I'm having a look at a Win XP Asus P5S800-VM computer for a friend

I unplugged the HDD and the DVDRW. I entered BIOS setup and after
about
30
seconds it locks up. On starting I get Wrong date/time errors and also
an
error saying that the CPU overclock failed. I have tried this a couple
of
times after clearing the CMOS backup each time, but I still get a lock
up
on
the BIOS setup screen, normally while trying to correct the BIOS
time/date.

Would this indicate a screwed Motherboard?


I forgot to add..

Had already checked the CMOs battery and connections. Voltage was 2.85v
but
changed for a new one anyway. 3.08v.

I had a look at the online manual about overclocking, but there was no
indication of any specific jumper settings for enabling overclocking.

I have also checked the Intrusion/case open jumper and that seems fine.

I have run a voltage test..

Purple - 5.02v
Green - 0.16v
Grey - 0.97v (Low)
Orange - 3.28v
Red - 5.21v
Yellow - (When off 0.15v) Power on 11.15. (seems low)

Under Advanced, JumperFree Configuration in BIOS is the AI Overclock
Tuner.
Make sure that is set to standard. According to the manual, there is no
need
to clear the RTC RAM due to overclocking- it should reset itself after
doing
a shutdown and reboot. Make sure your CPU fan is clean and running. You
can
check your board temps and voltages in BIOS under Power, Hardware
Monitor.

Have changed the PSU and voltage on the 12v rail seemed better, 11.97v.
The fan is working and is now reasonably clean.
I navigated to the 'monitor hardware' section in BIOS and watched for a
few
minutes. Fan speed was on auto. CPU temprature climbed to 61.5 oC and the
motherboard temp stayed around the 27/28 oC mark. Then it locked up again.

Motherboard or CPU?


Depending on the model of CPU, that may or may not be high. My AMD in my
desktop never gets that high, but my Intel in my notebook will sometimes get
that high on intense programs, but drop right back down.
I haven't seen any mention of you changing out the RAM. Have you tried any
different RAM in it to see if that changes anything? If you have two or more
sticks, you could try them one at a time and see if that solves it. May be a
bad stick in there.
Are you using a USB keyboard or PS2? I'd go with a PS2 until the problem is
solved- just one more bus to eliminate. Since you don't have a HDD in it at
the moment, unplug the mouse, too.
Ain't troubleshooting fun :-)?
