My computer has been freezing/blue screening for the past 2-3 days and after searching the internet I have been unable to find a solution to my problem.

The first crash initially happened when I was playing Guild Wars 2 and the computer froze up. I thought nothing of it and shut the computer down, walked away, and then came back after a short break. It froze upon booting at the welcome screen. I kept trying over and over but it kept freezing at the welcome screen or when trying to input my password to unlock my computer. I ended up giving up and going to sleep as it was already 1-2am.

The next day I turned the computer on and everything seemed to work fine. I ran P95 for an hour and 30 min and no errors reported. I ran a full system scan and no viruses were reported. I figured this is odd and proceeded to play Guild Wars 2. (I started playing after the computer has been running for at least 5 hours now).
After about an hour of playing the game froze and whole computer locked up again. After this freeze it kept blue screening and freezing over and over. I ran MemTest86+ and tested my memory and did 2 passes with 0 errors. I also ran CHKDSK from within windows and no errors were reported. At this point I just turned the computer off and went to sleep again.

The next day the same thing happened and the computer worked fine. An hour into guild wars and it froze. I turned it back on and it lasted a little bit longer then froze again. After all this I decided to backup and format my computer and install a fresh copy of windows 7. During the installation of windows 7 it went fine. Once I tried to update my windows it crashed a few times and things like that.

I am really unsure of what this problem might be now. I'm currently updating the computer without any issues. I'm thinking it's a hardware issue but unsure of how to go about checking which part is causing the problem. Also temps on the graphic card and CPU are fine. GPU about 60-65C in game. CPU like 60C max with P95 running.

Any help would be greatly appreciated. Thanks!

1) Ran HD Tune Pro. No damaged blocks reported on hard drive.
2) Ran FurMark. No crashing occurred while using FurMark.
3) Re-seated RAM, Video card and checked all connections. Cleared CMOS by taking battery out and reinstalling windows. I got a logon process initialization failure after it finished installing and rebooted itself... Now installing mobo drivers and updates.
