Lately my system has been very unstable while playing games. AMD Athlon XP 3200 PC Chips Mobo (W30, i think) BFG 7800 GS OC (AGP, and new as of a few weeks ago) SoundBlaster Live! 5.1 (circa 2000) various HDs, 1+TB total storage. Half Life 2 Ep1 errors out with some crazy runtime error just about every time i play it for more than 15ish minutes. C&C3 just restarts the computer all together! The reason i'm thinking it could be the soundcard is cuz just before it restarts on C&C3, there's a weird sound that like, repeats itself 2-3 times, just seconds before the restart. I have no idea if this is a founded idea... or if i'm wrong. Any ideas would be great... i'm really pissed cuz i just got that new vid card and i still cant play games.
