I would try going back into the BIOS and resetting all default setttings. Once you are in the BIOS, there should be written instructions to restore default settings.
Then save those changes in the BIOS...and the system should reboot.
If this doesn't take care of it, then I would replace the CMOS battery for the system. It's probably a CR2032 battery, available anywhere selling photo/electronic/watch batteries (Walmart, Kmart, etc.).
Wacky things happen when it begins to run down.

FWIW: I think you have that BIOS version number set wrong.
