• Tracking down random BSOD on windows 7

  - by pehrs

  I have gotten a computer running windows 7 handed to me that randomly, several times a day, bsods with a PAGE_FAULT_IN_NONPAGED_AREA (50) or WHEA_UNCORRECTABLE_ERROR (124). Crashes happens regardless of load. I am running out of ideas for how to track this down. Analyzing the minidumps shows the crash to be in ntkrnlmp.exe/WMIADAP.exe System has plenty of power (600w) Ram checks out fine using memtest86+ over a weekend. System is clean inside. No dust build up. Temperatures stay low. As far as I know (and reliability history shows) no new drivers were installed for several months before the problems started. All drivers are now up to date. sfc /scannow reports the system as clean. CHKDSK reports the disks as clean Removing the AV (Avast) has no effect. Any more things that should be tried on windows 7 before I start replacing the hardware?

• Currently well suited SATA2-SSDs for Laptop usage

  - by danilo

  I am looking for a solid state drive for my laptop. My dillemma: I have been waiting for the new Intel SSDs since Q3/2010, as I've heard they should be better and cheaper, due to lower memory manufacturing costs. Now it looks like the new Intel drives are very fast, but still expensive. I would still buy one of them if I could benefit from the full speed. My hardware only has a SATA-2 port though. Thus, my question: Is it worthwhile to buy one of those new Intel SSDs made for SATA-3 if I won't be able to use the full speed? Are there any other promising new SSDs that will be released soon? (Inside the next 1-2 months) If I wouldn't make a good deal buying the newer, faster drives, what drives can you recommend? I don't consider this question subjective, as I am mainly looking for answers concerning the SATA-2/SATA-3 conflict.

• For Loop counting from 1 to n in a windows bat script

  - by raoulsson

  I need to run a windows command n times within a bat script file. I know how to do this in various programming languages but cannot manage to get it right on the windows command line :-( I would expect something like either for(int i = 0; i < 100; i++) { // do something } or even this (though not entirely seriously) 1.upto(100, { // do something }) Thanks! EDIT I can write a program in java, perl, c or whatever that will generate a bat script that looks like this for %%N in (1 2 3 4 5 6 7 8 9 10 11 12) do echo %%N and so on. Or even "better": echo 1 echo 2 echo 3 echo 4 echo 5 echo 6 echo 7 echo 8 echo 9 echo 10 echo 11 echo 12 and then execute it... But the thing is that I need a concise way to specify a range of numbers to iterate through within the script. Thanks!

• Having Troubles Getting My Apache Server Online(NodeJS and Apache)

  - by Jeff Armingol

  I am new here. This is my situation. I am using nodejs modules, serialport2 and socket.io, because I am trying to forward the data from my arduino hardware through serialports. In my server side script, I read the data then forward it to the client side. Now I am using Apache to serve the html page,which is the client side. I am running Nodejs on port 8000 and Apache on port 80. It is running OKAY when I view it in my browser typing localhost:80. The data is appearing and seems fine. Now when I tried to get my Apache server online using a Free DDNS provider(http://www.noip.com/) and my port80, it loaded the webpage but there are no data appearing on the page. What seems to be the problem here? Really need your expertise and advice. Thanks in advanced!

• The security database on the server does not have a computer account for this workstation trust relationship

  - by alex

  I have a Server 2008 machine called OTTO I recently, by mistake, booted up an old machine, also called OTTO (the hardware was unstable, so the new one was set up to take it's place) I shut down the old machine, turned it off, and recycled it (it won't ever be back on) Now, whenever i try to log in to the real OTTO with the domain account (mydomain\Administrator) i get the following error: The security database on the server does not have a computer account for this workstation What can I do to fix this? It doesn't appear in active directory any more I've added it, but I'm guessing this had no effect, due to a different SID I can log in as the local administrator however

• Is it possible to add an existing Azure VM to an Azure Virtual Network?

  - by Dan Harris

  Didn't think this was directly related to programming, so thought Superuser would be better than Stack Overflow.... Is it possible to add an existing Azure VM to an Azure Virtual Network if you didn't add it to the virtual network at the time of creation? I can't see an option to change which Virtual Network the VM is connected to. Do you just have to do it at the time you create the VM, and if you don't do it then you will need to re-create the VM and delete the existing one? Example of the scenario: No VM's or Virtual Networks exist I create a VM (VM1), there is no virtual network so it isn't added to one Later I create a Virtual Network in Azure (Network1) It is possible to create another VM (VM2) and connect it to the Virtual Network (Network1), but can I connect VM1 to Network1 or must I delete VM1 and re-create it to get it connected to Network1?

• BSOD constantly with same ntoskrnl.exe error and disk indicator is frozen

  - by Sheep

  BSOD constantly and the disk indicator is frozen. Error do not happen immediately, usually an hour after boot up. Here is the Minidump: Bug Check Code = 0x00000124 Caused By Driver = ntoskrnl.exe Caused By Address = ntoskrnl.exe+4b094c Crash Address = ntoskrnl.exe+4b094c Seems to be hardware problem, but I checked RAM, no error. I have two HDs installed, system is on SSD, data is on HDD. Checked SSD with the properties-tools-error-checking , no error. Re-installed several times, still happens even after removed HDD. Configuration: SSD: Crucial M4-CT064M4SSD2 with Firmware 0009 Intel HM65 CPU: i7-2630QM The SSD is set correctly, SATA III 6Gb/s enabled, and everything worked perfectly for nearly a year.

• Adjusting color on one monitor in Nvidia Surround

  - by Chris Stauffer

  I'm currently running three 2560x1440 screens using Nvidia Surround. Two monitors are Yamakasi Catleaps (cheap Korean jobs) and the third is the Achievia Shimian (also Korean). The Catleaps have great color reproduction, however the Shimian is exceptionally blue tinted. With normal monitors the required correction would require minimal effort to accomplish. But these Korean monitors do not have hardware controls to do it. For those who are unfamiliar, Nvidia Surround basically takes all three monitors and makes one big "monitor" out of all of them (Xinerama for GNU/Linux folk), at a resolution of 7680x1440 in my situation. Therefore, adjusting the color profile in the Nvidia control panel changes the settings for ALL of the monitors simultaneously. Thus, I am looking for some software to adjust the Shimian (perhaps by just selecting the pixels that that monitor encompasses). Does anyone know of such a program?

• How to make phone calls using a pc, modem, headphone and no actual phone instrument

  - by user18151

  Hi, I have a phone landline connection and I DO NOT have a phone instrument. I connect the cable into my laptop, and want to make calls using my laptop. I have an HDA CX20561 modem. I seem to be able to dial number using dialer.exe, though nothing seems to happen. From Microsoft kb http://support.microsoft.com/kb/958143, it looks like dialer.exe alone is not enough for the call. Can somebody tell me how to make and receive phone call with whatever hardware I have, i.e. what software will I need. Thanks.

• Convert video files for Maemo (Nokia N900) using ffmpeg/mencoder

  - by Vikrant Chaudhary

  I'm a newbie in video encoding so I'm looking for some expert advice. I'm looking to transcode media files with ffmpeg or mencoder (or something other) on Ubuntu for my Nokia N900 running Maemo. I'd prefer mencoder, because of ffmpeg's crazy dependencies. Video output should be AVC/H.264 (probably hardware accelerated on device). Audio output in AAC (should have preferred Vorbis but not supported natively and requires .mkv which is also not completely supported). Output video should retain the original aspect ratio. Resolution of screen is 800x480 (16:10). (Explanation of why-this-value-is-chosen would be really appreciated). Thanks.

• String manipulation of type String substitution in mathematical expression

  - by Peterstone

  Imagine something like exp(49/200)+(x-49/200) I want to pass as argument of the function "roundn" whatever operation that is not a addtion or a subtraction So my expresion became roundn(exp(roundn(49/200,n)),n)+(x - roundn(49/200,n) Well the expression I want to manipulate is this: exp(49/200)+exp(49/200)*(x-49/200)+1/2*exp(49/200)*(x-49/200)^2+1/6*exp(49/200)*(x- 49/200)^3+1/24*exp(49/200)*(x-49/200)^4+1/120*exp(49/200)*(x-49/200)^5+1/720*exp(49/200)*(x-49/200)^6+1/5040*exp(49/200)*(x-49/200)^7+1/40320*exp(49/200)*(x-49/200)^8+1/362880*exp(49/200)*(x-49/200)^9+1/3628800*exp(49/200)*(x-49/200)^10+1/39916800*exp(49/200)*(x-49/200)^11 I´m looking for a method (That include whatever program) not based in lenguage programming, as much batch or somithing like that...

• System time wrong after running ntpdate because DST ignored

  - by Ian Dunn

  When I run ntpdate, my system clock displays the time as an hour behind what it should be. I know that ntpdate does everything in UTC, so I'm guessing there's a timezone setting wrong and it's ignoring Daylight Savings Time, but I can't figure it out. Here's what I've done so far: ln -sf /usr/share/zoneinfo/EST /etc/localtime to set the timezone Set UTC=true in /etc/sysconfig/clock so that DST will be automatically applied date -s hh:mm::ss to set system clock correctly hwclock -systohc --utc to set the hardware clock correctly At this point date and hwclock both display the correct time. But if I then run ntpdate 0.us.pool.ntp.org, the date output is an hour behind what it should be. I've looked at a dozen tutorials and can't figure out what I'm doing wrong. Does anyone have any ideas?

• How do I troubleshoot CanoScan LIDE20 on Ubuntu 9.10 in VirtualBox?

  - by kara-marfia

  This may be a VirtualBox question more than anything else. The host OS is Win7, which sees the scanner, but has no drivers for it. VirtualBox sees & recognizes the scanner as "Cannon Scan" and shows "state captured" when I hover over USB devices. Searching gives me many happy reports of this particular scanner being well supported, and that SANE should work with it immediately (also listedin the Supported Hardware List. I get "no devices available" from XSane... and I'm not sure where else I can check. I'd like to see if VirtualBox is telling the truth and find out if the USB port is actually being fed into the virtual OS. Can anyone point me in the right direction of where/how to do that in Ubuntu? Or other bright ideas. I'm starting with a little project to add some zing to my beginner linux studies - I'm sure I haven't checked some obvious things, because I don't know them yet. ;)

• SCCM deploy from VMware XP image

  - by HannesFostie

  We recently set up the latest version of SCCM and I managed to capture a .wim image from a virtual machine (build and capture task sequence). I want to use this .wim file to deploy winXP to different hardware, and therefor need to add device drivers to the task sequence. I created a driver package per laptop type, and deployed for the first time. However, I am getting a BSOD (0x00007B) which leads me to believe theres a problem with the storage drivers. After adjusting the task sequence to try and point to the mass storage drivers (which are applied at F6, I suppose) I do not get a list of compatible drivers (the list is empty). I looked around, and found some issues regarding hdc class drivers that are not recognized as mass storage drivers. The workaround suggested changing the INF file to make the driver a SCSIAdapter class driver, and importing these again, but to no avail. The list remains empty. Any help is much appreciated

• Is there no such thing as a Gigabit switch?

  - by Torben Gundtofte-Bruun

  According to the manufacturer specification, even my rather plain desktop computer has "Gigabit Ethernet". So when I want to copy large files over the LAN (not Internet) it would make sense to have a gigabit switch. I'm searching eBay for a gigabit switch for a planned home network upgrade. The products I find are all labeled "gigabit" but they all have 24 x 10/100Mbit autosensing ports and sometimes 2 x 10/100/1000Mbit autosensing ports. It was my understanding that 10/100 is ancient and that modern computers have network interfaces that work with 1000Mbit, so it would make sense to get a switch that has 24 x 1000Mbit ports. Did I misunderstand, or are sellers (deliberately?) mislabeling older hardware? (Let's not dive into wired vs. wireless networks and how "N" wireless is fast. You'd be right, but not answering the question.)

• Dell Dimension running Fedora12 does a "Sleeping Beauty" and I am not a "handsome prince"!

  - by Jim Dobbs

  Dell Dimension 2350 with a Pentium IV processor and integrated video and network chips running Fedora12 does a "Sleeping Beauty" and I, apparently, am not am not a "handsome prince"! The system puts video and network to sleep and it will not wakeup. I have heard of this problem on laptops, but this is a tower. Any ideas or help is appreciated. I tried to ping the network card from another system and ping fails. The logs indicate that the system continues to be active. Pressing keyboard short-cut keys makes the disk light blink but neither the video or network card comes alive. Failing all else, are there any Linux commands that I could schedule in cron to pulse video and network adapters hourly that will keep them awake? Or, should I wait on Fedora13? Before this machine, I built a Dimension 2400 with Pentium IV and it had the same problem. Fedora9 on the same hardware is fine.

• Cannot assign port 4 to WAN on TP-Link WR740N by DD-WRT wiki

  - by Victor Sergienko

  I'm following the DD-WRT instruction to get TP-Link WR740N v3's Port 4 on a different VLAN, but this doesn't happen. First, I have no "Setup VLANs" settinngs tab in DD-WRT v24-sp2 (07/20/12) std r19519. I can get Internet on Wi-Fi if assigning eth1 to "WAN Port", but then all Ethernet ports get on the same VLAN and any wired connection grabs the DHCP address and Internet connection from router. When following the "old" instruction, if I run, say, nvram set vlan2ports="2 5*", should there appear a new interface, vlan2, in ifconfig, after ifconfig vlan2 up? It doesn't - does it mean there is no support for different VLANs in my software/hardware? What am I missing? Is it impossible to create more VLANs on TP-Link740?

• How do I set up my own proxy server?

  - by NJTechGuy

  This website (abc.com) slowed access from our original IP address. How do I implement my own proxy server to hide my IP while browsing abc.com? Do I need special hardware/software combo to achieve this? If I can generate about 5 proxies and alternate amongst those 5 while browsing abc.com would be awesome. Please suggest. Thanks guys! p.s : I want to know if I can generate proxy IPs of the type 123.34.21.140 prot 80 on my own? I want to use those IP/port combos in my Python scripts (urllib2/set_proxy).

• Win7 safe mode pretends it's Xp?

  - by Joachim Kerschbaumer

  hi there, just a question in between. a friend of mine brougth me a laptop that does not work anymore and wanted me to check whether i can do something. she told me its windows 7, and startup screen and login screen look like it. howevere, as she gets a bluescreen on startup it is only possible to boot in safe mode where the system pretends to be windows xp sp3. the system also may have 1 gig of ram but the system itself states that it has 954 mb of ram which is a value i´ve never seen before. is there everything corrupt from operating system to hardware, or am i just a newbie that does not know that windows 7 pretends to be winxp sp3 in safe mode? or is this laptop just the victim of an illegal, crazy copy of xp sold as win7? maybe some strange chinese stuff? i also recognized that the startup screen of Outlook Express is pronounced as "Outllok Express" (no typo) i´m kinda confused, maybe someone could put light into this ;) thanks

• Distributed, Parallel, Fault-tolerant File System

  - by Eddified

  There are so many choices that it's hard to know where to start. My requirements are these: Runs on Linux Most of the files will be between 5-9 MB in size. There will also be a significant number of small-ish jpgs (100px x 100px). All of the files need to be available over http. Redundancy -- ideally it would provide the space efficiency similar to RAID 5 of 75% (in RAID 5 this would be calculated thus: with 4 identical disks, 25% of the space is used for parity = 75% efficent) Must support several petabytes of data scalable runs on commodity hardware In addition, I look for these qualities, though they are not "requirements": Stable, mature file system Lots of momentum and support etc I would like some input as to which file system works best for the given requirements. Some people at my organization are leaning towards MogileFS, but I'm not convinced of the stability and momentum of that project. GlusterFS and Lustre, based on my limited research, appear to be better supported... Thoughts?

• Installing 2 DDR3 Sticks in MB with 4 Slots

  - by The Sasquatch

  Hey everyone, I just put together my first system that uses DDR3 memory. The motherboard I got is an ASUS M4A77T/USB3 and it has 4 DDR3 RAM slots. Looking in the manual for the MB it doesn't say anything about how to install the RAM as far as matching the pairs goes. I have 2 4GB sticks of RAM, and whether I put the sticks next to each other (of the 4 RAM slots, there are two blue ones next to each other and 2 black ones next to each other) or space them apart, The BIOS still shows that I have 8GB installed. I have been getting an IRQL_NOT_LESS_OR_EQUAL BSOD error, and have read in some other places that it could be hardware/RAM related. Does the RAM need to go in the A1, A2 slots (different colored but both A), or the A1 B1 slots? (A1 B1 are both the lovely blue color.) Any help would be awesome. THANKS!

• Connect server to router with workstation in between?

  - by letseatfood

  I have a server (9 yr old Dell with Ubuntu 10.04 Server Edition) and a workstation (Laptop with Vista) which are both connected to a router. The workstation is able to access the server via web browser for testing my web development projects. Since the server is old and does not have a wireless card, I am wondering if it is possible to connect the server directly to the workstation while maintaining the ability to connect to the server from the workstation. The reason is that the computers are in a separate room from the router and I am trying to limit the amount of wires on the floor, along with trying to avoid buying more hardware (like a wireless card). Thanks and I will be more than happy to clarify!
