Stuttering and FPS loss

Hi there, I recently got back to playing LoL after a few years away, however I noticed lots of random FPS drops so I updated my drivers using the Nvidia GeForce programme, however now I'm experiencing similar FPS drops and the game sometimes stutters, by which I mean when there are lots of minions on screen or spells etc the game freezes for half a second or so making it virtually unplayable, I don't really know much about computers so any advice would be great. I have tried lowering the graphics to a minimum (I used to play on about medium settings) but that doesn't help Copied these specs from the GeForce progamme: GeForce GT 755M Driver version 4.17.71 Intel Core I7-4700MQ CPU @ 2.4GHz 15.91 GB Ram Thanks, let me know if you need any more information, as I said I'm not great with computers so apologies if I come across as a moron. I'm beginning to feel like perhaps I need to uninstall/reinstall drivers but that might not solve it. Any advice is appreciated.
