I have a computer that likes to blow power supplies and i have no clue why. they really dont get blown is the kinda weird part. they will work for awhile in the computer (2-3 weeks), then it will randomly shut off and not turn back on. when i replace the supply with another, the computer starts, but the weird thing is that the "blown" supply will work in any other computer, just not this one again. anyone have any idea of what might be going on?
