I recently bought this new rig :
Asrock 939 dual sata 2 w/ all drivers
athlon 64 x2 3800+ w/ artic cooling 64 freezer pro
radeon 9800 pro 128mb (yes i know its crap) w/ latest Omega drivers
samsung 160gb sata 2 w/ 8mb cache
onboard realtek sound
1 gb ddr 400mhz ram w/ 3gb pf
win xp home w/ SP2
currently i've been experiencing a lot of crashing and possibly sound or graphics instabilities during games like fear and dod:s. (i havent tried less intensive games) i simply get random crashes during the game where the screen freezes and i've literally no control with the comp or the screen gets random rainbow coloured flashing and CTDs. once i restarted the comp after a crash and win xp told me that i got a BSOD due to unkown device drivers even though there was no blue screen.
i can't seem to figure the source of the problem - it can't be omega drivers coz i had the same thing with ati catalyst? I'm going to run a memtest soon and perhaps check temps.
