    If the power supply and motherboard have worked together before, I would suspect the power supply has gone bad. You need to replace it with a quality unit that has the same or higher output capacity.

    By P4 cable, you are referring to the one with 2 yellow and 2 black wires? If two power supplies won't turn on then possibly the motherboard has a problem. CPUs rarely go bad. Have you recently made any changes to the computer?

    this usually indicates the m/board is the problem

    check it for bad caps

    Try to run memtes86+ on all your RAM sticks, if it has errors then that probably is the issue why your system is not booting.

    It is going to be really difficult to run memtest86+ on a computer that won't power on.

    He just reports that there is no display, hopefully he'll remove the RAM sticks and test out which one works then do a memtest. Or take out the RAM clean it a bit, insert it properly then find out which one works.

    problems associated with the aux plug and the m/board don't point to ram

    No, that is not what he reports; here is the first post in the thread. If you read it, you will see that the system does nothing other than a fan moves slightly. When the aux pw connector is removed, the fans spin and nothing else.

    The aux connector is what supplies pw to the VRs for the cpu. This points at a mb failure and NOT a ram problem.
