Wondering if anyone could offer any help with this motherboard I have acquired. The board apparently had a BIOS update and then wouldn't POST. I have tried several USB Bios Flashback attempts and also removed the BIOS chip and reprogramed it with a CH314a. Both haven't done changed anything. The board turns on the CPU light turns on then off. CPU gets hot like normal. If RAM or CPU removed then the corresponding light will light up. However the VGA and BOOT lights will never light up.

The B450-era motherboards seem prone to failure. In my case, what looks like bad MOSFETs.Last edited by RJARRRPCGP; 05-19-2023, 07:35 PM.ASRock B550 PG Velocita
