I was overclocking my PC within windows 8 because I am unable to access the bios (Common problem in windows 8). I restarted my PC so the overclock would take place and the voltage is too low. I am aware of a way to get into the bios through advanced boot up settings but for some reason the option for booting into my bios isn't there. Does anybody know of any way I can boot into windows or the bios to change my settings? This is urgent.
