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

It will get stuck at the CPU LED if there is no cpu installed. If a CPU is installed the board behaves as normal with the CPU light on then going off.Comment

by TwieselHey y'all,
I am currently working on an Asus ROG B450-F Gaming II ATX Mainboard. The board is in very good condition (no missing components/scratches), but when I power it on using a Ryzen 3 1200 and one stick of DDR4, it gets stuck at 1,4A with none of the POST-LEDs lighting up.
I checked all voltages, which are present. The CPU gets slightly warm.
What I did try:
-Resetting CMOS
-Reflashing BIOS (manually and using the flashback tool)
-"cleaning" the socket with isopropyl alcohol
-using several sticks of DDR4 in every slot... -
