I just recently tried to take my old athalon 900mhz mb/processor out of storage and toss it into a case for a filler computer to use. Unfortunatly when I try to power up the power comes on briefly, I hear/see the cpu and case fan come on, then they shut off. Nothing shows up on the monitor, no beeps, just fans on then off. I pulled all the memory out thinking it might have been bad/wrong speed but still same results. Once it shuts off it does not want to come back on, I have to wait a couple mins or unplug the power then plug it back in. Even shutting off the power supply switch does not seem to do it. I was using this case just this morning so I know the power supply is good. Is it likely that my cpu is toast? Or can you suggest something else I could try. Dont really want to spend a lot on this so any suggestions to fix are greatly appreciated. Thanks.
