Try the plastic soda straw trick.

Search the kitchen for a medium soda straw.  Liberate a Berg jumper, preferably 
the sort with a pull-tab tail.  Insert into one end of the soda straw, staple in 
place, wrap a turn of Scotch tape around it.

Now - unlike that old set of Kelly forceps from S-100 days, you can clear the MB 
CMOS w/o contortions, removing cards, or short-circuiting add-on cards.

Why so?

Modern MB with soft power-off keep an amp or more of power running about all 
over the board and bus in the power-off state.  This for power-on by wake-on-LAN 
(card has to be 'alive', no?), wake-on-keypress, and a host of other stuff.

Removing a card, attaching a cable, powering up with a not-fully-seated (either) 
*now and then* creates a spike that smacks a bit - or several - sidegodlin 
inside the BIOS alleged-NV RAM.

Too often these are interpreted as 'settings' that the BIOS UI could not set by 
menu, nor do they make good sense to the near-as-dammit 'state machine' the BIOS 
is supposed to present for later configuration as a proper Von Neumann 
architecture Turing machine.  But it tries....

So...

Pull the mains cord and do a five or ten count before attaching/detaching. 
inserting/removing.

Use yer soda-straw *in the mains-disconnected state* to do a 'hard' CMOS clear 
and start fresh when wonkiness of the sort you are seeing appears.

Don't be surprised that the issue goes away. Unless you have zapped the glue 
chips.

Which also happens 'now and then'.  'Specially on cold, dry, days with static 
build-up. Chipsets installed in a MB have pretty good protection.  But a 
lightening bolt - even nano-sized, is a formidable motivator.

HTH,
