B340M Pro4 3 beeps pause 3 beeps

My PC stopped displaying anything. When I boot it gives 3 beeps, slight pause and 3 beeps. No display and fans continue to run. I took out my 2 memory sticks cleaned the contacts and reinstalled them. Same issue when trying to boot up. Any ideas as to what to try next? I did try booting with only 1 stick in A2 with no luck also.

Sounds like a display related issue, either it's no longer detecting your GPU or
there is an issue with your monitor or display cable. Try another cable as well
as a different display output if possible.
