Guys please read my main post again.
The copy of Windows is good, it is the one I bought and have reused on the same comp after several reformats (which is legal).
It could be a bad file but how do I know what file is bad?
It does it when I am not transferring files as well sometimes.
I'm going to set it to full memory dump so next time it crashes I can write down what the BSOD says....
