Hi guys, I have an Asrock z77 extreme4, and I must have brushed against the CLR CMOS button. Now I have error A2 which I have figured out means I need to switch from IDE to AHCI and a completely black display. I resetted the jumper and unplugged my main video card to use the onboard graphics and I have still gotten absolutely no visual feedback. How do I get the display to start working so I can boot BIOS? Kind of a noob at this stuff... Appreciate it.
