It passed orthos for 9hrs and all 3D tests/benchmarks that were available. CPU was running at 3.7GHz with memory at 1:1 on the 9x multi. I was quite happy with it until I loaded up UT2004 and began playing. 10 minutes in and CRASH...the system locked up. Had to up the vcore a little and all was well. Similarly, the system in my sig did the same thing. Running along fine at 3.72GHz, passed all previously mentioned benchmarks and I started to do some video editing and again, CRASH...had to up the vocre a little again. But the good news was, both times a small bump in vcore made everything alright.
Thanks for the reply but as i suspected vcore wasnt the issue, i tried an old 6800gs i had lying around and left machine idling all night and low and behold it was fine, i noticed i had not changed the power settings after a fresh install of vista, i changed the setting to high performance put my 8800gts back in and left to idle over night and all was ok in the morning. I presumme that because the 8800 gts needs more power that it didnt like the power setting ? and when i tried to wake the pc the card was casuing the problem.

Im sure nobody will make this mistake but just in case i thought i post my findings
