I have a new pc running XP Pro SP2 with
Intel Core2Duo E6700
Abit IN9 32xMax Mobo
4 Gb Corsair Dominator 8500
XFX 8800 Ultra XXX Edition
Corsair 620W PSU
Creative Xi-Fi Xtreme Music
Adaptec 29320A-R Scsi Controller
2 x 76Gb 15K HP Scsi Drives
2 x 146Gb Seagate Cheetah 15K Scsi Disks
I have put the CPU and GPU on seperate Water cooled loops.
The temps are all low even under load.
I have removed the ram and tried them 1 by 1 and also different ram.
I have just completed Bioshock on full settings even playing 8+ hours constant and never had 1 crash but when i try to play Settlers 6, WIC, MOH Airbourne i can get 30m-2hours play before it freezes its just random it could happen the second i load say HL2 Episode 2. I just reboot and i get no errors etc.
I have all the latest drivers, i have also uninstalled Mcafee and it made no difference.
This is interesting as it reflects a situation on one of my machines. All other programs run with stellar results but one will invariably cause the machine to freeze. I too, have tried various and extreme diagnostics in order to discern the problem with no results.
after all that it seems it may be the graphics card. Even though it played bioshock fully with no errors and passes 3dmark etc.
I tried a different mobo, psu, cpu ram and hard disk in the pc and it still froze ingame. So i tried the ram, psu, cpu in another stable pc and it ran fine but when i put the gpu in it froze. I then tried the gpu from that stable pc in mine and all games ran fine.
The ge-force 8800ultra on its own cooler get so bloody hot after a few seconds you physically burn your skin if you hit the cooler.
