dual voltage readings for a single core cpu (as if it wouldn't be odd on adual core as well lol)
plus the +12v is rather low.
it's either the psu or the mobo, and judging by your psu I'd say you rig's a bit overdue for a power supply upgrade.

Sorry, I'm not too good at voltage readings and PSU. If it was anything else I would gladly help, but not too good at these parts of computers. Anything else you need help with, please keep posting!

Yer, i had that problem before with voltage rails being displayed as out using SiSandra. The only way to really find out is to get hold of a multimeter, and then jump start your PSU. Test the voltages there, then when its running your PC, and then under heavy load, and see what the fluctuations are.

All the information on how to do these things is already available on TPU, i askd djjbenn for some advice, and he forwarded me the link :)

If you need any other advice you can add me on msn or message me:
