Motherboard voltage / temperature CRAZY

    The computer i'm having trouble with has the follow parts inside: an Asus P3V133 MB, slot 1, with celeron 450mhz, 192 mb ram, (one 128, and a 64 obviously). Power supply is a 300w. In the AGP i've got Voodoo Banshee. PCI's are a Actiontec modem, and Sound Blaster 16 in the other. 2 CD drives (CDR and CD) 1 HD (maxtor 80gb 7200) and of course a floppy. Also there are two USB devices, a flatbed scanner and a printer. (hope that's enough info)

    Prior to the SB16 in the PCI, I had a SB16 in the ISA which sounded aweful, so I switched it with the PCI. Now when I turn the PC on, it sends me to the bios saying the voltages are running amuck. Never had this problem before. Here's the numbers i've been getting:

       MB temp (RED) goes from 0 degrees to 255. (i'm guessing the minimum and the maximum allowable ranges)
       Vcore (was 1.98 to 2.0) Now is 4.1
       +3.3 is now +4.1
       +5 is now +6.9
       +12 is now +15.5
       -12 is now -14.2
       -5 is now -6.1

     Now what's really odd to me is that SOMETIMES after turning the power on, I can go straight in the BIOS and all the above values and temp are perfectly nominal... however give it anywhere from 8 seconds to a minute, and they all turn red with the numbers above. I'm afriad to keep it on for fear of shorting burning something out.

     So my question is this: Does this sound like
a) a power supply problem (the power supply is only a year old - it's been replaced)    

b) a motherboard problem, either the sensors have gone insane, the mb is shorting out to the chassis, or maybe a bios update would help?

c) somehow removing an ISA and replacing it with a PCI screwed something up.

or d) none of the above.

  Thanks in advance for any help.

OK, if your voltages and temps were REALLY going this far wrong, your system would be "toast".  Is it still working?  If so, I suspect that the program you are using is somehow incompatible with your hardware or some other part of the monitoring system is bad.
Pull out the PCI sound board and put the ISA one back in (or leave sound cards out altogether).  Boot up - is the problem still there or has it disappeared?
