I built my new PC today with an 8700K, on an ASUS Prime Z370-A. Everything was working fine, I had finished installing all of the drivers, doing windows updates, installing apps etc., when the program ‘ez update’ an ASUS product, notified me that there was still an update for the BIOS. I clicked install, it downloaded, and my PC restarted. It came up with a screen showing the bios and a loading bar like it was updating, but my RGB memory which was being controlled by Aura sync changed colours. After the bios update finished and windows loaded, it was extremely slow. I could open one program, but any attempt to open another would do nothing. Trying to shutdown the Pc would do nothing. Trying to open task manager would do nothing. I thought I had done something in the bios so I reset it to defaults but no change. I also took out the small battery on the MOBO to see if it fixed it, nope. I don’t know what to do anymore. How could the BIOS update screw my PC this bad?
