BIOS not responding after overclocking

[roomscapers]

Hey y'all, I'm currently running a P8Z77-v LX mobo with 3570k and GTX970 with 600w psu, I've owned my rig for over 4 years and each winter I decide to overclock my CPU. Last year I was able to hit a stable 4.4ghz, but yesterday I went for a simple 4.2ghz. 

 

Then I restarted my computer, played games for a few hours then decided to increase to clock a bit more. This time, upon hitting EZ mode (it usually went straight to Advanced mode), everything freezes. The time doesn't update, fans don't change speed, and the mouse and keyboard don't respond. I figured it was because of the overclock and cleared my CMOS but that didn't change anything either. Any help would be appreciated!

A CMOS reset should've fixed everything up. Try taking everything you don't need out. In other words, unplug all your drives, all USB devices except keyboard and mouse, and maybe even your gpu. Keep one stick of ram in. Then clear cmos after that and boot into bios

I removed everything listed and still no luck. I just get an error code saying "the current bios setting do not fully support the boot device" which only showed after clearing the cmos or removing all the drives. It also recommends I change the CSM parameters. On this screen I'm able to move the mouse and my keyboard responds but after clicking okay, and going into EZ mode, everything freezes again

Solved it by flashing/updating the bios using my motherboards utility within windows( Asus AI suite 2)! Thanks for the help
