Hardware Monitor has found a problem....

[Jeff Kirkpatrick]

MB: Asus A7V
CPU: AMD Duron 600

Recently my computer has started to have problems. It began as
occasionally shutting itself off suddenly, both while using it, and
not. The CPU fan would continue to run, but everything else goes dead,
monitor, keyboard, etc.
Now, at boot-up I began gettting the message during POST:
"Hardware monitor has found a problem. Press delete..."

In BIOS I've found the following information:

MB Temp: 37C/98.5F
CPU Temp: 51C/123.5F
JTPWR Temp: -26C/14.5F

CPU Fan Speed 6108RPM
Power Fan Speed: N/A
Chasis Fan Speed: N/A

VCORE Voltage: 1.22V
+3.3V Voltage: 2.87V
+5V Voltage: 4.08V
+12 Voltage: 9.84V
-12V Voltage: -10.13V
-5V Voltage: -4.14

The last three readings appear in red, so I am assuming that's the
problem.

Sorry for my ignorance, but I have no idea what these readings mean,
or what may be causing the problem. I've tried to research it on the
ASUS website, but couldn't find anything relevant.

I'm hoping someone can shed some light and point me in the direction
of salvation. Can anyone help?

Thanks in advance.

Jeff

You need a new (larger) power supply for that system.

There could also be another explanation for this - a device in the
computer is drawing to much power (but may be functioning) and is
dragging down your system. A fan that has stopped spinning and is
shorted out will take down the 12v, but not the 5v. A hard drive uses
both 12v and 5v (as do most CD-Rom drives).

I would suggest that you get a 450W+ power supply for that system to
start with - they are as cheap as $50 most places.

Hm, possible problems:

*) weak/dying power supply
==> replace the power supply unit

*) high resistance at mainboard connector.
this leads to a quite high heat dissipation
at the connector, thus melting and burning
the plastic of the connector.

==> if not burnt totally, clean the pins of the connectors
otherwise replace the power supply unit.

It is worth pointing out, that two of these rails (the -12v, and -5v), are
often not used at all, and will have only a tiny current drawn on them. This
makes a failing connector unlikely to be the problem. Though the other rails
are not 'in red', I'd be more worried about the 3.3v, and Vcore voltages,
which are generally more critical than the +/-12v rails for instance. In the
past the 5v rail would be critical, it is now not used by so much.
Realistically, I have to agree that all the symptoms are of a PSU having
problems. A massive overload on (say) the 12v rail, could have the effect of
lowering all the voltages, but given the current available from the supply,
there would probably be some signs of heat if this was happening.

Im impressed that the bios even runs with those volts.
And the CPU is still drawing enough to run hottish.

-If it runs that hot at 1.2 vCore, it must cook at full power?

*hmmmmmm* cooked socket

[as a side note, before I get another AMD fanboy mailing me, I'm quite
aware newer AMD thermal design is just as good (and in some respects
better) as Intels current designs, I make this post in jest, and because

Thanks, I do have a spare power supply so I'll give that a go.

Cheers!

Thanks for the info, I know I will end up upgrading eventually, so I
probably pick up a 450.

Hehe, I wouldnt expect my own to frazzle at 51c, but its a curious
situation - running bios with power ~apperently down by 30%, still/aready
hotter than whats good for starting with (anticipating warmer days to come)

 

[DaveW]

Your power supply unit is failing. It is putting out inadequate voltage.
Time to replace it.

I've replaced the power supply (Thanks again guys!!), and now the voltage
readings are normal. However, it is still running at 51C. I think this
would be fixed by applying some arctic silver, no?
I took off the fan awhile back to clean the dust off, and I didn't apply
anything. Now I know I should of.

Sorry, after thinking about it, I wanted to clarify. A 450w would be ok to
use? I was using a 250, and that's what I had as a spare, so I threw that
in. But would it be ok to use a 450W with an A7V board? Or does it matter?

When you apply heat-sink paste you only apply the absolute minimum to
make the two uneven surfaces have better contact. Meaning that to much
paste acts as an insulator - it should be about as much as you can leave
on after scraping it off both surfaces with a sharp razor blade.

As for your other question - there is NO problem using a larger wattage
PS, in fact, a 450W PSU should also produce less heat and have better
ripple rejection and smoother DC output.

Wicked... thanks! I'll definitely pick one up.

-neednt cool it too much.
Heat is strongly proportional to cheapness of
cpu and whirrr of fan. My fans are very quiet now
at around 45C bios temp for running at 1.6 Ghz.

Is artic silver conductive electricaly?

I got £1.50p syringes of heat conductive & electricaly insulating
non toxic paste, no-brand from maplins. Great stuff, doesnt matter if it
smudges. The syringe with a few cc's contains enough to install hundreds of
heatsinks wastefuly ]

It appears to be that your power supply is dying. Most power supplies
derive the regulation for all of the other voltages from the
regulation of one of the voltage rails (generally the +5 volt supply
rail is the master). If everything is low, this would be a place to
start. However.... The only way to really know is to measure the
voltage with a good voltmeter. I don't trust the accuracy of the on
board monitor. It might be OK, but I just don't trust it. It is easy
to measure the +5 supply at one of the extra hard drive power
connectors. The 2 black wires are ground, the red is +5 and the yellow
is +12. Just stick the probes of a voltmeter into the black and red,
then black and yellow. Compare these readings to the monitor.
