I bought a pc a few months back and it run no problem. Yesterday I noticed that the BIOS need and update, being as the version was 1807 and the latest was 2806 or something like that. So I updated the BIOS and now my pc won't move past the Asus start up screen, the additional issue is I cant access my BIOS. I've swapped my keyboard to a different port, removed everything except the mouse and keyboard, removed the on board battery and let the pc drain. The board is Asus b450 prime plus. I'm extremely frustrated. No amount of button bashing is doing anything, please help!
