Every game i install and play locks up. First the game(s) start perfectly fine and then in about 10-15 minutes the game locks up with a frozen screen.
I have Windows XP Home Edition
AMD Athlon Xp 3000+ ~2.2GHZ
512 Ram
NVIDIA GeForce FX 5200 128mb video card

My video driver is fully updated also. Please help

I have a similar problem. do your games sometimes jus crash to windows or your comp restarts? I did the driver updates and directx and all software pretty much is reinstalled. You might want to check those things first

I too have the same problems with my comp. Ive got simular specs to your system. Ive updated drivers for everything. Ive run Dxdiag, but i dont know what im looking for. Except mine crashes or freezes within 2-3minutes of playing, and it wasnt like this a week ago!
