Hello,my pc experienced a lightning surge even though it was plugged in a surge protector (which was fried too). Now it won't even power on. The led on the mobo is lit but the green light at the front of the case will not come on. When I jumped the green wire and one of the black wire in the psu connector (after removing it from the mobo) the psu fan worked. When I reconnected the psu to the mobo nothing happens. What is the likely problem?
