  1. Something very odd is going on with the PSU. first the computer would only come on for a second or two then shut off. so i got a new mobo from a friend but my windows cd isn't working, so i reinstalled the old mobo, but accidently left the 4-pin p4-12v header plugged in on the new mobo, the only thing, and now the old one fires right up. if i unplug that header from the other mobo it won't work, but aslong as its plugged in it does. by the way the old mobo doesn't have that p4-12v header. is there a way to make the PSU work with out having to have it plugged into the other mobo? thanks!

    If you have an Intel P4 or AMD64 CPU, those cables MUST be plugged in.
    Fill in your PC specs under 'User Profile', top left any page, so we can have a look.
