In BF2 and 3DMark05, usually within a 5-15 minutes, my monitor will shut off [orange light = sleep] and sound will go crazy. All I can do is hold my power button to shutdown manually. Happens right in the middle of a game/bench, not any other time. Won't happen in DOOM3/Source games/CoD:UO -- it seems like only on the bleeding edge games/benches. Have a two week old 6800GToc. Ran Cab and DriverCleaner, as in readme [<3]. Temps in EVEREST/Speedfan/ASUS PCProbe, they're right on. Clean comp, plenty of RAM, healthy as an ox. ForceWare v77.76b--checked v80.40b, v77.72, and one or two more. Antec TruePower430 [looks good, no spikes]. And probably did a bunch of other shnikeys I thought fit from other forums. Any ideas? Anyone seen a problem like this somewhere? Looking like a bad graphics card chipset to me.
