NF7-S & 3000/400 Barton Random crashes

Hi
I have some symptoms and am looking for opinions.

I am running a Abit NF7-7 wit the AMD 3000/400mhz Barton. Everything in the
system is 3 months old. Has run flawlessly until the other day.

First thing it did was did not want to boot when it was cold. I let it warm
up for 5 minutes and it ran fine. I let it run 24/7 for a week and thne I
start to get a few random reboots which occured regardless of what was
running.

Today it did the random reboot but would not start back up. It just crashed
( no screen) and then would not respond. When attempting to boot up it would
not beep/ chirp or give any signals. All drives would spin up and the CDROM
lights would lite like it was going throught the boot process.
After letting it sit for a while I tried again. It started up fine and ran
for a minute and the crashed as before only now it would try to reboot and
fail and then just continue the loop of boot failures on its own.

I reseated the cards and checked the memory etc and restarted it. It
started to boot and stopped with the message that "the CPU was unusable or
had changed- check the CMOS". I did and it was as before. I notice on the
next atempt that it was idetifing as an AMD 050Mhz when I swear befroe it
said 3000.

I turned of the power and reset theCMOS jumper. But this did not change
anything.

I let it sit without power for an hour and retried it. It seem to be running
fine until I tried a CPU benchmark program on it. It crashed immediately.

Temps are normal.

Any opinions?

Looks like the CPU to me but was wondering what others thought.

I agree with Coco. Sounds suspiciously like a flaky PSU, not the CPU.

Had similar problems with an NF7-S which were cured with a new BIOS
battery. Old one measured 3 v but wasn't doing the job.

Well now that you mention it yesterday when I was working on it I got the
most prolonged run times after I shut off the PSU at the switch for about an
hour (cool down ?). I have another AMD rated unit in the garage. I will try
it.

It only had the problem when cold once now they have switched to warm.

John

I just did a CPU bench mark (Sandra) and i came back as running at 1.5Mhz
instead of the 2.1 it is suppose to. TheCMOS is set up as correct.

Could this still be a power supply problem?

dont trust sandra! it's full of errors! i have tested sandra a couple of
times and allways throwed it out with a promise not to install it any more.
i wont try sandra any more.

look at bios start screen and make a check with better program to verify.
(aida will do!)

AMD 3000 and NF7-S will ue more power than your previous system.

Well at this point I seem to have corrcted the problem without knowing what
I did!

It is running on its second day at full power with out a hickup. The Gremlin
must of escaped when I opened the case.

It is my guess that it is the power supply and or the battery. ( PSU is 430
watt Antec 6 months old).

If it misbehaves again I will swap out the PSU and se what that does.
Thanks for the help.
