Graphics glitches in DirectX

[redslurpee]

ever since i purchased my computer every time i play a DirectX game such as warcraft 3, Battlefield 1942, Medal of Honor, Ect. i can play for about 2 min. then my screen gets covered in random colored squares about 1x1 millimeter big. this also freezes my computers and forces a manual restart. i have downloaded new drivers for my video card and motherboard. i also reFormated my hard drive all to no avial. my system config. is:

Athlon XP 1800
Acorp VIAKT266A Mobo
256 Mb Crucial DDR RAM
Gainward GeForce 4 Ti 4200 64 Mb
Maxtor 40.00 Gb Hd
Windows 98 SE

Only DirectX games? What about OpenGL games?

Medal of Honor is OpenGL. So I'd guess your video card is overheating. Unfortunately, I'm not really sure how to fix that.

i don't think it is overheating becuse it runs fine for hours in: half life, UT2003 and U. plus i have a blow hole with a thermaltake 120 MM fan right above it and it is not overclocked. also this problem has only started when i purchased Warcraft 3, it has since spread to all the other listed games, before i bought that i had had no problems. and no i have not upgraded my system since then.

try downloading the a fresh copy latest drivers & Dx8.1b then install them... something has got corrupted with your current files

no-one shouts louder than someone who is being ignored, or in the case of techies, to be heard over the noise of their PC's ;-)

But if not even a format could help him? That sounds like a pretty rare problem. How about dust and things inside the case?
