so i have been having a problem after i updated my z170 gaming 3 mobo to bios version f20. when i turn the computer on, every week or two it will almost immediately shut off, but turn itself back on. when this happens my OC is reset. i thought it was my OC all along but i have just experienced this with stock settings! i have updated to the newest version of f21, and it still happened. i am positive it is not my cmos battery because this started happening closely after updating. how can i revert back to an old verison of the bios? thanks

specs: mobo: gigabyte z170 gaming 3 mobo
psu: evga 850 GQ
cpu: i5 6600k
