P4T-E and the "Harware Monitor Found An Error" Problem

[Bill Anderson]

I built my system around an Asus P4T-E mobo almost exactly two years
ago, and it has given me good service ever since. I did have a problem
with heat buildup in the case at first, but after rearranging cables
that problem went away and I haven't thought of it since.

But lately the system has begun behaving erratically -- unexpected
shutdowns, not recognizing a drive on bootup, extremely slow opening
folders on the same drive. At first I thought "heat" -- so I removed
the side panel of the computer, and still had an unexpected shutdown
later. Then I thought "drive going bad," as the drive wasn't recognized
on bootup, so I replaced the drive and still had an unexpected shutdown
later.

But this morning, after an unexpected shutdown, on reboot I got the
"Hardware monitor found an error" message, entered Setup, looked under
Power, and found the 3.3V Voltage appearing in red and out of range. It
should have said something like 3.3V, but instead it said 3.68V, and
while I was watching it jumped to 3.71V and the system froze. I've done
no overclocking at all.

Could this have been caused by heat buildup, or is something else about
to fail? Any ideas? I've removed the side panel again, and I've been
using the computer all afternoon with no problems.

Check the power supply

You either have a bad motherboard or a bad power supply.

Sounds like your power supply is failing.

Thanks, Barry, and thanks to the others who replied. I've ordered a new
power supply -- PC Power and Cooling Silencer 400 ATX. My system has
crashed twice this morning, both times due to the same high voltage
problem. I've sprung for Fedex overnight. Hope this does the trick.
