ok, so go into BIOS, select the TOOL tab and then select "Asus Overclocking Profile". See what you have. Selecting any of them, if you have any its going to revert any tweaking you have made but it can change things for the better on things you didn't know had been changed or forgot you did. This normally helps when you a have been messing about with settings and lost your way. BUT you may have nothing. Also take in mind it could make things worse i suppose but im just covering my ass. Use at you're own risk but I've found it helpful a few times and at the very least you know this function exists and can use it in future if you save a few profiles before delving into some mad tweaking session.
