Power surge caused my first bios to get corrupted so it switched to the 2nd bios. I didn't notice any problems other than it telling me the bios has been reset until I switched the battery. I stopped getting the reset message but now I constantly get stutters just browsing a site, things like shockwave keep crashing and all of my games are taking much longer to load.

Using GA-Z77X-UD3H.

I just updated my bios using @bios but nothings changed.

I'd like to reset the bios from inside the motherboard and flip the dual bios switch but what state does my computer have to be in when I do it? Powered off or just completely disconnected?
