Those readings probably aren't too accurate, but that 12V reading in BIOS looks pretty low. It's possible that the PSU's finally giving up the ghost since the BIOS readings should be close enough to give you an idea where it's at vs. using sensors in a running OS. Other than that the motherboard could be dying, but I'd try a newer PSU first to test at least.
I've had BIOS/HWMonitor read 10V instead of 12V on a perfectly good PSU. The only good way is to get a multimeter.
