Need computer specialists here - FPS problems

03-40 FPS is what I get while playing on a not so sh**ty laptop. Its really really frustrating to play like this. Today I was at my friends house who has a little better computer but a stable 60 FPS with almost everything set to high while I'm playing on very low I'm not really a computer specialist when it comes to the specs so all of your suggestions will be helpful <3 Also, I've already done some of the steps that Riot made a few years ago about increasing FPS and it helped for the first 2 weeks then the FPS drops got back...
