Keyboard broken

A few weeks ago I restarted my laptop and it started making an incredibly loud beeping Sound as if keys were stuck. I managed to log into my desktop using the on screen keyboard but as I double clicked my internet browser around 40 pages popped up so I knew something was stuck. After this, a few of my number buttons stopped working but this didn’t really bother me so I didn’t try fixing it but now it seems like my whole keyboard is messed up. Whenever I press a button its almost as if my return key is stuck. Here is an example of me typing without using the on screen keyboard
