I turned my PC on and went to type in my password like usual but nothing happened, i turned 'on screen keyboard' on, and everything on there works accept the letters (numbers, caps lock, shift etc), ive checked to see if nums lock is on, it is not, ive checked filter keys, it is not on. I've restarted my computer 5 times to no avail, the only other reddit post that pops up when I search for a solution says to do everything ive already tried. I even plugged my back-up keyboard in and its the same story. I've had my computer for around 3-4 years and this is the first time I've run into this issue. Is my computer done for or am I overlooking a simple solution? Please help
