I originally thought that my computer was crashing because of the heat that games caused, but appearently it only crashes on games with high graphics settings. When I try CS:Source on high settings, it crashes. Or I try to play FEAR on high settings, it crashes. However, if I play a less intense game like WoW on high settings, it doesn't crash. But the heat being generated is the same. So, I kind of came to the conclusion that it was my graphics cards causing the lockup.. because of the following: What seems to happen is the driver stops working, because one time when it locked up i got the game to minimize for a second or two before it locked up. I saw something about the driver in a popup box, but I can't remember exactly what it said. But, everything was reverted back to the extreme minimal settings.. resolution and color-wise) this may be completely irrelevant, just thought it might be important. And second, a lot of the time when i try to restart my computer, the computer will do the normal shutdown thingy and instead of booting back up it will just stay on a black screen (the computer is on, but the monitor isn't getting any video.. (i can tell its not getting video because the light flashes green and orange on the monitor -- which is does when i turn it on with the computer off) until i turn the computer off completely, and then back on. Anyway, I know that was long, but I hope you read it. Thanks, hope someone can tell me what might be causing the graphics card to crash, IF it even is the graphics card crashing.

I'd go for the theory of corrupt/outdated drivers... try upgrading to the newest driver versions as well as the newest DirectX version (9.0c). Also make sure that the games you're playing are fully or at least compatible enough with your card because as some readme files say "It may cause unkwnown results". If none of these works try removing your video card, clean it from possible dust and place it back into its slot. Ventilation is also important. Regards and hope this helps

You need at least a good (not cheapo) 350W power supply also.' Internet search engines are your friends. Morpheus: There is a difference between knowing the path and walking the path. "The Matrix"

Well, I've got a 400 W supply that came with my case. I calculated it once, I've got more than enough. I've tried reinstalling the latest graphic drivers. But I never tried removing them first.. maybe I'll try that. I've got the latest direct x9.0C. And as far as ventilation goes, I wouldn't know if my graphics card was over heating because I can't figure out how to check the temperature (sapphire radeon 9800 pro is my card). But I have another fan coming.. maybe that will help. Doubtful, though.

I have somewhat the same problem with mine...I think it's my graphics card too or either my motherboard, I can't tell??? But when I play intense games too it freezes and then my Radeon 9800 Pro's vpu recover thing pops up saying that it crashed and it's recovering. I only got this problem when I installed my new motherboard [ and if i want to switch mothboards to my old one, i would have to down grade my cpu =( ] And I have a 500 W PSU I don't think its overheating becuase my cpu/mobo/vpu are all low..

Very interesting that we both have the same problem, and we both have a radeon 9800 pro (mine is actually a sapphire ati radeon 9800 pro, 128mb, though --).. I think I'd feel better knowing that it was my graphics card and not my computer, though. I don't think it's my motherboard.
