If it's 'bsod'ing even once formatted .. doesn't that mean it's a hardware thing?
Correct me if I'm wrong
Aye, in vista BSOD is a hardware thing. You can see them from software faults causing hardware faults (i.e. your power management is sending the wrong amount of power to a component).
The rule of thumb is, if you see one, don't do whatever causes the computer to blue screen again until you have isolated the problem. Otherwise whatever hardware problem is popping up will just get worse.
