Hello,

I just bought the MB today and assembled in the case.
Power is on, fans turning, but the monitor screen is black.

Ihe ClearCMOS at the bottom of the board has only 1 blank/1 pin.
So how do I clear the CMOS knowing that the battery is covered up.

Please help. Thank you.

I read thru the CPU support list and my i5-11400K is not on the list.

Should I downgrade to i5-10400? Have tried all poosible connections and the problem is still there.
