Computer keeps booting into BIOS, but everything is fine after exiting.

This has been a minor nuisance for a couple months now. I tried googling it but a lot of people seem to have problems when the computer automatically boots into the BIOS.

For me, nothing seems to be wrong, I save and complete (F10 and ENTER), and the rest of the boot is perfectly fine. My computer hasn't had a problem, and knock on wood it actually does.

Windows boots perfectly fine, recognizes my disk drive order with my SSD first, and HDD second. No error messages, nothing pops up in the BIOS that was alarming. Fan speeds are running and my CPU cruises around 30 degrees on boot.

I have no idea to fix this. It's not a big deal, but I'd rather cut my boot time from 2 minutes to less than one again. Please help.
