ok guys, i got a gigabyte motherboard, 512 ddr, amd xp 2600 with a geforce 5200fx 128mb. ok all of a suddenly around 2 months ago, everytime i use something that require more graphics such as games, or media clips, my screen would start black out and twitch and then just freeze.. odd, i thought it was the driver so i re-installed many different versions still dont seem to solve the problem. i even reformatted my computer about 3 times. now i recently tried lowering my display hardware acceleration to middle poing, now i can watch media clips, but when i try to play games such as CS, it only enables software mode.. wtf?!? so im sure its my graphic card now. what can be wrong?? is it overheating? any sug??
