COD4 keeps randomly crashing?

[dannykilla]

Hi,

I am getting problems with my COD4, every now and again I get a crash where the game freezes and after about a second the screen goes black, while black I can still here the in-game sounds, then after a few seconds on the black screen the game reappears for 1 second again and then back to the black screen again this repeats it self over and over until eventually I get a BSOD, then the system restarts after the memory has been dumped.

Now I have un-installed the Graphic drivers, rebooted and then installed the latest drivers and rebooted again. Loaded the game up joined a server and eventually I get the same thing happening.
Now the crashes seem to be random as far as I can see, but tonight I as I got a black screen I did the Ctrl+Alt+Delete and opened the taskbar and I got a pop up window (bottom right) saying something similar to this "the nvlddmkm display driver crashed and recovered.
So can anyone help please?

Thanks for the replies, I have attached an img of GPU-Z, my system has been on for about 10 mins.

So is it overheating?
and if so how do I increase the fan percentage to 100% instead of 60% ?
and will this help?

Thanks
Danny

Also as I was writing this post the GPU temp (the one under the memory clock one raised to 70`c

IS it now overheating ?

Thanks
Danny

**also it did raise to 80`c while writing this reply

I am continuing to run the ATITool and the GPU-Z and the temp is now at 103.0`c

so is this the reason for the crashing ?

works fine when I turn the fan up. Hopefully this works for you too.

How do I turn the fan up if you dont mind?
