Ok so I’ve been having this issue for a week, so everytime my pc loads, passes the startup screen then on to the sign in screen, that’s where my keyboard and mouse stop working. But they work when I open a startup menu in the boot menu. So I tried to look up many things to help my needs to fix my pc. But none fit what I’m dealing with. My pc doesn’t even a a safe mode not even in the boot menu. I even tried with another keyboard and mouse but it’s a no go. I have theory’s what might have happened. I installed a ps2, and a ds emulator to play well ps2 games and ds games but ever since then my keyboard, mouse, controller of a xbox to play cod and other games stopped working. I can’t even install updates not even with driver easy or drivers 8. It’s so fustrating.
