BSOD Problem: minidumps attached and I am ready to fix this!

Attached are my minidump files. I have run into this problem basically ever since I built this computer (p4m8400PRO-M mobo, P 920 CPU, GEforce 6600 GT video). I noticed the random reboots, then it would crash everytime I attempted to play BF2. So I reinstalled everything, checking to see if I could play the game. I specifically checked the video card, and it was working fine. I have also tried various drivers for the card, with no difference. However, after a few of the windows updates I started getting the rebooting again, typically without a BSOD. I posted a few days ago about this, but got no response (probably because I did not attach the minidumps as I have done here!).
I am desperate to fix this problem, especially now that it crashes even when I try to install office on this computer. Let me know what I need to do. Thanks.

Also, I ran memtest86 and got 0 errors, and ran verifier with all drivers and got no problems, although before the reinstall I would get the BSOD running verifier...

 

I just uninstalled sp2 and got a new error while trying to install Office, this one says memory corruption. I swear I have gotten every kind of BSOD possible...

 

When I figure out what to open those dumps up with I'll be able to read it.

 

I attached the dumps themselves, you open them with windbg. Do you want me to run them myself then post them? I got the impression you wanted the actual dump files...
