So I just bought a 1700$ Alienware laptop, not from futurshop but from Dell Online.

First 3months it was perfect, fast..no problems at all. Suddenly 5months after purchasing the Laptop i've been recieving Extremely low FPS too what I was getting, too the point I have to put GFX at low in games, shouldn't be happening.... not at all

I thought it could be internet, but no it's not.  I'm hoping if you guys have any ideas too what could be causing this? is this a issue i'll have to bring in, if so i'm thinking a reformat would prob be the key to this solution and wondering how much that runs by you guys.
