My friend took his PC to bestbuy and they told him it was the motherboard. The PC will not boot at all, green light is on power supply. He told me they tested the PSU and it was good. So he bought a motherboard and I replaced it for him. I still cannot get the PC to budge. Could it possibly be the power switch (Its all I can think of at the moment) ... How can I test the power switch to see if its faulty?
