Asrock mo/brd - Model G31M-VS2
Using a known good psu that is 20 pin on the 24 pin connector on the board.
Also tried a 24 pin psu I believe to be good.
Just added a new cpu to this board. It's a dual quad conroe kentsfield.
There was a dual core cpu in this board and the voltages in the bios were all correct.
After the changes, the bios is showing the 5 volts as being only 0.61 volts.

What is going on with this thing ?
thanks for any help.

more info on this thing. booted the system into windows, than put the multimeter on both the 12volt and 5volt lines via a free mulox connector:
12volt is a little high. 5volt is reading 6.3volts.
This is a new power supply.
Can anyone help make sense of this mess?
