So I just built a brand new gaming pc, and there was a black screen on the monitor because I didn't plug it into the graphics card and instead on the IO shield. I decided to turn the pc onto safe mode but then I realized I plugged the hdmi into the wrong place. I fixed the graphics card issue but my pc is still in safe mode. After I log into the computer and try to type in the bottom left box to turn safe mode off, the keyboard doesn't work. I then tried going to update and security but the tab just crashed. Could anyone explain how to fix this in easy steps because I am sort of a newbie to pc building.
