STABILITY ISSUE
---------------------------
Time to chuck this mobo/CPU and start over, or can this be made to
work?

I put together this setup a couple of years ago, based on an ASUS
P5V800-MX board. Last year I upgraded the memory to 1.5 gig Corsair
DDR400 and got a Corsair HX520W power supply. I also added a 500 gig
Seagate HD planning to replace the old 160 gig (wound up leaving the
old one in and switch booting from one to the other as needed). I
installed the lastest BIOS. Xp home has all the updates.

I have the larger drive setup to boot Linux (Ubuntu) or Xp, and I use
them both. The old drive boots Xp.

The PC's been running okay with a Celeron D 2.8, although I've never
been thrilled with the performance. I just got a used dual core
Pentium D 920 cheap on eBay and installed it. As expected, it works a
lot faster. I like it. However, it will do a spontaneous reboot if
stressed. Unacceptable. This is not an Xp problem because it will do
the same thing in Linux -- load up a few resource-hungry applications
and start doing things and it will fail. Both cores are working and
show activity under Linux and Xp. Good, big Zalman CPU heat sink/fan
-- heat doesn't seem to be a prob.

Since I've only had the new CPU for a day or so; I'm not ready to give
up yet but I can't afford to spend much more time with it. I also
can't justify spending much money on it either. I figure if I spent
$200 on a new mobo/CPU/Memory combination and sold off the Celeron,
the D 920, mobo, and memory for $75 or so, I might justify going out-
of-pocket $125. That's what I'm trying to decide right now.

Anyone here have an idea about how to stabilize the system? BIOS
tweaks, or other tweaks/patches? I need to decide quickly if this can
be made to work or not.

Thanks in Advance, Alan.

I've copied below selected output from PC Wizard, in case that gives
you any clues.

Your voltages seem to be way out of spec, especially your +5V reading. Maybe try a different power supply to see if it fixes the problem.
