PC Freezing


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.

Anyone know what might be causing this?

  1. Test the hard disks with manufacturer diagnostics and also test the memory with memtest86+.
  2. Hi evongugg,

    I have already ran memtest, orthos, prime, disk chk, 3dmark and got no errors or lock ups
  3. Check for a virus.

    It could be the Power supply also. Check the voltages in the Bios for fluctuations and levels. +-10% is a problem.
  4. 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.
  5. well at the moment i have removed the scsi controller and disks and re-building it using IDE, going to tr to rule out the scsi as the problem.

    I originally has the gpu and cpu on one loop so taught it was a heat issue. But have them on seperate loops and the temps are really low even under full load.

    The psu is fine i have tried the system with another one and still get the issues
  6. well i have just ruled out the scsi controller and scsi disks, as with just 1 ide hard drive it froze after 5 mins of WIC
  7. 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.
