I have an older computer with a Gigabyte GA-P35-DS3L motherboard that
I home-built a few years back. I recently built a new computer and
have been keeping the old one alive until I get the new one all
checked out and settled in.

Yesterday the old computer wouldn't boot. It makes a BEEP about one
second long during the boot process but won't go any farther. The
drive lights flash and the monitor goes through its first sign of
lighting up, after I turn the computer on, but this is as far as it
goes. The monitor goes black and the activity lights on the front of
the computer flash a few times, then everything stops.

I've tried using the original Windows XP Pro installation disk, and
also a second boot disk that I slipstreamed with SP3 on it. Neither
boot disk will initiate a start-up process. The CD drive light flashes
a few times then quits and nothing more happens after the BEEP.

Any ideas as to what I might try next?

That model mobo apparently has an Award BIOS. One LONG beep from an
Award BIOS often indicates a memory error. I would start by re-seating
the RAM. If there is more than on stick of RAM try using just one, then
the other (in the first RAM slot).
If no improvement, try reseating the PCI cards and other items connected
to the motherboard (power connectors, etc).

It could be other things, but that's where to start.

Thanks, Glee, I followed your suggestion but didn't get any favorable
results.

I powered down, pulled the power cord then removed the RAM stick out
of the DDRII 2 slot then booted and still got the beep.

I then powered down pulled the power cord and removed the RAM stick
from the DDRII 1 slot and replaced it with the one I had removed from
the other slot. Still beeped at me.

I powered down again, pulled the power cord, then put the second RAM
stick into the DDRII 2 slot. This had the two RAM sticks switched
around from their original positions. Still got the beep.

Something I noticed...the CPU cooling fan seems to be erratic. That is
it will start running as soon as I click the switch to boot up, but it
stops then jiggles intermittently when the beep sound occurs. After
the beep sound, this fan starts running normally without further
interruption. Could this mean that the CPU has failed?
