B450M Steel Legend no POST after bios 2.10 to 2.50

   Hello,

I have B450M Steel Legend with ADM Ryzen 5 2600 (without a gpu core), an Asrock Radeon gpraphics card and AMD 16G memory.

After successful upgrading from 2.10 bios to 2.50 (telling flashing is OK) the mobo now not booting and not showing post, but signalling beep error codes: one short, pause, three long beeps.

I've tried other memory (8G crucial) and other graphics card (nvidia) to no avail.

What happened? What can I do to bring it back to working state?

	That is the code for no GPU detected. Try the GPU in the lower PCIe slot and see if that get's you a POST screen. If not, it sounds like a bad flash. You will need to contact ASRock Tech Support: https://event.asrock.com/tsd.asp Good luck
