thanks for the speedy reply. I'm really desperate to sort out this problem. How do I check the power supply?
Main Topics
Browse All TopicsI have recently upgraded my computer to Windows XP Pro and ever since i have been having issues with graphics and computer issues during games. When I play Guild Wars there are times when the screen freezes or turns black with the pointer set to the middle which usually lasts 30 secs or more, sometimes i have no choice but to restart the cpu because it doesnt respond to the keyboard either when the screen is black or frozen. There is also an issue with the monitor shutting off (the green led light turns orange) after it enters the black screen but the cpu is still running. i have also recieved the blue screen once, where it said that there was a problem with the ati driver.
This doesn't only happen when i play Guild Wars but Battlefield 2 and Counter-strike Source as well or even when I open my Adobe Photoshop. In Battlefield 2 the monitor also goes into stand-by and the 3D models are stretched and disorientated into 2d... i have no clue what is causing this. I have a Sapphire Radeon 9600SE 128MB, I have tried updating the ATI display driver for XP Pro but it still has not changed. it seems that this all started when I upgraded to XP Pro and I am wondering if these issues have to do with my video card . Do I have to replace my video card? Will appreciate your help and advice. Thank you.

There are power supply testers out there like this one: http://www.pcper.com/artic
Or you can make sure there's a load on the power supply such as hard drive and test it with a mutltimeter. If the board powers up you can leave the psu plugged into the board and test from the backside of the atx plug. If the machien will not power on, just short the green and black wires while the hard drive is plugged in for load, this can be done with a paperclip. That turns the power supply on, now test the following wires for dcv in the ranges listed.
Red, purple, and grey: 4.75 to 5.25 VDC
Yellow: 11.4 to 12.6 VDC
Orange: 3.17 to 3.4 VDC
White: -5.5 to -4.5 VDC (negative)
Blue: -13.2 to -10.8 VDC (negative)
Hope this helps.

It sounds like the video card is going into limp mode and not outputting signal. If your monitor detects no signal for x period of time it will automatically switch off.
How savvy are you at pulling your computer apart? Before changing any software settings, try reseating your video card, making sure you blow out any dust or accumulated crap. It's also worth turning the machine on and running it with the case off to observe if the video card fan is spinning properly.
Failing that:
- Set a SYSTEM RESTORE point.
- Download the most recent drivers for the mainboard chipset and video card from their respective websites.
- Go to Device Manager and uninstall the video card. Reboot.
- Windows will boot back with some generic drivers. Ignore the resolution or colour levels.
- Install the chipset drivers. Reboot if prompted.
- Install the video drivers. Reboot if prompted.
- Test functionality.
I upgraded to windows XP Professional with service pack 2. When I started upgrading to Windows XP Pro, my monitor just shut down but the pc is still running and I had to use my mom's monitor to finish the set-up. I have an Acer lcd monitor. Eversince then, whenever I play games or open photoshop, my pc shuts down after a few minutes. I re-installed the ATI driver thinking that maybe it will solve the problem but it did not.
I haven't really had the chance to pull my pc apart, I'm not savvy enough to do that but I will try to find out how to install chipset and video drivers,as suggested and hope it will help. Thank you all for your support, really appreciate your help.
You can try installing speedfan, it will show you the voltages and temperatures you have on your computer (just to check everything is as it should).
But as stated, make sure you install the latest motherboard chipset drivers, and then re-install the graphic card drivers - when upgrading to XP pro it might have overwritten some motherboard drivers.
Hello Everyone,
My apologies for not able to get back to you on the results of my problem. First of all I want to say thank you for all the comments that you have shared with me, I really appreciated all the information that was passed to me, unfortunately I had been offline the past few weeks and I did not have time to post a response at all.
To solve the problem, I decided to do some changes on my pc. My mom gave me a new video card for christmas , an ATI Radeon X1650 AGP. I bought myself a new tower case with lots of cooling and a new power supply. And then my mom arranged to have a pc tech do all the work. He contacted ATI support and he upgraded the motherboard driver and now my pc is working great, no more shut downs and overheating!!! And so with this posting, I am now closing this
question and once again, my sincere apologies to all and thank you very much for all your help.
kind regards,
PJ

It certainly sounds like a video card issue to me. I had similar problem, ram went bad on the video card. One thing to check first though, check the power supply. The voltage could be dropping enough to not power the card correctly. This would be cheaper than replacing video card.
