Computer Freezing

This problem has been an on-going issue which nobody can seem to fix. My computer is a fairly good PC (specs in my sig), that was built about one year ago by the people at Velocity Micro. Here’s the catch; the PC has been freezing mid-game while I’m on FEAR, COD2, ect... but not all games are freezing just a specific few. I do have the latest Directx and all new drivers.
While playing those specific games my GPU master card is running at an average 65c for about 10mins then the game freezes the frame its currently in and locks up completely.
ADITIONAL SPECS:
-Windows Professional
-Arctic CPU cooler
-(a non SLI certified PSU)

Please post questions, suggestions, and any thing that may help out…..

Thanks,

temp is ok since the temp of a graphics card is different than a cpu so dnt worry it might b the ram im very sure so try removing 1 and test it

 

Thanks I'll try removing one stick...


And do you know if the PSU has to be SLI certified to run 2x 6800's?

pss no i dnt have a "sli" certified psu i have some generic psu called "colors" and everything is ok just try the ram

 

Thanks alot, it works fine now

 

what was it? the ram soo what did u do? remove it clean it? or buy a new 1?

 

Well it was the RAM that was having problems as u said it might be. It turns out that I have two 512mb sticks out of 4 that are faulty so I'm sending them to Velocity Micro (thats where I got them) for a new pair.

Thanks again for the help...
