I have an old PC with P2 300Mhz processor.  It's on a UPS (APC 250).  We had a power outage a week ago but my pc was not on although the UPS was.  I turned the UPS off due to the annoying beep due to power outage.  I recently turned my pc on but realized I had the UPS off so I turned that on.  What happens is that all the devices, (disk drive, CD drive seem busy - led lights are on) then the monitor goes into sleep mode because it doesn't detect any activity.  The devices stay busy and the pc does not boot up.  Worse yet, I cannot turn the pc off using the pc button.  I have to turn the UPS off.  I've tried various ways of unplugging to see if anything resest but to no avail.  Any idea what may be causing it or how to un-busy the devices?  Thanks.

It could be a blown CPU, or a blown motherboard. That the drives still get power is only because they get it directly from the PSU. We can therefore determine that that one is ok.

In cases like this I would usually advise to test another CPU, or test the CPU in another motherboard. But because it is such an old PC, I don't know if you have a chance for that. P2 motherboards don't grow on the trees these days.

What you could try is removing the CMOS battery (with the power lead taken out of the PC, else it won't help), leave it out for up to 10 minutes, then place it back, plug the power cord back in and see if this reset the BIOS, if you can power on completely.

If you cannot, I still assume either the CPU or motherboard has gone to hardware heaven. Then all you could do with that PC is harvest it for parts. Sorry.

Thank you J.J.  I will try your suggestion of removing the CMOS battery.
