I just flashed an asrock x58 extreme 6 mobo and none of my gpu outputs is working.

I have no idea what to do in order for it to come back. Nor im hoping me turning it off after it succesfully flashed with no visual screen hurt it in any way. (Freaked due to this random event. not to mention you cant turn it off without pressing off button on case) I tried to understand to clear the CMOS but i dont think it worked because I still have a blank screen. Sometimes when i was trying to figure out to work the Dr Debug digits didnt light up but everything else seemed to work.

Any help on this issue would be greatly appreciated as this is my first time building a computer.
