Hardware Monitor Detected WHAT?

[Marty]

Sometimes (seems to be mainly after system is powered on after having cooled
off) I get the boot message that Hardware monitor detected an error and I
should go into the power menu to check it out.

When I go in there, I don't see anything that jumps out at me as really
wrong. The temps are about 100º F for MB and 120º for CPU. Both fans
spinning a couple thousand RPM. Voltages are close to what the legend
indicates. I do notice the CPU core voltage is a little higher (1.55v) than
the max. voltage indicated on the box the CPU came in (1.525v).

How can I tell what the "hardware monitor" is complaining about? I have
found no documentation on what ranges of values the monitor considers
acceptable. I would hate to disable all the monitoring to get rid of the
error.

I wonder if the power supply just takes a couple of seconds too long to
stabilize, or maybe the cheap case fan spinning up to speed generates the
error?

I wish the BIOS was a little more explicit about indicating which
measurement it considers a problem.

If I could get the error consistently, I could disable the monitors one at a
time to determine which on is the problem, but I can't.

Thanks,

Hardware monitors need to have their alarm pre-sets adjusted to the
limits of tolerances for the devices they are checking. For example, the
tolerance for voltage is usually plus/minus 10%. For a 1.5 V supply, the
upper setting could be 1.65 V. The Tmax for an Intel CPU is typically
around 70 deg. C (or 158 deg. F). If Asus Probe was installed, then it
should have pre-set the proper defaults.

Mine complains about the fan in my PS, which is connected to one of
the headers. By the time I get into the BIOS, the fan has already
managed to squeeze past the limit, so simply exiting is all it needs.
Many power supplies have thermally controlled fans, and it takes
30 seconds for them to develop a reasonable rotation rate.

Thanks for your suggestion.

I had not installed ASUS Probe, but I have now. Unless I am misunderstanding
something, ASUS Probe looks to be simply an application for monitoring the
various levels while the PC is in use. Even though you set thresholds in
ASUS Probe, it does not look like those in any way influence what the
BIOS-level hardware monitor will consider an error during boot-up.

However, it was useful to see what ASUS thinks are reasonable levels in the
probe defaults. Based on those numbers, all my stuff is well within the
acceptable range and I still don't know what the boot error is about.

Likely one of the monitored parameters was out of range when the system
powered on, but came back to normal before you entered the BIOS. Some
thermally-controlled fans may do this if the minimum RPM is below the limit
of the BIOS's acceptable range, in this case you might have to disable the
BIOS hardware monitoring.

Thanks. I finally caught it in the act and the case fan was highlighted red
when I got into the BIOS hardware monitor. It was running about 1700RPM. The
fan is a cheap sleeve bearing fan that came with the case, and it does make
a hell of a lot of noise untill it gets going, then it spins quietly at
about 2500RPM.

Mine appears to have been the case fan spinning up too slowly to please the
BIOS. I finally caught it still red in the BIOS hardware monitor at about
1700RPM.
