8800 Black Screen Crashing

[eggnoodle]

Have a bit of a problem.

My card is the Leadtek 8800 Ultra Leviathian Watercooled and I think this could be the reason for my current problems with cod4.

The game runs completely fine, then totally randomly after either a few minutes or sometimes hours. The screen goes completely Black, and then the pc eventually either hangs or reboots itself. The issue does not appear to be happening in assassins creed or ETQW, just COD 4.

Have tried a couple of different driver varients and am currently running the game on the latest ones 175.16.

Anyone else experiencing similar issues? If so how did you resolve them

Would I be correct in thinking its possibly overheating? if so, what gfx card temp monitors are there that can record logs etc so i can see after rebooting please? Rest of the machine runs cool at around the 20-25 degree mark even under full load.

Can anyone recommend a gfx card stress test program which would help show what the issue is?

Or is it a possible driver conflict issue?

Anyone with any ideas or suggestions?

Spec is below - Vista 64 system

cheers,

ATI Tool and it's sounding like overheating to me.

I ran my usual overclock of 621Mhz core, 1600Mhz Shader clock and 1000Mhz Memory recently and within 15 minutes of online play I had the same issue. I used Lavalys's Everest to watch the temps as that shows GPU (heatspreader I think) and diode which is usually 10'C hotter than the GPU temperature. I fired up the "Show 3D view" in ATI TOOL and within a few minutes at my usual overclock I'd see the card hit 105'C on the diode and 95'C on the heatspreader. When the card hit 95'C (105'C diode) the FPS more than halved and this gave the GPU to reduce heat and when it dropped temp the GPU released the proper overclocked speeds again.

All I did then was remove the GTX and removed a tiny bit of dust from the fan and no more crashing. I don't know what you'll have to do with your water set up . Maybe clean the old thermal gunk off and re-apply.

i use rivatuner for overclocking/temp monitoring. try furmark for stressing your card....

I would memtest your memory... tho its possible its a GPU related problem (I had similiar with COD4 and the 169.21 drivers).

During the warmer weather recently I was getting a lot of games drop suddenly to desktop or go to a black screen and hang - running memtest (the windows one) showed lots of random errors - which to me indicated a controller problem rather than memory failure... after a bit of trial and error I found the extra heat was pushing the northbridge over the top.

Well I have run the fur stress test and also viewed riva tuner whilst playing both cod and the stress test and the GPU temp does not exceed 60 degrees on full load - surely that cannot be too high a temp for an 8800 ultra?
I assume the tuner is accuract to a fair degree. Will try the suggested memtest and report back for more advice.

Cheers for help so far.

Edit* Memtest has come back all clear, so I have no idea what is up with it.

Could it possibly be a different system component? I can't think of anything other than the card overheat or driver conflict that could cause this sort of issue with a system.
