Hardware Monitor says: "+12V boundary exceeded?" - Help please!

After having constant lockups on my computer, trying different fans, swapping RAM, I did a clean re-format and reinstalled win98. This time, while installing my FIC AZ11 Via 4in1 Drivers, I also installed a Hardware Monitor called '1st AID'

The second it started up, it told me '12 V boundary exceeded - immediately shut down!' w/ Skulls & crossbones all over (literally!) 🙁

There were 3 voltage reading/limits, and all were exceeded!

+12V - i had 15.5V!
+5V - i had 6.4 V
+3.3V - i had 3.43 V

My setup:
FIC AZ11 KT133 mobo
Duron 800, not o/c
Maxtor 30 gig
12x DVD
6x CD-RW
ATI 8meg Xpert98
128 mb Crucial

As you can see, nothing special, I was hoping at least for a stable machine. I have no idea what these voltages mean, or how I fix them. I looked in the mobo manual, but no help there.

Any ideas guys?? Thanks!
 
Maybe you need to change the power suppply. I don't think that the +3.3 @ 3.43 is a problem. My Soyo board sets 3.3 @ 3.55 by default. But 12 @ 15.5 sounds pretty far off. Sorry I can't offer advice. Think of this as a bump. 🙂
 
Thanks for the thoughts. I bought the case, power supply, motherboard, and cpu as a bundle from a local reseller. If the problem is with one of these, I can get them to fix it, I think.

Any other opinions?
 
Yes, the 3.3v seems Ok, the other two are too high.

In the motherboard's bios setup, is there voltage readout anywhere?

I would go by these readings, vs. the software readings.

If you can get a voltmeter and measure the voltages coming out of the power supply, this would give a better idea if the power supply is the problem or there is a problem on the motherboard's monitoring circuit.

Hmm... nope, no voltage reading in the BIOS, no temperature readings either.

I think I have a multimeter here somewhere...
 
Hmm.. Well, it is a 250 watt power supply, sorry I forgot to mention that. I'm going to talk to the dealer this afternoon. Hopefully he'll be willing to fix the problem, maybe replace the power supply?
 
Yeah and get a good one. I am using the 250W that came with my Aopen KF45A case but if I were to buy one today I'd get a 400W or better Enermax quiet PS.
