I am running an AMD computer (system model AWRDACPI and Bios version "Award
Software International, 6.00 PG") which reboots by itselt. Often it will
reboot again before completely loading Windows (XP Home SP2). It also
occurs in Safe Mode. I ran a diagnostic today and the most common error is
this one:

AMLI: ACPI BIOS is attempting to write to an illegal IO port address
(0xcfc), which lies in 0xcf8 - 0xcff protected address range. This could
lead to system instability.

The error report was 12 pages with approximately 300 errors since January.
Any suggestions before I reformat the disk and reload everything?

Thanks.

I'll take a crack at that one and suggest that it's a memory error. Download
the memtest86 diagnostic at http://www.memtest86.com/ let it run through a
complete set. Won't hurt to try and it might come up with something. Formatting
the disk in a case like this is the last thing I would do!

That is not a system model. It's only a type of bios
"brand", not even a motherboard-specific brand.

That is a generic description of the bios architecture,
not telling in itself.

When the system posts, write down the other info, including
the long bios ID string at the bottom of the screen. If it
flashes by too fast to write down, press the <PAUSE> button
on your keyboard.

Check the board's capacitors for venting- cracked tops,
bulging, leaky residue on top or bottom, especially the
larger caps around the CPU socket or slot, near the memory
and (AGP?) slot.

As another poster has mentioned, run Memtest86 on it for
several hours.

You might try clearing the CMOS- see the user manual for the
method, or unplug it from AC and then remove the battery for
10 minutes.

More details on the specific make & Model of motherboard,
and itemization of other system components such as CPU,
video card, number of drives, and the make/model of power
supply, might help.
 
I don't know if it is a coincidence or not, but I pulled the tower out of
the little tower space in my desk, took the side cover off, and it has been
working fine for 3 days. It does a scan disk at start up because it says
that there is a disk inconsistency. There is no door on the tower space in
the desk, so there is plenty of airflow to dissipate heat coming from the
tower. Could there be any relation?

If merely removing the cover regains stability, odds are you
need more chassis airflow.
