I updated my asus p87zz v-pro to the latest bios 1504. It fixed some issues I was having playing guild wars 2 and actually corrected the crashing issue I was having. I got my pc oc'd to a little under 4.7 with ease and want to try a little higher. The issue is, I can't get into my bios. I tried mashing del the bios button, holding keys to get error when booting , unplugging monitor, etc...The pc is running great but this not being able to enter the bios can't be good. I have searched and searched but can't find a solution .! Desperate for advice, thanks in advance.
