Hi my computer keeps crashing and I don't know why.

At first I thought because I had my cpu over clocked that it all of sudden was crashing. So I set my cpu back to regular speed. This did not help.

I then thought it was because 2 sticks of my memory where from a computer that suffered from a power surge. However I just ran the windows memory diagnostic tool( extended) and after like 6 hours of testing my memory it found no errors.

So now the only thing that is left is windows 7 64bit. I first over clocked my cpu for a couple months while running XP. Never had a problem. I installed the memory and windows 7 at the same time.

But I not sure if it is my memory now since it passed the diagnostic tests. However I am not sure if it is windows 7 either has I installed it twice in the last year. I really don't want to go back to XP to find out if this is the case.

So here are my blue screens of deaths(from bluescreen).
