OK, basically whenever I play a game (lately Dawn of War: Winter Assault if curious) in at most 20 minutes, my computer will either a.) exit game and return to windows citing some error with game or b.) restart citing error by 'unknown device driver' which is likely my video card. As you can imagine, both are *highly* annoying. Same problem occured on previous system, which had: Windows XP Pro ATI Radeon 9800 Pro 128 Soyo Dragon II plus MB Pentium IV 2.6GHz w/HT 1024MB PC3200 DDR RAM Audigy II Platinum and the new system: Windows XP Pro BFG 6800 GT Asus P4C800-E Deluxe MB Pentium IV 2.6GHz w/HT <-same as previous 1024MB PC3200 DDR RAM <-same as previous Audigy II Platinum <-same as previous ATI said it was obviously my fault, and BFG says it might be the card, but since it occured on two systems I can't see why. Could it be the memory/pentium/soundcard/harddrive? Why would it randomly crash all the time? I can provide any more information as required to assist the diagnosis. I'm a senior in Aerospace Engineering and damn do I need to relax after a long day of crappy homework, so any help is greatly appreciated.
