ok i need help with this one: whenever i try and play ANY game, after about 1 and a half minutes into playing, it freezes for about 3 minutes, then resumes for a second, then freezes, and continues to do so until i ctrl+alt+del or turn the damn thing off. ive tried reinstalling, and installing older video card drivers (have a geforce ti4600), tried reinstalling directx. and still the problem. even reinstalled XP. now im thinking it would be ram, or the video card? i dont know. can someone tell me??
