I think my power supply is dead cause i had my pc booting up off a powerpoint when the powerpoint got overloaded and cut out. now wont start.i know that the problem is not the power lead cause i tried it with another pc. the power isn't getting to the motherboard cause it has a light that goes on when it is getting power. i think it is either the motherboard( ASUS A8V) or the power supply(OCZ Powerstream 520). can any body help?
