Today i was plugging in my keyboard and mouse after removing it before and I accidentally hit the clr cmos button on my z68 extreme 3 gen 3 mobo. After that, when i press power, the computer turns on for a second (proven with fans starting) then turning off and repeating. I can make it boot once with pressing clr cmos but after that, problem continues after i turn it off. I have tried to unplug and clear cmos again, then replugging but problem persists. I have tried to update bios but no difference. Switching from IDE to AHCI or RAID only gives me a blue screen then restarts.
