I am having a recurring problem with my pc locking up ever since i installed my Nvidia 6800GT card. It only happens when I'm playing games. It doesn't matter if it's a high graphic retail game or an online shockwave flash game. A few minutes into the game the computer will freeze. My system info is:
AMD Athlon 2700
1 gig RAM
Windows XP
I have removed and reinstalled the driver 3 times but it still happens. If anyone has any suggestions it would be greatly appreciated.

Check your settings via:

start Run... dxdiag

Do you have DirectX 9.0c?

Also open the Display tab and test the 3D tests.

Thanks for your response. I did all of the test and no problems were found. Yes I do have directX 9.0

Check your Event Viewer via Administrative Tools.

Open the System as well as Application tabs and look for red X errors that coincide with your problem. Details here:

Thanks for that advice. I did find many yellow and many red marks. Some said Application hang, some said CA_LIC, some said Application error, many said nview_info.

Event ID is a basic starting point to specify errors:

nview_info is nVidia software/drivers. If you have already uninstalled and reinstalled all nVidia software/drivers then perhaps try to disable nview_info which is just a setup/monitoring aspect of the software.

Can you tell me where to disable nview_info?

You all might be interested to know that I read another thread about a possible conflict between graphics cards and anti virus programs. I'm not a geek so i'm not sure how that can happen, however....I disabled my virus program and I have been playing over 12 hours without freezing up. Maybe this will mean something to someone. I just feel that I found the culprit. I think it's time to change programs. I am currently using Inoculate. Does anyone have any comments about that?

Inoculate is an antivirus program? havent heard of it. i usually just use AVG Antivirus or Norton, though i've heard that Norton screws up your computer and isn't recommendable.

i think most people would recommend AVG. i've tried Kaspersky before. it's pretty good but costs a bundle.

mind if you give a little detail about the Antivirus and Graphics conflict issue? it'd be nice to know.

I'm told that Inoculate is an old anti virus program, one of the first. I still have had no problems since i disabled it so it's history.
