Is this a motherboard problem or psu problem?



My system is at 90% load.

BTW, my usb ports doesn't work properly if I connect 2 or more usb devices.

Is this the cause of my malfunctioning usb ports?

Almost certainly a measurement problem.

Your hard disks probably would not even spin up and I would be surprised if the system even POST'ed with less than 10v on the 12v line.

I would agree that it is not likely 6.8V on the 12V line. Seems like a bad sensor. Of course that doesn't mean that the 12V line isn't bad.
