I have a newly built PC with the following specs:
E8400 Core2Duo 3 GHZ
Asus P5E3 motherboard
4 x 1 GB sticks of CSX 1333 MHz RAM
***Inno3D NVIDIA 9800GX2 video card
2 Seagate HDDs in Raid 0 (on-board Intel ICH9R controller)
I am running a clean install of Vista x64, although the problem occurred on both WinXP and Vista x86 as well.
The problem is that on a cold PC I can play some 1-2 hours of Crysis, COD4 etc and then it starts freezing - no response from controls and the last audio sample keeps making an annoying repeating noise. If I leave my PC on during the day and try playing on a warm PC in the evening, the problem tends to occur immediately after some 0-5 minutes of play. CPU is running at no more than 60 degrees celsius and the graphics card, which I suspect to be the problem, can get up to 95 degrees. Anyone know how to tell for sure?
Agreed, a heat problem. You could try shoving in some extra case fans (if you don't have enough - the 12mm ones are good) or maybe look at an aftermarket cooler for your 9800gx2 (not sure if there are any for that though).
A nice big case will also help with cooling. Oh and make sure you have a decent psu too as this will help with the stability of your system
Here is a very good app for monitoring your temps (not just gfx):
Ok, seems like the problem is with the fan on the 9800gx2. It seems to be set at 45% of max, hence the temp goes to over 90 degrees celsius. When set to 75%, the temp goes to some 75 deg, and when set to 100% the temp does not exceed 65.
Temperature at 50 degrees with 100% fan with no load (idle).
I used the EVGA Precision utility, which looks more simple than Rivatuner.
