to "SSD hard drives". Copying to one 500Gb ssd vs 8 64gb flash drives is easier SSD SATA hard drives have no moving parts, but they have more "visible electronics" than a compact flash card. I don't know if this "visible electronics" can fail, i.e. in contr I know many will point to carbonite, other cloud backup stuff, but I like the simplicity of having physical copies and wanted to understand the risks/implications thanks,

  • Windows disk change monitoring for malware analysis

    - by SuperDuck
    Not sure if this question belongs to here, because it has some relations with 'serverfault' (system backups) and 'stackoverflow' (software analysis). I'm looking for a solution to monitor disk changes on a Windows system and selectively revert them. It should be able to handle live files like registry parts, so may need to be an offline backup software. It shouldn't silently pass over files which the current admin user doesn't have permissions on (files with no permission entries or owned by the 'system' user) Registry change tracking would be a bonus but is not a requirement I use virtual machines for malware analysis, there is even no solution to list file changes in disk snapshot files (delta VMDK). I currently use Ashampoo for monitoring changes. Though it's the best one between similars, it's not a good software and hasn't really evolved in many 'platinum', 'deluxe' versions released in the last 10 years (it even used non-resizable windows until the latest version). The real problem is it misses some disk / registry changes. Perhaps it only compares modification dates and doesn't catch a change if the dates are preserved. So, I think the solution should compare files using hashes, or file sizes at least. There are numerous backup software out there and I'm sure one can handle this, offline or online.

  • Getting a "CPU over temperature error", but temperatures seem to be normal

    - by Luis Parker
    I built a PC with the following parts: CPU: i5-2500 Motherboard: Asus P8H67-M EVO rev 3.0 RAM: G-Skill Ripjaws Series 8GB (2 x 4GB) DDR3 1333 Video: GTX 560-Ti 1GB I used a crappy (but functioning) old case and a 500W Powercooler supply. The rig also includes 3 HDs and a DVD-RW. Whenever I push the system mildly it resets right away (looks more like power off/power on) and gives me a "CPU over temperature error". However, BIOS always reports <65ºC for the CPU at the moment of the reset, same as Core Temp and RealTemp. This is RealTemp's log since launching BF3 until the reset (just over 1 minute, as you can see) Just to be sure I've checked the CPU cooler and re-applied the thermal paste twice, but nothing changed. I'm not overclocking at all. What am I missing here? Could it be that the old power supply is generating this error? Maybe the mobo isn't reporting temperatures correctly? I don't have a clue on how to troubleshoot this, help Thanks in advance!

  • Computer randomly shuts itself off

    - by Decency
    I have not been able to determine a pattern for why this happens, despite my best efforts. I've attempted to run it on full power with Prime95 and this doesn't trigger a restart. Generally the restarts occur while I'm playing games, watching videos, or even just having multiple tabs open in a browser. However, I often play processor intense games for hours without any restarts occurring, and sometimes they'll happen 3-4 times in an hour during less intense activity, so I don't think that is the problem. I imagine it has something to do with overheating or power consumption so I've been monitoring CPU temperature and cleaning with compressed air, but the problem keeps happening. I don't know how to track power consumption, and assume that this is the problem. Whenever this occurs, the sound gets stuck in a short loop of whatever was playing at the time, though restarts also occur when nothing is playing. Here is a screenshot of temperatures: and under load: Here's the parts list: http://secure.newegg.com/WishList/PublicWishDetail.aspx?WishListNumber=10546754 As shown in the list, the case includes a 585W Power Supply, which I've been told should be plenty. I built the computer myself with a friend's guidance but it's very possible I did something wrong. Right now I'm looking into ensuring that I have the latest drivers for all components. Any help would be appreciated- thanks.

  • Notebook display problem (multiplication)

    - by SubniC
    Hi, I'm having some troubles with the display of a LG E500 notebook. The thing is that without any known reason the display starts to show the screen divided in eigth parts and each part show the display image as if I had a matrix of eigth displays :) I thought it could be some kind of refresh rate problem or driver related, but it is happening at boot-up as well and the BIOS. I got the computer completely unassambled yesterday and I check all the wires and connectors looking for something broken or unconected, but without luck... You can see a picture here of the problem (sorry for the low quality, but I think it illustrate the problem. EDIT 1: I uploaded a new pictrue, here you cans ee the problem better :) There are three horizontal lines that you can see just between the windows. You can see the grey line at the first moment you turn on the computer and the after the duplicated screens show up just like if they where arranged over a grid (over the horizontal lines...) I hope it makes any sense. Do you know what could be happening? or can you tell me what would you do? Thank you very much for your help.

  • Server Hosting + AWS

    - by ledy
    Since my dedicated servers are hosted at a "normal" hosting service, I wonder if there is a really cheap way to extend the server farm with AWS instances. E.g. it seems to be a effient and flexible solution with data storage and ressources for ocassional data processing, too. However, it might be very in-efficient to mix two data centres and transfering data from current webhoster to amazon and vice-versa. In my case, the traffic for this continuous data exchange seems to be expensive and the delay for moving the data back to the hoster leads into a lack or delay. How are best practises for mixing non-aws and aws systems? E.g.: How to move the hosters data to aws as log file storage to run urchin analysis and/or port the log file data into a bigtable for exhausting analysis there. After working with the data: how to bring it back to the hoster and use the data with the webservers there? I am not going to move all the server farm to amazon, only "separate" parts or tasks if the transfer/exchange does not lead to increased cost.

  • Blocking of certain file downloads

    - by Philip Fourie
    I have a problem where I cannot completely download a certain file from a server. The file is 1.9MB in size but only 68% is downloaded and then it hangs. I tried and these cases, which failed: Downloaded the file with HTTP Downloaded the file with FTP Moved the file to different FTP and web servers behind the ISA firewall Tried with IIS 6.0 & IIS 7.0 Multiple download clients. Which included FireFox, FileZilla (on Windows) and wget (on Linux) This worked: Downloading other files from the same location on the server. Both bigger and smaller and in size than the original. FTP and HTTP worked. Earlier version of this file (.DLL) works. It is as if the content of this file has an influence on this file being served. Network architecture: Client Machine - Internet (ISP) - ISA Server - IIS 7.0 The only constants are the ISP, Cisco router and the ISA server. Is it possible that something is rejecting the download because of the contents of the file? I am hoping ISA is the culprit... I am not a ISA expert is there somewhere I can look to establish if it is indeed ISA causing this? Update: Splitting the file into two parts with a hex editor results in one half of the file being served correctly and the other part not. Zipping the file results in the file being downloaded successfully. However this is not an option for this particular scenario. Renaming the file and its extension also doesn't work. Update 2009/10/22: It does NOT seems to be ISA that is causing this problem. We connected a laptop (running IIS) on an available public IP and still the file download to 68% before it hanged. The two remaining components are the ISP and the Cisco 800 series router. Anyone knows about an issue on the router perhaps?
