Computer shuts down......

Can you not borrow a PSU from a buddy and swap it in overnight?....really hate to see someone spend money when it might not necessary.....Also did you try kpac's suggestion  and point a fan into the open case ......

Hi, I have been trying to find one... Seems the only one I can find is a 250W but it is out of a P4! Will it be ok to try it if I do not plug in all my fans? I was thinking just the board and my hard drive to test them but I did not want to cause a problem by under powering it as the one I have now is 420W....

Count the pins on the motherboard connector (20 or 24) and match the connector on the psu....some PSUs' allow you to remove four pins on the end of the connector, all fans must be plugged in, even just seconds without can damage components.

seconds without fans would simpliy thermal shutdown (just shutdown suddenly)
running without a heatsink would damage the processor or motherboard

Well, I have 4 case fans in which I was referring to... I just changed out the psu and run a disk clean up and a AVG scan without a shutdown  ! Looks like it was my old psu after all.... Is there anything else I need to try before placing a order for a new one or should I be in the clear now?

Looks like you've found the problem....doublecheck the documentation on the new PSU and make sure it's the one you need.
