3.3V and 12V rails failure

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?

  1. did you check the little button battery on your motherboard if she still give the voltage mark on her
  2. I actually changed it yesterday, so it can't be that.
  3. Stick a volt meter on the power connectors and see what you get, but only if know what your doing.
