• My 386sx refuses to start in cold days

  - by Armadillo

  My old computer refuses to start in cold days. So, in really hot days (about 40ºC / 104ºF ) or even hotter, this PC usually starts, but in cold days, it wont. When the temperature is not in the "sweet-spot" the power light turns on for an half a second and then the computer turns off. But when it's really cold, not even the power light turns on, nor even a blink. Sometimes I use an Hair dryer, pointed directly to the PSU and that works great. 5 to 10 minutes is enough, depending on the ambient temperature. I think something is going wrong in my AT power supply. I can't replace this PSU for another because it has a non-standard size and connectors to power the motherboard. Does anybody have a clue about what it's failing in my PSU, so I can change that component (resistor, capacitor, ??, etc) and rock on with my 80386? Thanks

• Allow Domain Users to install software on their computers

  - by Christa

  How would I go about allowing a 'domain user' to install software on their computer. I have active directory and group policy in place. Is there a setting in group policy that would allow this? I don't really want to make the domain users domain admins as well. There is a way to do this by adding the user to their local admins group under computer management. I need this for about 50 users so that gets to be a long process with that many users. Server: Windows Server 2008 R2 Client Machines: Windows 7

• Problems with connecting to wireless network on windows 7

  - by Naveen

  I have a Dell laptop with Windows 7 (Home premium) 64 bit edition installed on it. I use a Wi-Fi router to browse the net. My problem is, I lose the network connection every 10 minutes or so. The network icon on the system tray shows the refresh icon and the status as "identifying network". The network is fine and works fine with my phone. I saw on the net this may be caused if I have enabled IPv6, so I disabled it but still problem persists. When I look at the event log I see the following entries: "Your computer was not assigned an address from the network (by the DHCP Server) for the Network Card with network address 0xXXXXXXXX. The following error occurred: 0x79. Your computer will continue to try and obtain an address on its own from the network address (DHCP) server." I have also installed VirtualBox(32 bit edition) on the laptop. Does anybody any solution to this?

• Windows 7 fresh install blank screen

  - by Neil Barnwell

  I've just installed Win7 Ultimate to my PC. During the install it reboots a couple of times, but 2nd or 3rd reboot I see the "Starting Windows..." message, but followed by a black screen. No mouse cursor, taskbar, anything. The monitor power light is blue (indicating it has a signal) and it was displaying the setup wizard with no problems whatsoever. Has anyone else witnessed this phenomenon? Many thanks in advance. UPDATE I booted in safe mode, and got a screen saying "Setup is preparing your computer for first use". That's brilliant, although a message box has popped up over that saying: Windows cannot complete instlalation in Safe Mode. To continue installing Windows, restart the computer. So I don't really have the opportunity to do any cleverness with drivers or anything. I guess I could try getting a different version of Win7 (I'm installing from an MSDN DVD).

• Home router for higher network loads

  - by Zizzencs

  I'm trying to find a replacement for my ASUS WL500GP router. Some constraints: my ISP now provides 120 Mbit bandwidth - the router must be able to handle it I have 3 computers and a laptop at home - the router must have at least 4 LAN ports and the WAN port I need to be able to do the following in parallel: use bittorrent with ~1000 connections transfer files from one home computer to another at high speed access one home computer from my workplace I don't really need wireless I don't really want two boxes to serve all these purposes. So I was searching for a router with 1 Gbit ports, jumbo frame support and good reviews, but haven't really found a promising candidate so far. Any suggestions?

• 1080p HD TV + what is minimum spec pc required to stream HD movie files to it?

  - by rutherford

  I want to stream hi-def (non flash-based) movies from my future minimum spec pc to my network-ready HDTV. What I want to know is a) when streaming from a computer (local wifi network), is the computer's cpu/video/ram resources used to the same extent as it would be if playing back on the computers local screen? If not what are the differences? b) So with streaming hd content what is the minimum spec processor I should go for, if i) only one TV is acting as client ii) two TVs are simultaneous clients.

• Mount remote drive by port forwarding

  - by Anushka

  I have a windows 7 computer at home and a remote windows XP machine with an external USB drive attached to it. I would like to be able to copy files to and from home/the remote USB drive. The problem is that the only way of contacting the work computer is by first sshing into a different remote linux machine as there is a firewall that prevents direct internet connection. I can see two possible solutions but I don't know how to do them. Set up winscp using ssh port forwarding via the linux box so that I can copy to and from the two windows machines. I assume that I would need to run an ssh server on the XP machine as well to do this? Mounting the remote USB drive on the remote windows machine from the home XP machine via ssh port forwarding again via the linux box. Does anyone know how to do either solution?

• RDP windows key jamming

  - by VBwhatnow

  There is a known bug in RDP; if you lock the screen while connected to a computer the computer you are connected to will have its windows key jammed. There are a few work arounds that involve hammering the windows key and re-locking the screen but this isn't a bug I want to put up with anymore. Microsoft has said they wont fix this bug because it's XP specific and they are only working on security bugs now because XP is at end of life. Is there any way I can fix this or am I just going to have to find an alternative remote desktop software.

• How to rotate attached monitor to notebook of Sony's Z-series?

  - by user67175

  Is it possible that Sony is selling a top of the line, hugely expensive computer that does not have the basic ability to rotate an attached monitor? Is it possible that the Z-series simply can't do this? The Windows control panel is missing the normal option for "rotation", as is the Nvidia control panel for "orientation" , no additional rotation software works. Sony sales says they do not know the answer to this. Sony technical supports says that the problem lies with Nvidia, Nvidia technical supports says the problem lies with Sony. Any advice for a fix for this short of returning the computer would be greatly appreciated. Also wondering if this problem is common to computers running Windows 7?

• How to disable screens turn off Windows 8.1

  - by Warpzit

  So recently my computer started turning my screen monitors off after a while without activity, if I move the mouse or hit the keyboard they turn back on. I just want them to stay on.

Now before you jump to conclusions this is what I've tryed: Disabled screen saver Power saving settings to high with following set: Turn of the display: Never Put the computer to sleep: Never Turn off hard disk after: Settings: Never Sleep: Sleep after: Settings: Never Display: Turn off display after: Settings: Never Display: Enable adaptive brightness: Settings: Off Multimedia settings: When sharing media: Settings: Prevent idling to sleep. Any pointers that get me in the right direction will be greatly appreciated.

• Cannot Ping PS3 Using a Wired Connection

  - by Post

  PS3 is using the inbuilt wireless network adapter (I cannot change this) When I try to ping the PS3 from ANY computer which is on a wired ethernet connection, I get Request Timed Out errors. Whenever I ping from a computer with a wireless connection, it works just fine. To be clear: Pinging from Wireless PC to Wireless PS3 works Pinging from Wired PC to Wireless PS3 fails I have tried this on several PC's and Laptops all with the same results. As an attempted solution I have set up static IP's on all related devices. More information: Default Gateway = 192.168.2.1 PS3(wireless) = 192.168.2.100 PC(wired) = 192.168.2.99 Subnet Mask(for both devices, I have made sure) = 255.255.255.0 Thanks

• How do I remove Lenovo Veriface from the login screen?

  - by Xenorose

  I have a Lenovo laptop which came preloaded with Windows 7. Every time I start the computer and get to the Windows log-in screen (where you enter the user password) I get a message about Veriface software giving me the option to use it. I'd like to disable this. I went over the Program's settings and there is nothing that allows you to disable it from loading with Windows. Also, I thought that it might be a service to disable, but I don't see it in the list of services, nor is it in the list of start-up Processes (either in msconfig or in the registry). I'm considering uninstalling it completely, but since it's a part of the lenovo software pack that came with the computer and I do use some of these software, I'm not sure if uninstalling it might also remove wanted things (and uninstalling and reinstalling if needed seems like a mess). Anybody know if there's an easy way to achieve this?

• Using git with cgit for decentralized/centralized development

  - by polemon

  I plan to use git for hosting my projects on my server. I've read about cgit, git-daemon, and I more or less decided to use those tools. But general use is still kind of confusing for me. What do I need to set up on the server, to push my files onto it. And when the files on the server are newer as the files on my computer, how do I merge them? Also, I use, say, two computers where I develop. How do I merge from one computer to the other? Also, when two people are working on the same project, how do they merge their local repos from one another? As you probably can tell by now, I come from SVN, but I've worked with Mercurial and now I'd like to test git.

• windows 7 partition disappeared

  - by atoMerz

  I have a VPCF2 with windows 7 installed on it. I was working on my computer when on of my drives (D) disappeared. I can see it in Computer Management>Disk Management and it'd marked as Healthy(Primary Partition). When I right click on it the only options that are enabled are Delete Volume and Help. So I cannot assign a drive letter to it (not even in safe mode). I tried System Restore and it failed. I tried to boot the system using ubuntu tha was installed on my system but that fails too because it was installed on partition D. I'm hopeless. What can I do?

• Hard drive clicking noise on Acer AO722

  - by Blank

  I'm running Ubuntu 11.10 on an Acer Aspire One 722. Whenever I'm on battery power I get a clicking sound from my hard drive every 5 seconds or so (this does not happen when the laptop is plugged in). I'm dual booting with Windows 7 and I don't get the clicking sound in Windows. The clicking sound stops when I run the command:sudo hdparm -B 254 /dev/sda Also, according to:sudo smartctl -H /dev/sda my hard drive is healthy. Is this clicking sound something I can just ignore? Or is it a serious problem and will it eventually damage my computer? If so, how would I fix it? I have tried adding hdparm -B 254 /dev/sda to my /etc/rc.local file, but I still run into the clicking problem if my computer boots while plugged in and is then unplugged. Also, I'm finding this fix to be unreliable. Sometimes it works, sometimes it does not. Is this a good solution and is there a better way of doing this? Also, would running my laptop with a -B value of 254 have any negative effects? (I read somewhere about a lower level protecting the hard drive from bumps)

• How do I force the system to look for new sound devices?

  - by John Zeringue

  I have a small flat screen TV (Toshiba) that I often connect via HDMI to my laptop (an HP Pavilion dv4) and use as a computer monitor. When I do this, I prefer to use the TV's speakers, particularly when I'm watching video, because the sound quality is much better. However, when I connect the HDMI cable after turning on my computer (rather than having it plugged in before booting up), Sound Settings does not list the TV as an output device, and I am forced to reboot. I was curious if there is an easier solution to this, perhaps a CLI command to check for new sound outputs. Does anyone know of something like this or have another solution? To clarify, I believe this is a software problem. The HDMI always works, and I can switch my desktop over to the TV at any time. The issue is that, if the HDMI wasn't connected during start up, the TV will not appear as an output option in the Sound Settings GUI. So, unless I'm mistaken, my question is not HDMI specific, but rather a general usage question about manipulating sound settings from the command line.

• Extremely slow desktop and laggy. Need help with graphics driver

  - by user171624

  I am a fresh newbie Ubuntu user and I just installed my first Ubuntu 13.04 onto my HP Slate 2. I did a liveCD on my USB drive and installed everything perfectly fine...nice and smooth, not a trace of lag. Then I rebooted using Ubuntu itself on the computer, it was extremely slow and laggy. Icons or any buttons doesn't trigger right away, the performance of the entire thing looks like either 0.25 fps to 1 fps. My HP Slate 2 information: Processor: Intel Atom Z670 1.5Ghz Memory Ram: 2.0 GB Videocard: Intel GMA 600 (PowerVr SGX535) SolidStateDrive(SSD): 32GB I tried installing the intel linux graphics driver and it failed to install because it said I don't have any intel based graphics card. Well...I do as you see above. What can I do? I can't get on the internet on it, I'm using my primary computer (Windows 7) to do all the searchings and put the files onto the USB to move it over to my tablet. Simply...I don't get it...using liveCD on USB, it was all nice and smooth...then after the installation...BOOM! Slow, laggy, and etc. Can anyone help me? Thanks!

• Discrete Math and Computing Course

  - by ShrimpCrackers

  I was recently admitted into a Computing and Software Systems program (basically software engineering) and one of the first courses I'll be taking is called Mathematical Principles of Computing. The course description: "Integrating mathematical principles with detailed instruction in computer programming. Explores mathematical reasoning and discrete structures through object-oriented programming. Includes algorithm analysis, basic abstract data types, and data structures." I'm not a fan of math, but I've been doing well in all my math classes mostly A's and B's ever since I started two years ago, and I've been doing math every quarter - never took a quarter without math - so I've been doing it all in sequence without gaps. However, I'm worried about this class. I've read briefly on what discrete math is and from what my advisor told me, its connection with computer science is that it has alot to do with proving algorithms. One thing that my instructors briefly touched on and never went into detail was proving algorithms, and when I tried, I just wasn't very good at mathematical induction. It's one of the things that I ignored every time it showed up in a homework problem (usually in Calculus III which I'm finishing up right now). Questions: 1. What can I expect from this class? 2. How can I prepare myself for this class? 3. Other tips? Thank you.

• How do I automatically download files to a Kindle 2 whenever its USB connection is plugged into a Windows 7 machine?

  - by Bob Cross

  The inspiration of this question is the Gadget Lab article How To Make Your Kindle Into an Automatic Instapaper. In that article, they describe an implementation of an Automator workflow that: Detects the connection of a portable disk (which the workflow assumes is the Kindle 2). Downloads the Instapaper mobi file containing the text version of the articles marked for "Read Later" to the computer. Downloads the mobi file from the computer to the Kindle 2. All of this is straightforward in terms of functionality but it is not immediately obvious how to do step 1 on a Windows box. Is the Task Scheduler the first step? If so, which event should be the trigger for the rest of the task?

• pscp: how to copy a file from a windows machine to a non-home location on another windows machine?

  - by help

  I want to copy a file from C:\temp on MachineA to C:\final on MachineB. I tried to use the following command, but it gave me an error (permission denied): C:\PROGRA~1\putty\pscp.exe -i C:\PROGRA~1\cwRsync\home\rcadmin\.ssh\id_rsa_private.ppk [email protected]:C:\final\test.txt C:\temp\test.txt It turned out I can only access C:\users\direcpc in my source computer. So if I put the file in C:\users\direcpc\text.txt, then it would work: C:\PROGRA~1\putty\pscp.exe -i C:\PROGRA~1\cwRsync\home\rcadmin\.ssh\id_rsa_private.ppk [email protected]:/test.txt C:\temp\test.txt But I want to access any location on my source computer instead of just my user home directory, is there a way to do this?

• games and movies become too slow after some time

  - by ishaq

  On my gaming desktop, I was fixing my desktop's power supply when something seemed to burn (I got that stinging burning smell). However when I turned ON the computer (it was OFF before), everything seemed to be fine. However, I have noticed that now it becomes too slow if I play a game or movie on it. I am talking about the computer becoming painfully slow after about 5 minutes into the movie/game (it works fine otherwise e.g. browsing), it becomes so slow I can see individual frames from movies/games. What could be the problem? A fried video card? friend memory (RAM), something else? My system's configuration is: Intel Core i7 CPU 3.40GHz 8GB DDR3 RAM 2TB WDC HDD NVIDIA GeForece GT 220 (1GB) Thermal Take Commander MS1 Chassis ( http://www.thermaltakeusa.com/Product.aspx?S=1394&ID=2051 ) mainboard: Intel DH67CL AAG10212-208 Realtek High Definition Audio

• How to add network printer remotely without knowing the IP?

  - by Steve

  Assume your friend from over 100km away asked you to add a network printer to his computer since you're so tech savvy. How would you add network printer remotely in this case? You would need: 0. Remote connection to your friend's computer 1. Printer IP and brand/model names 2. Respective drivers downloaded either from manufacturer's website or Windows Update driver Question is, how would you find out the IP address of the printer without bothering your friend too much with technical steps? Since your friend isn't as tech savvy as you - they wouldn't know which buttons to press to get IP address.
