Computer crashing while playing BF2

I came across this forum while searching for a solution to stop my computer from crashing. If anyone can offer help, it would be greatly appreciated, as I have been trying to solve this for a while now. My computer crashes when I am playing battlefield 2 and appears to be random. Sometimes I can play for hours before it crashes and sometimes only a few minutes. I have tried a lot of different things, but it is still happening. I have upgraded the power supply, added fans, got more memory, downloaded programs, etc… I have been trying to use Windbg to identify the problem but can't get it to load the correct symbol name; it's just a bunch of letters and numbers. Attached are several of the dump files if anyone can help identify the driver or problem. Thanks!

Hi,

I Believe that your windows is infected with virus. This is similar to the following case. The failing module name is different but it crashes at the same instruction address. Refer the following case to find out the solution
