Extremely low FPS error

Hi everyone! Firstly. Have a nice day!
I'm gonna go into as much detail as possible.

I have some fps problems with my laptop which I usually played before.

Normally my game is around 50-60 fps tho, but I accidentally stepped on my laptop (around the word Q to Y section) and my game fps drops to only around 10 fps.

If possible is there any technical way to make it done, everyone? I wanna check it out before having it fixed. If you guys need further information about my lap, I'm gonna post it later

Many thanks!
