Ntoskrnl.exe 4a5f3c Windows 7 error

Hi everyone,

I've recently come across a rather unpleasant error. It only happens whenever i play call of duty 4. Suddenly the game freezes, i can't alt+tab or do anything else. When i restart the pc i get a notice that displays an error code. Further research on google led me to the fact that it was a ntoskrnl.exe error.
My system is about 2.5 years old and hasnt had any of these errors uptill the past 3 days

Here is a copy of the minidump file:

What i've done so far:
Downclocked my CPU back to stock (Has been stable for 2 years now)
Ran memory diagnostic test (windows). No errors
Up till this point i don't know what else to do, can any of you help me out?


Thanks,
Rod

first a question, how did you get COD4 to run on Win7, it's very hard to do, as for things to check, memory memtest86, and while you at it open an command prompt (All Programs, Accessories, right click on Command Prompt and select Run as Administrator" ), in the cmd prompt type sfc /scannow see what happens, download MalWareBytes(it's free) and run mbam.exe and see if you bit by something, and let us know how it goes

I'm not a big gamer, but it seems like your problem might be right in front of you. Look at your RAM usage while gaming and make sure you have the latest drivers for your hardware and BIOS. Memtest is what we use in house to test all of our RAM and customer systems, very trusted, I would recommend it also.

rOdderzz I have the same problem, except I play Battlefield Bad Company 2. Have you figured out the cause yet?
