I'll try to mention everything I did in detail in case it helps and since I don't know what is relevant or not...
So this gaming laptop comes with 8 GB RAM and I wanted to get another stick of 8 GB. I look up the same kind that is already there cause I know those usually work best with it, and order it. When I get it, I get into the laptop and install the memory. AFAIK I didn't do anything wrong here. I slid it into the bracket/slot at an angle and then pushed it down to where it snapped neatly into place. I even looked at a tutorial video and did just what they did. Put the square cover back on too.
I then put the casing back on and boot up the laptop. I notice I get a "Scanning and repairing drive (C:)" screen come up, and for like over 10 minutes it was stuck at 16%. Right about when I was going to try to restart it or troubleshoot, it finally went up to 100% and then I get to my usual login screen.
However, when it prompts me for my pin, I notice the keyboard doesn't seem to work. There's no input from the keys I press onto the screen. I then notice the bottom part of the casing was not completely closed flush and one of the screws was at an odd angle; I thought maybe because of that there was some issue with the keyboard. I then corrected this and the noticed now a bunch of random characters were showing up in the password/pin box, like 666666 repeating on and on and on or other random letters and numbers, which I couldn't delete with the keyboard. I decide to shut down and start up the computer again. After an unusually long wait I get to the login screen again, and again typing things on the keyboard makes nothing show up there.
Note that my mouse and click have no problem and can click on things on screen fine.
I then clicked on the On-Screen Keyboard to see if that does anything and a white empty box comes up, with the loading cursor constantly on. It's been 10 minutes and I can't even close or X out of that now.
Could I have really screwed up this computer?? I'm kind of worried here. I had a lot of important data that I didn't back up on there.
EDIT- I found an old USB keyboard that I had in a closet and plugged it in, and that was able to work now. So I logged in. The problem seems to be mainly the (built in) keyboard for now, but I'll see if anything else is wrong.
