ahh!!! power supply problem??!?!?!?

[Master of Reality]

I got up this morning and looked at my coputer to find it off. I checked the power cable and outlet and such and they all seem fine.

My power supply has made whirring noises and strange other sounds before (not within a week or two) so im thinking it may be it. I turned the power supply on and off and then hit the power button and sometimes i hear a click. I thought perhaps it could be a breaker in the power supply or something or the power supply trying to turn on.

Does anyone know any way i could test to make sure it is in fact the power supply that is the problem?  I will probly go down to the local computer shop and see if they know and see how much a new power supply will cost.

...it doesnt matter much if i buy a power suply and its not the problem because i have 3 other comps that need a P/S

They have power supply testers. Or you can use a wire stuck in the proper place to see if it will turn on or not.

Connect pins 4 and 6 (Green and black) to get the PSU to turn on without being connected to the motherboard.

When I've needed to do that I just hooked up the PSU from another machine. You don't even need to take it out of the case.

the cord wasnt long enough.. i did have to take it out of the other comp.... and it is the power supply. Im pretty lucky there was *one* of 14 computers that have another ATX power supply.

I think poltergeists are much more likely than some far-flung "power-supply problem" theory. Next you're going to claim aliens came into your room and unplugged it?
