my computer randomly stopped working one day. it refused to boot. when i press the power switch, all the fans turn on, then right back off. i took out the processor, and tried it on another motheboard, and it tested fine. i used the same power supply with that board, so i know it's not the power supply. i then unplugged everything from the motherboard, took it out, and set it on a table, with a power supply. i hooked up the ATX, and the case switch. i pressed power, same thing, the fans on the motherboard spinned for a second then off again. what is wrong with this board?? if some can conclude some sort of permanent damage from the symptons, i'd like to junk this board. i paid $120 for it last year, and it makes me sick to look at its corpse, wondering if it'll ever work, so can someone tell me if it's dead? thanks b

When you turn on the power supply it supplies power to the motherboard (of course). The motherboard then checks all the voltages to make sure that they are within tolerances. If all is well, it will send a `Power Good' signal back to the power supply. If the power supply does not get this signal it shuts down. So there seems to be 3 possibilities: 1. The power supply is putting out a bad voltage. 2. The motherboard is failing to send the power good signal. 3. The power supply is not detecting the power good signal.

well, i am guessing it's suggestion #2, as the power supply seems to allow other motherboards to function... assuming it is #2, what would be the cause of this, and are there any possible remedies?

what PSU do you have?

It's a Future something, 400watt PSU.

What you might try is clear the CMOS. Just jumper it to clear it for about 10 seconds.
