I've been having problems with my computer recently and I noticed that the BIOS lists the status of both the 3.3V and 12V rails as 'Fail'. I tried replacing the PSU with another one that I have on a different computer, but nothing changed so I decided to update my BIOS - still nothing. Does anyone have any insight? Could it be the motherboard?

I actually changed it yesterday, so it can't be that.

Stick a volt meter on the power connectors and see what you get, but only if know what your doing.
