Nice but
Replaced my old motherboard because thought it was the reason for my pc not posting but wasn’t it. Still haven’t figured out what my pc actual issue is but all in all once I get it running I can actually say if I like this board or not as you can see in the picture that it powers up but not getting any kind of display picture on my monitor I’ve tried everything including new power supply memory motherboard only thing left to try is a cpu. Checked all wiring as well
