My computer won't turn off, it only restarts

[Guest]

I'm having a really big problem, my computer wasn't turning off, it logged
off from windows and everything, but when it looks that the computer has
shutted down, it restarts. I had to kept press the power buttom so the
computer go off. I did that for about a week, and after that my hard drive
crashed and I lost all my information. I bought a new hard drive. I installed
windows xp sp2 in spanish and the computer won't turn off again, I cleared my
hard drive again and installed windows xp sp2 in english and it won't turn
off. I formatted my new hard drive again an installed windows xp sp1 in
english and at last it turn off. After that I only installed my mainboard
drivers. Today I upgraded my windows to sp2 and again, my computer won't turn
off. It kept restarting, I don't want to spoiled my new hard drive, please
anybody help me!!! I´m going crazy, I don't know what to do!!!!

It's an APM or ACPI (advanced power management) issue. Update your
motherboard BIOS and reinstall windows.

I already upgraded my BIOS after the first windows installation, I have an
INTEL D865PERL motherboard, with the best configuration available. I checked
in my BIOS and neither my USB or LAN are set to wake up my computer. I after
a power failure it set to stay off. I don't know what to do, I'm not sure but
could it be that my power supply is no good, or worst, that my motherboard is
the one thats failing.... I'm so desperate... HELP ME PLEASE!!!

I doubt it's the board and would certainly swop out the power supply
as a first check. I had the same problem the other day installing XP on
an older machine but a BIOS upgrade sorted it out. Make sure you
indeed have the latest BIOS version.

There's a truck-load of information on the page 'bobby' mentioned in
his reply. Work through that so long and good luck.
