I have recently installed a Ryzen 5 5500 in my Gigabyte ab350 gaming 3 motherboard. The cpu fan will run for 10 seconds then turn off. I do not get BIOS , only Black Screen.
I have updated the bios to latest version and I also updated incrementally to avoid issues. The only update I did skip was bios version f25. My Ryzen 2600 still works fine when installed.
I have tried taking out one of my 8gb ram sticks and no joy. I have also reseated both.
I'm not sure what to do? Can anyone help with this?
Have you watched the Diag. LEDs to see where its freezing or looping, or tried removing CMOS battery for bios reset ?
You will need to install at least bios F.40 as that gives 3rd gen Ryzen support.
Read your post again and you have already updated.
Check the pins on the CPU, make sure none are bent.
1. If you are using Q-Flash Utility to update BIOS, make sure you have updated BIOS to F31 before F40
2. Before update BIOS to F40, you have to install EC FW Update Tool (B19.0606.1 or later version) to avoid 4DIMM DDR compatibility on 3rd Gen AMD Ryzen™ CPU
