On for about 2 secs. ????

[jemc]

I am running a P4 processor and a MachSpeed P4MFP533T motherboard. XP Pro.

I had some lighting over the weekend and the power went off for a few mins. Now when I try and turn on my computer, the fans( power supply fan and the processor fan will start to run but only stay on about 2 secs. then goes off. The computer will not power up. Does this sound like the power supply has gone bad or ???.

Thanks for any ideas you might have.

Sounds like something took a lightning hit. Your power supply is starting up so that wouldn't be my first guess. You can check that by trying your system with another power supply.

I would suspect a problem with on the motherboard or a peripheral card. If you have another vid card, try it. If you have a PCI network card or any other plugin, try removing it to see if that allows the system to start.

Good luck.

If the rig will do the same thing repeatedly, in quick succession, I would guess the mb and the cpu fan are not communicating. Could be either the fan or cpu. If you need to wait for at least several seconds before the switch will do anything again, I would guess a component failure resulting in a short. Best to strip the rig to mb, cpu, vid card, and one stick of ram. If it boots, add one piece at a time and test again.

FYI - I've seen this problem before, and don't discount any other suggestions - but sometimes the culprit is a faulty power switch. In such cases you may need to remove the front panel of the case to get at the power switch assembly. g/l

What I would try, is unplug the power chord to the PSU, reset the CMOS and also unplug the keyboard(I know this sounds strange, but it worked with my dads computer after a power outage). Leave everything unplugged and try again after 15 minutes.
