Hello, this is my first time on this forums so I don't know what all I need to provide. Basically I have a very strong gaming computer that can run basically every game on max settings with extremely high FPS and no lag. The game I am hooked on right now is League of Legends (Not a very demanding game) When I would play League I would get 200+ FPS. I was on a different computer for only five days, then I was able to hook this one up again. Now whenever I get in game I only get 40FPS. I don't know what happened and I have no idea how to fix it. I have already checked to make sure my video card drivers are up to date, and all the windows updates are done..

I was playing games on it and they were working as good as they always did then I shut it down like normal, and everything was fine. I had to box it back up and store it in my room for five days. I was able to hook it back up this afternoon, I had to update league of legends, and I went into a game and saw the FPS was low. I then checked and updated my video drivers, and windows. Also I want to clarify it isn't just league of legends that I am experiencing low FPS in. I tested it on several other games that normally run at 100+fps every time.

I dont think that would have happened because I am extremely careful when boxing it back up, but I tried a reset anyway, and it's still at only ~40 FPS when I normally get over 200.
