Just checking my brother pc, put on some monitoring software to check the
voltages etc on the motherboard etc. I notice the +12V is reading 16.32V and
the -12V is at 4.01V. Is it new power supply time?

Bios power monitoring shows similar readings...

Machine seems stable though...

Most Monitoring software can be unreliable if it does not match the PC Board
correctly, go get a cheap DVM..

But matches with what the bios is showing..must be a fault

System couldn't be running at those voltages - must be a sensor fault. (You
could check the voltages with a multimeter)

Software & bios use the same sensors. Most likely to be a fault in the
sensor rather than the PSU.

System probably doesn't use -12V, the only things using +12V without
further regulation are drive motors but yes - sensor fault most likely.

What EMB said. You really need to go to DSE and spend $20 on a cheap DVM. I
finally found the cash and it's good knowing exactly what the voltages are.
As it turned out, my software/monitoring chip was reading correctly but at
least I was able to confirm it.

Bought this little cheap thing, a UNI-T UT20B, cost $20 and does an adequate
job for testing PSU voltages.

Available at the momment for $9.80

Double check with a good multimeter. Take readings under load, not from
an unloaded supply.

The first thing to eliminate is a faulty voltage sensor.
