Intermittant mobo beep

[rhys]

Archived from groups: alt.comp.hardware.pc-homebuilt (More info?)

Hello,

I have an home-assembledt ASUS CUV4X-D mobo running two P3 CPUs with 1
gig of RAM. Very solid rig, even for nearly four years old. Few
problems of a hardware nature.

I run W2K with the latest service packs and the latest Award BIOS
upgrades. I haven't upgraded this machine for a few months, but I run
extensive AV and other security measures. This machine is not
overclocked, nor have I opened it for some time.

For the last couple of days, I am hearing a single, short beep of the
type I associate with the bios/POST process. I am using Motherboard
Monitor and all sensors are under 40 C and no obvious problems are
occuring with the processing...no blue screens or other halts.

I can source information that tells me how to interpret start-up
"beeps", but a single, once-hourly type of beep is new to me.

My only idea is that the lithium CMOS button battery may be on the way
out, although I estimate the rig's been off maybe 20 days out of the
last nearly four years.

Any thoughts? I had planned to install a wireless router today, but
this may be more important.

Thanks,

R.

Do you hear any sudden hard drive action? You might
run chkdsk c: /f and see if any bad spots or hangs. I
think CMOS is good for a bit longer than 4 years, and
so is the mobo .. but ... open the case, and look at the
electrolytics up near the cpu. You are looking for one
with a swollen top that is stained brownish. If you
see one, time for new mobo. I think you have an ASUS
mobo of just the right age for the China Capacitor
failure. I RMA'd every single ASUS mobo from that
time that I had in my labs .. all capacitor failure.
Another symptom of that is intermittant rebooting for
no apparent reason. Hmm .. I'd almost make a money
bet on that one.

No, not that I can detect.

No evidence of that, but I can try it on all three HDs.

OK, I can do that easily enough as the case covers come off.

No reboots. Just a lone, short "beep" every 90 minutes or so. It's new
to me, that's for sure.

Thanks for your thoughts.

Check your PSU voltages.

The fans and temps are handled by Motherboard Monitor, which has
worked flawlessly in all the versions I've run, and which loads with
every boot.

The warning I've set for MBM is a two-tone, "British ambulance" sort
of frequency, whereas the "lone beep" is very similar, if not the same
as, the power-on beep I get the once-a-week or so I reboot the
machine.

Thanks for thinking about it, though.

no actually MBM5 MONITORS your fans does not control them. The fan headers
on the mainboard and the bios hardware management controls them. There are
settings in the bios for alarms ,or are you saying you have turned them all
off?

I realize this.

The fan headers

I certainly haven't changed them...ever. I suppose I can check the
alarm settings in the BIOS and I will post the results.

It is possible dust or a verging-on-fail fan on the CPU or in the PSU
might trigger a purely BIOS alarm, but I have temp, voltage and fan
speed parameters set in MBM and nothing's being triggered there.

Which may not mean anything, I know, if the BIOS is set for a "closer
tolerance".

Will post back with numbers. Thanks.

R.

They seem fine, or at least within the normal variances.
