    You meant PS2 Keyboard, didn't you? It can be a pain sometimes getting into the BIOS with a USB keyboard on some motherboards. That's why I keep and old generic PS2 keyboard in the closet.

    Sorry I changed it to keyboard.

    Also try a different power cord in the power supply. I've had one of those actually fail on me and it was the last thing I suspected. It had me scratching my head for a while.
    Agreed.
    I had boot problems caused by a broken power wire or dodgy power connector on one of my optical drives.
    The drive couldn't power up and that prevented Windows from booting (somehow).

    Cant the operator just do the paperclip test with a molex fan for makin sure the PSU powers up?

    To answer your question; all that test is the switching to prove the power supply turns on and can power a fan. It does not prove that it can power up everything else in the computer. You can buy a power supply tester which puts a simulated load on the power supply or most computer repair shops have one for testing power supplies.

    Exactly, Its a quick and dirty test to see if its completely shot. If it won't turn on thats a very good sign that you need a new power supply. Even if it does turn on, it could still have issues. I do believe the OP has already done that. There are two threads on the go dealing with this problem.
