In trouble shooting a problem for a friend who said when he powered up the machine it would go to the cmos screen or setup screen and would not go anywhere else. I get it home and it wont power up at all. No fan on power supply. No nothing. It seems very odd for all the sudden a power supply going bad from his house to mine. There is no reset or switch on the power supply. I unplugged the power lead from the supply to the mother board and plugged it back in. Is there something I can check short of getting a new power supply.
