• Lenovo S10 Ideapad will not boot while original hard drive is installed, neither from hard drive or

  - by aki

  Hello, first time posting here so I'll try to be very clear. I have a Lenovo S10 Ideapad netbook which fails to boot to an OS. It shows the Lenovo splash screen and can get to the BIOS but it doesn't get to GRUB (was dual booting Ubuntu 9.10 and Win 7, was working fine for months, ie this isn't a new dual boot gone bad). After the splash screen it displays a flashing cursor in the upper left corner. Power cycled to no avail. Here is what I have done trying to narrow the problem down: The machine will boot to Ubuntu using an install/live USB drive, but only if ANOTHER hard drive is installed or NO hard drive is installed. The boot order always lists USB first. Also, there is a 2 gb RAM upgrade but I think that's fine; the Ubuntu USB drive boots fine with it, and "free" sees the whole 2gb of memory. So it seems like the hard drive is bad. I was able to put the bad drive in a different laptop and mount it to recover files. I'm ready to replace the bad hard drive, but I would like to know if this situation makes any sense. If the hard drive is bad, shouldn't I still be able to boot with the Ubuntu USB drive while the bad drive is installed? I would have expected the machine to boot into Ubuntu anyway even if with a bad drive, since the boot order lists USB first. But it seems that when the bad drive is installed, the machine ignores the USB drive and hangs with the flashing cursor. Thanks for any ideas! Sorry for the long post, I just want to put all the info I have up front! Basically I'm going to buy a new drive, but I am mostly curious if this is a typical or at least not unusual situation.

• SSD causing 100% CPU usage in Apache/PHP

  - by Tim Reynolds

  I wanted to increase the performance on my development laptop so I added an Intel 320 Series SSD as my primary drive. Everything is amazingly fast, as expected, except Apache/PHP. I develop Magento by using an Ubuntu 10.10 virtual machine. Information: Host OS: Win 7 Professional 64bit Guest OS: Ubuntu 10.10 32bit Processor: i7 Chipset QM55 SSD: Intel 320 Series 160gb 30% full HDD: Hitachi 320gb 50% full (in side bay using an adapter) Laptop: Lenovo T510 Using: Shared folders Apache Version: 2.2.16 PHP Version: 5.3.3-1 APC Version: 3.1.3p1 APC Memory: 128M Using tmpfs for cache, log, session directories in Magento In the VM running on the SSD (VM files and source files are on the same drive) loading a product page in the Admin takes on average 26.2 seconds and uses 100% CPU for nearly the entire time. In the VM running on the old HDD loading the same page takes on average 4.4 seconds. It mostly uses around 40-50% of the CPU while rendering the page. I have read this post: Performance issues when using SSD for a developer notebook (WAMP/LAMP stack)? It says to change some settings in the bios. I have turned any and all power management features off in the bios. I can't for the life of me understand why this would be happening.

• Wireless to Wireless Transfer Slow on a Linksys WRT54GL

  - by Kyle Brandt

  The Situation: When I try to transfer a file from one computer to another that are both connected via wireless on a WRT54GL (in a office) with dd-wrt firmware I often get bad speeds. In generally they average around 100 kilobytes a second. Either computer can download via wireless from the Internet at at about 2 megabytes a second. The speed is slow with the transfer of one large file. There are about 20 other wireless networks that the computers can see, so there is a lot of noise, but I don't have the equipment to really monitor the frequencies well. But that still seems pretty slow. I thought maybe it was the transmit on each card, but even when they are 5 feet away with a line of sight I still get these speeds. According to Linux both cards are operating at 54g. My Questions: Is this normal for this sort of consumer level wireless equipment? Anything I can do to improve it? why is wireless to wireless transfer slow when everything else isn't? Whats steps might I take to figure out what is happening? For example, are lots of packets not making to the access point requiring retransmissions? Above all, I want to find out what the problem actually is. This may seem odd, but at this point I am more interested in understanding what the problem is than fixing it. What I have tried: I have tried messing with lots of settings. Different channels, xmit power, G-Only, none of which has made anything any better. I've also tried upgrading to newer dd-wrt firmware version and doing a reset to wipe out the settings.

• Windows memory logged on vs logged off

  - by Adi

  Let's say I power on my fresh installed Windows 7 x64 machine. After Windows boots up, there are a bunch of services being started in the background that start allocating memory. Then I enter my user/pass and Windows logs me in. Let's supose I don't do anythig else (I don't explicitely start any application) and I don't have any other app installed by me. So it's fresh install of my machine. My question is: how much memory is needed for all the UI & other stuff? Is it a good indicator to look into task manager and check all the processes started under my user name and sum up all the memory consumed by those processes to get the total amount of memory I am consuming just to stay logged on? Basically this is my question: how much memory is needed just to stay logged on? Now, if log off would all the memory be released back to the system so that the background services can benefit of? Also, I assume that there might be a different discussion for each Windows flavors (?)

• Wastage of resources in Virtualization

  - by Sabeen Malik

  I have asked this question on SO, but was suggested that i ask it here on SF, so here it goes. http://stackoverflow.com/questions/3010753/wastage-of-resources-in-virtualization I am not sure if this is the right place to ask the question. However i hope it is. When looking for a VPS earlier today, I was trying to understand how each container would work in the background. Keeping in mind the fact that the operating system uses most of the memory and power on a system, wouldn't having multiple operating systems in the same machine mean more wastage of resources. For instance if i was running centOS on a dedicated box and it was running lets say 20 background OS level processes. Then i go and install a virtualization platform and install 5 more centOS virtual machines in the same system which are exactly the same as the host operating system. Doesn't this mean duplication of those 20 processes 6 times? So internally the context switching is happening between 120 processes instead of 20? Further Notes: Here is an example of what i am thinking: I have a master-slave configuration for a long running, cpu + memory intensive process, which can be distributed to 4 machines. Lets say when the process runs on these 4 machines with lets say 1 Gh CPU and 1 Gig RAM, i get 400 results per hour from the cluster (assuming 100 results from one machine) . Now i get a bigger machine ( lets say 4Gh and 4 Gig RAM), have 4 virtual hosts on it with 1 Gz CPU and 1 Gig RAM. Will this configuration give me the same 4 results per hour from these 4 virtual hosts?

• Dell Studio 1555 not starting up

  - by Abhishek

  This is a 3-year-old laptop. I never had a big problem with it until now. I updated Kubuntu the night before yesterday. And Firefox got updated to version 18 and a few other related packages got updated. Then I shut down the laptop and restarted it, but it failed to start. I could hear the fan and the hard disk and the optical disk drive initialize. And the power button also lighted up. But there was no video - no POST or BIOS menu. I even opened the laptop up to the point when only the motherboard was the only thing attached to the base cover. I took it to the technician this evening. He checked it casually, and said that it might be a motherboard problem and will cost quite a bit to fix. Though he was not sure and said that he will give me a call after confirming the problem. Has anyone else had the same problem? What was it and what was the fix?

• Laptop shuts down randomly without warning

  - by Robert P.

  My Asus Zenbook UX32V turns off randomly when I'm working on it. This happens both when the computer is recently turned on (5 minutes), and after being on for several days. I'm not running any heavy software The laptop is not heating The fan is not working on the maximum capacity (it's not heating) It happens when the laptop is lying still on the table It is no warning, it simply goes black It happens both when charging and on battery My guess is that it suddenly lose power somehow. What puzzles me is that I can flip the laptop upside down, sideways, shake it, etc. without it shutting off. This makes me think it's not something that's loose causing occasional short-circuits. I realize that the laptop probably doesn't like flipping and shaking, but it was the best way I could troubleshoot. I rarely turn the computer off, only have it in hibernate or sleep mode (most often hibernate). I've never experienced that the laptop is off when I wake it up from sleep mode. I've had the problem for a few months and it happens 2-8 times a week. Specs: Asus Zenbook UX32V Windows 8.1 (it happened in Windows 8.0 too) Intel i5-3317U CPU @ 1.70GHz The laptop is approx 1.5 years, but it has a small dent on one of the sides that probably voids the warranty. The dent has been there since week one and I don't think it's related to the problems I'm having now. Does anyone have a clue what might cause this, and how it might be fixed? I've read all other questions (some of which are listed below) that seem related to my issue, but none report the same behavior as I'm experiencing. Most report heavy games, heating etc. Asus N53J Laptop randomly shuts down Laptop is randomly shutting off Computer shuts down without warning My laptop acer aspire 5720 suddenly turn off randomly Computer randomly shutting down Windows 8.1 randomly shuts self down ASUS K55VM Laptop unexpectedly shuts down

• Looking for comprehensive computer monitoring software

  - by cornjuliox

  Summer in this country is insanely hot. So hot in fact, that I think we just lost a machine due to overheating (last recorded CPU/GPU temp was close to 100 C, now it wont start and lets out a long series of short beeps on power up), but that's not my concern here. Since heat is such a problem for me, I use several different pieces of software to monitor temperatures in my machine. I use MSI Afterburner to monitor GPU temp, control GPU fan speed and for some light overclocking, and then I use Speccy and SpeedFan to monitor the rest of the system, CPU temp and everything. The setup works fine for now, but I want to consolidate all this into one program so I'm not juggling several windows at once. Is there any program out there that will let me monitor the following from a single window: CPU Temp and Fan Speed CPU clock GPU Temp and Fan Speed GPU clock, both core and memory Additionally, mobo temp (Speccy lists both CPU and Motherboard temp, I assume that the latter is referring to North and Southbridge temperatures. I'm also looking for the ability to chart these data points on a graph over time, basically to see just how high the temperatures spike under load and for general analysis. It'd be nice if it could handle overclocking of both CPU and GPU in real time too. Any suggestions? Edit: I forgot to mention that I'm on Windows 7, 64-bit

• How to troubleshoot when one has no idea where to start?

  - by Chris Walton

  I am looking for hints, tips and answers on how to get started on troubleshooting when: The problem is intermittent The problem could lie literally anywhere - operating system; free source software; my own software developments; purchased software; crumbs on the keyboard; the specific combination of software I am currently running; Maxwell's demon; the little blue men actually running the machine have gone on strike; etc. I have expertise only in a few of the areas that are potential candidates for the cause of the problem. The specific problem I am having is detailed below as an example, but I am not seeking answers to my current problem, but rather where and how to start on tackling such problems. I am currently encountering a problem with my new machine. On a few occasions the machine has just frozen; not accepting keystrokes, mouseclicks, or anything except the power on/off switch. Invariably I have been merely browsing the web; I have had a few (<= 6 other applications) running. None of these applications are major; and represent a mix of commercial programs and open source programs, typically migrated from Unix of some variety. My machine is a Windows 7 I7 quad core laptop.

• Hard drive spark, can it be recovered?

  - by user163558

  Alright, so I was going to install Source Film Maker but I didn't have any space, so I decided to connect an HDD via an USB converter(image below). I shut down the machine, turned the PSU off, and connected via a Molex connector & the USB converter. I turned back on the PSU, no sparks or anything, everything normal, but when I turned on the machine, I heard some sizzing(lol?) and sparks flying and a little flame, but the PC was running fine. I pressed the power button instead pulling out the plug (I panicked) so it continued to short circuit for about 10 seconds. There's a very little part on the HDD that become ash, it's near the Molex connector and the circuit is a little black as well. I'm afraid that I will damage the HDD more so I didn't hook up the HDD after all. Do you think it's the PSU(came default with Cooler Master Elite 430, 500W) or it's the HDD(Samsung SP1203N)? P.S: I've attached the HDD same way before(like 3 months ago), and it worked. HDD burn: USB connector: Sorry for the bad image quality, taken with my phone.

• Cheap desktop computer in 19" rack-mountable form-factor?

  - by Alex Basson

  I'm a high school teacher at a small private school. As of this year, we have SMARTBoards in every classroom (though I've had one in the class I share for two years now). The classrooms themselves don't have computers in them, so we teachers bring our laptops to class and connect them to the boards. This has several disadvantages: This takes a few minutes while we wait for the board to boot up and then orient the board to our individual laptop -- we have to do this every time b/c different teachers have different laptops requiring different orientations. This isn't ideal because when you only have 43 minutes per class period, waiting five minutes just to get started is a real waste. Carrying your laptop to class doesn't sound so bad until you consider that we're also carrying textbooks and piles of student papers, and we're carrying it all through crowded high school hallways. More than one laptop has fallen THUNK to the floor, with dire consequences. We feel we could eliminate the need to use our laptops with the SMARTBoards if we had a dedicated computer in each classroom hooked up to the board at all times. Each board set-up is connected to a podium with a standard 19" rack in it, currently housing a power supply and DVD player. There're plenty of rack spaces available. So I'm thinking: maybe we could get some inexpensive computers in a 19" rack-mountable form factor, install them in the podiums, and connect them to the boards on a permanent basis. Any suggestions?

• Troubleshooting: Monitor never turns on, system fans running, DVD-ROM does not open.

  - by Wesley

  Hi all, Here are my specs beforehand: ECS P4VXASD2+ (V5.0) motherboard FSB 533MHz Intel Pentium 4 2.40A GHz Prescott Socket 478 2x 256MB PC2100 DDR RAM, 2x 256MB PC133 SDRAM CoolMax 350W PSU DVD-ROM - will edit with brand & model 128MB ATi Radeon 9800 Pro AGP No hard drive So, I just put those parts together today and I tried to power it up, with the monitor connected to the Radeon 9800 in the AGP slot (mobo does not have VGA port). After turning it on, the CPU fan, graphics fan and system fan go on. However, the monitor remains in standby mode, despite being plugged in. Also, after pushing the button on the DVD-ROM drive, it does not open. I've used the DVD-ROM drive before with absolutely no issues. The graphics card was slightly buggy when I put it on another machine, which was left outside in winter weather for 3 months. (Still that computer's integrated graphics worked fine.) CMOS battery was replaced and jumpers are all set correctly. Now, I'm wondering whether the motherboard, CPU, PSU or GPU is the problem. What can I do to test which part is the problem? Just to clarify, I don't have a hard drive, so I usually boot Ubuntu from the disc drive. Anyways, thanks in advance!

• Using my old PC as a web/file server?

  - by Garrett

  I have an old desktop computer that I've been trying to sell for AGES. I guess nobody is looking for computers because it was advertised at a dirt cheap price on craigslist, local papers, etc. Anyways, I was wondering if it would be worth it to set it up as a home file server, a web dev server (I have a web host for actual production use), and maybe host a few server applications (ex: ventrillo). The computer is actually an old Dell that I cannibalized after the motherboard being destroyed by lightning, so it has fairly new parts in it. The specs are: P4 3.4GHz w/ HT and Artic Cooling Freezer 7 3GB DDR2 533 RAM 80GB hdd (will upgrade the hard drive if it's even worth using as a server) basic dvd rom 430 Watt Thermaltake PSU (it might be important to note that it is only 60% efficiency) ATI Radeon x600 256MB Antec 300 case It's not a really beefy machine, I just can't see giving it away or putting it in the corner to just collect dust. I have Windows Server 2008 R2 Standard and I am confident in my skills in operating most Linux operating systems. I'd also be using it to tinker with when I learn new things in my server admin classes (I'm finishing my 2nd year in college at the moment so I'm still learning) Also, my house is quite old and the electrical wiring is pretty poor (it MIGHT be up to code, then again, where I live most people don't even know what regulations are or let alone know how to spell it...) Would it be safe to leave it running all day and is it going to run up my electric bill because of the PSU efficiency? I only have 5mbit cable internet, but I won't be running very bandwidth intense services on it so it should be ok. I should elaborate on why I am concerned about the power. The circuits should be fine, but I'm more concerned about fire hazard. What is the likelihood that the server could cause an electrical fire? Again, thank you all for the feedback!

• Splitting build cross the network?

  - by Dandikas

  Is there a known solution for splitting build process cross the network machines? Use case: We are an average software development company. We own around 50 development workstations (Quad Core 2.66Ghz, 4 GB ram, 200 GB raid). No need to tell that at any single moment not every machine is loaded to the max. There are 5 to 15 projects running simultaneously at any single moment. Obviously all of them are continuously build on server, than deployed to proper environment. Single project build is taking from 3 to 15 minutes. The problem: Whenever we build 5 projects in a row the last project is going to be ready after around 25 - 50 minutes. Building in parallel does not solve the problem (build is only a part of the game, than you need to deploy, run tests etc.) YES the correct solution is to add another build server, but "That involves buying new Expensive hardware, and we already spent a lot!". Yea, right(damn them)! Anyway. What about splitting build among developers workstation? Lets say whenever we need to build project "A" we check 5 workstations and start build on all that are not overloaded. The build can be canceled by a developer if he really needs all the power of his machine as long as there is at least 1 machine that is still building. After build is finished deployment can be performed to a proper environment (hosted on some server, not on workstation :) ). The bigger the company the more this makes sense to me. Anyone tried something like this? Are there any good practices? Any helpful software?

• Managing disk in a VM

  - by dst

  I'm replacing my two old rack servers with a new one that has plenty of power to take over the functionality my current servers. The server is a 4U rack mount with 16 3.5" SAS drive bays, two 2.5" bays, a Xeon E3-1230v2 CPU and 32GB of ECC RAM. My issue is the following. I would like to have a FreeBSD file server with ZFS managing disks. However, I need other VMs for e.g. a shell/git server, mail server etc. I'm wondering how to deal with the following issues: I want ZFS to fully manage the disks, so I'm not using any hardware RAID. Should I pass the SAS controller directly to the FreeBSD system as passthrough PCI? I want to maximize the reliability of the setup. On what disks should I install the hypervsor and keep server system disks? For (2) I have the option of having a RAID setup on the SAS controller and using that as system disk to store the hypervisor as well as VM images. However, this makes PCI passthrough to the file server impossible. Another option is using the two 2.5" bays. In terms of reliability how are SSDs compared to e.g. WD RE4 disks? Would it make sense to have two SSDs in software RAID as boot disks for the hypervisor or should I just go with e.g. WD RE4 disks in a software RAID setup. I also need to think about where to store the mails for the mail server, but this could be done over NFS between the VMs. BTW, this is for home use, so the load is not really that big. What I'm looking for is best practices for splitting up a server.

• Dell Dimension 8400 Startup error

  - by Michael

  Hello all, thanks first for taking the time to read this and possibly help me...... now I am pretty decent of a computer tech...but not enough. I am having an issue with my computer which is running windows xp and as I mentioned it is a dell Dimension 8400. as soon as I power the system up the fan goes into hyper drive (spins like crazy and is very loud) then the start up screen with dell comes up and the loading bar gets stuck on the process of "Bios Revision A00" and never loads beyound that. I have read alot about it and think that the main problem was that it can not locate the file (which does have an updated version) I think it is A09. I can not enter safe mode, Bios mode or anything. I do have the file on my other computer and I was wondering if there is a way that I can use a usb flash drive (as I have read on other sites) to create a bootable MS-Dos diskette but I am failing at creating as such....is this possible? or is there anything else I can do? I tried to remove the battery from the system for about 10 minutes while it was completely unplug and tried then to reboot it and go into the bios menu but the same thing keeps happening....can anyone help me :-(

• Webapp in Jetty can't find properties file after running a couple days

  - by Cuga

  I have a webapp running in Jetty on Mac OS 10.6. After a few days of it running and without the server losing power or rebooting, it seems to stop working saying it can't find a properties file. This properties file is included inside the .war file deployed to the /webapps directory. If I restart Jetty as the superuser the web service works again just fine. Can anyone lend any advice to what's going on and how I can fix it? The error being shown when it isn't working is: Problem accessing /my-web-service. Reason: INTERNAL_SERVER_ERROR Caused by: java.lang.NullPointerException at com.company.service.Dao.readFromPropertiesFile(BwDao.java:35) at com.company.service.ServletHandler.doGet(ProxyClass.java:66) ... at org.mortbay.jetty.HttpConnection.handle(HttpConnection.java:404) at org.mortbay.io.nio.SelectChannelEndPoint.run(SelectChannelEndPoint.java:410) at org.mortbay.thread.QueuedThreadPool$PoolThread.run(QueuedThreadPool.java:582) Here's where the properties files exist that it's trying to read from the .war file: And this is how the properties are being read from the classpath: Properties properties = new Properties(); properties.load(Thread.currentThread().getContextClassLoader().getResourceAsStream( "app.properties")); Again, this does work just fine if I have just restarted the server, but it seems to fail after running a few days.

• Recover data from physically damaged harddrive. What are my options?

  - by Michael Kniskern

  I was trying to replace the power supply in my desktop PC and ended up physically damaging the data connection from the hard drive to the motherboard. The plastic shelf for the copper prongs on the hard drive broke into the cable. Here is a picture of my handy work: I went to Best Buy Geek Squad to discuss my options and they said that they will need to send it to the recover center it could cost anywhere between $250 to $1600 USD to recover the data out the hard drive Is this reasonable for data recovery from a physically damaged hard drive? Are there any other options I can explore? I am going to talk to the data doctors to see what my options are. Update I took the HD to Data Doctors, and they told me that the SATA connection was broken to they would need to replaced the data connector and then copy the data to a brand new hard drive. So, with the initial analysis, cost of replacement parts, and data recovery fee it came out to $865.00 USD. The technician specifically stated if this was an older hard drive that would just need to replace the data connector. But because there is specific information related to the individual hard drive in the flash ROM, they need to transfer the data to a brand new hard drive.

• If I partition a drive connected via eSata will it show different partitions when connected via USB?

  - by jeffreypriebe

  I have an odd problem with an external drive. I'm formatting it connected to my laptop prior to connecting it to my router. The HDD enclosure has both an eSata and USB connections. Generally, I connect it via eSata to my laptop. I created my partitions and connected it to the router, but I see partition information that is different than what I created. After chasing leads concerning large HDD size, I mindlessly connected the HDD to my laptop with USB. Lo! I see the same partitions as the router. Attached are screenshots using the same program and the HDD in question. The only difference is the connection. For the first, I connected via eSata and hit "refresh" on the partition program. Then, turned off the HDD, disconnected the eSata cable, and connected via USB. Power and refresh. eSata: reports a total HDD size of 2328 GB, with four partitions (the third being 1.96TB) USB: reports a total HDD size of 280 GB, with three partitions (the third being 279 GB) Any idea why this is happening? It looks like it clearly is an issue of the 4K sector size and not playing nice with the USB enclosure. I tried it eSata and USB in Windows and Linux and it appears consistently that eSata is reporting correctly, USB incorrectly.

• Can't get past bootcamp Windows logo, freezes immediately after picking boot partition -- Windows 7

  - by cksubs

  Hi, I had a fine install of Windows 7 alongside Snow Leopard. I had a power outage, and Windows restarted. When I booted via the "Hold Option" sceen, it started hanging at the grayscale "Windows logo" (squares) that comes up after picking the Windows drive from the bootcamp loader (the Windows version of the grayscale Apple logo when OS X loads). I think this happened once before, and installing rEFIt helped. I did that, but it continued to hang at the same point. I finally got fed up with it and erased the Windows partition via Disk Utility. I then reinstalled Windows 7 x64 from DVD to the fresh partition. Seemed fine. Ran Windows Update then restarted. FFFFFFFFF. Hangs in the same place. What can I do? Like I said, I already have rEFIt installed. Booting the Windows 7 install CD results in the same infinite loading error. I don't have a spare Snow Leopard disk handy.

• Finding useful crash-information in Windows 8 Consumer Preview

  - by Lukas Knuth

  I'm currently diving into C# and wanted to play around with the new Metro-styled-applications introduced with Windows 8, so I updated my Windows 7 to Windows 8 Consumer Preview. The problem I'm facing right now is, that the system freezes after 3-5 minutes. It does not take any input from the keyboard or mouse and it does not recover (at least not in less then 10 minutes). Since I have a background in Linux, I'd like to find some information about the cause of the freeze, but I have no idea where to search. I checked the system-logs (under "System Control" - "Management") but they only record that the system was shut down unexpectedly (doe to the face that I held down the power-button to reboot the PC). There is no useful crash-information in there. I don't want to spend hours on randomly reinstalling drivers and doing things that "might help". Isn't there any place I can find some useful information about the freeze? Before you ask: I installed Windows 8 as an updated on my old Windows 7 installation (which worked fine by the way). My hardware fits the minimum requirements (specs can be found here, the MacMini 3,1 model with 2GHz processor). I have updated the graphics-card drivers to the newest Windows 8 drivers from nVidia.

• OC'ing a Sapphire 7950, problems with memory clock

  - by Cliff

  I bought a new rig with sapphire radeon 7950 flex w/ boost. Good scores initially in 3dmark 11, around 7300 stock. Problem is, as soon as i start overclocking, issues arise. the core clock is at 860, but rises to 925 with boost applied in pressured situations. So all the OC tools are showing 925 as base clock for some reason. Ocing the core clock has been no problem though, got up to 1200 pretty stable, but only an incremental increase in 3dmark 11, to 7600 from 7300, which is worrying. The real trouble starts when i start touching the memory clock. As soon as i touch it even by 1 point up to 1251mhz, the performance goes way down. suddenly i score under 5000 graphics in 3dmark11, no matter if its 1251hz or 1500hz. Ive tried adjusting every other parameter, different tools (sapphiretrixx, catalyst, afterburner) all still the same. Tried upping the power, still same. Where is the issue here?

• Server freezes while installing Redhat Enterprise Linux Server 6

  - by eisaacson

  We've tried both the first options Install or upgrade an existing system Install system with basic video driver When trying option #1, it gets to a screen that has a solid cursor about halfway down, then freezes. When trying option #2, it freezes at the point where it says: Waiting for hardware to initialize... Of course, we bought the unsupported version and haven't found anything to help us so far. Here are the specs to the server in the original post: ASUS P8Z68-M Pro LGA 1155 Intel Z68 HDMI SATA 6Gb/s USB 3.0 Micro ATX Intel Motherboard with UEFI BIOS RAIDMAX Reiter ATX-305WBP Black Steel / Plastic ATX Mid Tower Computer Case 450W Power Supply Intel Core i7-2600 Sandy Bridge 3.4GHz (3.8GHz Turbo Boost) LGA 1155 95W Quad-Core Desktop Processor Intel HD Graphics 2000 BX80623I72600 16GB Ram OCZ Agility 3 SSD 120GB From some of the posts out there could the UEFI Bios or the Sandy Bridge processor be a culprit here? We just tried the DVD on a different computer and it got past that point with ease. It's a standard Dell build compared to our custom machine. Could it be having difficulty recognizing drivers? How do we get past that?

• Can I make my PC backup and then sleep on demand with WHS?

  - by Simon

  I really hate the way that WHS backs up at a particular time in the morning. First of all I don't EVER want my computer turning on when I am not there. EVER. I have a Core-i7 laptop which literally could burn the house down quite easily if it were to turn on in a bag. I also don't ever want my PC to sleep unless I tell it to. I don't have hibernation or sleep enabled and this is the only way that WHS will sleep after a backup is complete. I know that Windows 7 has the ability to disable waking up when on battery power but it doesn't seem to work on my laptop. These are the possibilities (with wake timers left as default): 'Wake this computer for backup' ON - it turns on in my bag if i forget to turn it off - and stays on when the backup is complete. 'Wake this computer for backup' OFF - it backs up in the morning, but I need to leave the machine on all night. I say 'Backup Now' and then it backs up immediately. I can turn it off when its done if I'm still awake, but then that backup appears as 'locked' in the console and not 'automatically managed'. What I'd really like to do is : Click 'Backup and Sleep' and then go to bed. It will backup immediately and then sleep the PC. This backup must be 'automatically managed' and not appear as a 'locked backup' in my console Show me a confirmation that everything was backed up successfully (or not) when I turn it on. Is there any way to achieve this?
