Unfortunately, you have get it to boot first before you can flash back with your motherboard.

Perhaps unplug the power and remove the CMOS battery and let it sit over night and then put the battery back in, plug power back to it and then see if it fires up.

That has worked for others in the past]]> Wed, 23 Dec 2020 10:13:15 +0000 https://forum.asrock.com/forum_posts.asp?TID=17559&PID=82436&title=bios-update-wont-boot#82436 https://forum.asrock.com/forum_posts.asp?TID=17559&PID=82425&title=bios-update-wont-boot#82425 Author: Matthewb21499

I tried booting up with 1 stick of ram after clearing the cos and it didn't boot. How do I flash back to v. 4.20.?]]> Wed, 23 Dec 2020 02:28:58 +0000 https://forum.asrock.com/forum_posts.asp?TID=17559&PID=82425&title=bios-update-wont-boot#82425 https://forum.asrock.com/forum_posts.asp?TID=17559&PID=82417&title=bios-update-wont-boot#82417 Author: ThreeDee

unplug power and then hit and hold power button for a few seconds to discharge all residual power from your setup .. clear cmos and pull one stick of RAM out leaving only 1 stick in the A2 slot.

Power back on and see if it boots up. If it does, flash back to v. 4.20. If it doesn't ..swap RAM sticks and try again.

On the 2 x570 motherboards I have .. the newer BIOS's with Ryzen 3000 series .. RAM speeds/capability have been horrid/worse]]> Tue, 22 Dec 2020 18:57:12 +0000 https://forum.asrock.com/forum_posts.asp?TID=17559&PID=82417&title=bios-update-wont-boot#82417 https://forum.asrock.com/forum_posts.asp?TID=17559&PID=82388&title=bios-update-wont-boot#82388 Author: Matthewb21499

I updated the BIOS for my Asrock b450 pro 4 to version 4.50 today and my pc will not boot. I was updating the bios to get my ram to run at the advertised speed. When I try to boot the fans and light turn on for about 10 seconds and then stop for a second and then tun back on over and over. Does anyone know how I can get my computer to boot?
