Monitor has no signal now?

I'm trying to repair a friends computer, and ruling out option of this problem. The problem is the PC turns on, but the monitor is no getting any signal. Things I've tried:

1) I've used a new monitor (actually 3 different monitors to plug into the on board VGA slot)

2) Tried switching cables (actually all 3 cable I have work on other PC's)

3) Installed 2 different types of video cards and tried all 3 monitors (still nothing)

4) reseated and switched out the RAM

5) placed the HDD in a working PC and it works just fine

Now I don't know what to do to get this thing on. Any ideas?

Update:

The PSU is only a 150w BTW

Update 2:

...and there is absolutely nothing that displays on the screen as far as the BIOS. It checks for signal, then goes to sleep!

    I would say that based on what you have said there is ony a couple of other things.

    1. If you boot it up and the bios does not show any inforrmation on the screen

    The motherboard or PSU is bad.

    your problems are probably of the following:

    1) your motherboard is fried so try to replace it.

    2)the pci card on the motherboard is broken so try issue 1

    3) lack of drivers

    4)no bios (to fix use issues 1)

    hope this helps!

    I sounds like the motherboard has stopped working.
