(Using Windows XP Home, 1GiG ram, Intel Pentium 4 CPU 3.20GHz (2 CPUs) with NVIDIA GeForce 6800 GTO video card).
I used to play Diablo 2, Heroes of Might and Magic 5, Call of Duty 4, World of Warcraft, etc. all of which used to work fine on this computer a year ago but I quit playing for a while. I recently installed some of these games again only to find out that my computer crashes to snow and blue screens after a couple minutes of play. Sometimes my screen does this while performing normal operations outside the game (by normal I mean writing a paper, surfing the internet, etc.) so that's why I'm figuring it's a hardware problem.
The stop screen errors I'm getting are related to nv4_disp.dll (my video card driver) when playing games (PAGE_FAULT_IN_NONPAGED_AREA). My video card driver has always worked fine with these games however. I've tried downloading the latest drivers for EVERYTHING (processor, video card, sound card) and still getting the same problems. I've tried rolling back drivers. I've tried using an UPS (Uninterruptable Power Supply) in case it was a voltage issue. I've tried doing a PC restore (Dell has this option of rolling your computer back to how it originally came - kind of like reformatting your whole computer). None of these have worked so I'm guessing my video card and fans are just getting worn out? Maybe a battery needs to be replaced?
How do I find out what the problem is without having to spend a lot of money buying a bunch of parts I don't need?
Please help because all I have now is a reformatted computer with none of my music, pictures, or word documents that still won't play games.
