Z77 Pro3 hangs at bios for 20+ seconds

[pkpkay]

When I first start my computer "Bios Splash Screen" stays on for about 20 seconds. Then it loads windows.
When I press tab this is the text I see.

AFTER 20 seconds....the following text loads very fast and the windows splash screen comes up.




Z77 Pro3 UEFI P1.20

Press F2 or DEL to run Setup
Press F11 for Boot Menu

The text above takes less than 1 second to load.
Does anyone have ANY idea what would cause bios to hang like that?

Try to remove all USB devices that are connected.

Tried that, didn't work. I even disabled Legacy USB support, still the long load time.

Perform CLR CMOS.

Tested it out, didn't work as well.
:( Appreciate the ideas though.
