FPS drops all of a sudden

[Dobre12]

I guess my 2 year old gaming laptop might be strangely dying. It's an ASUS ROG GL752vw. Those are the specs: Intel Core i7-6700HQ @2.6GHz, 8GB RAM, Nvidia GeForce GTX 960M (4GB VRAM) and it's basic 1TB HDD @5400 rpm. For whatever reason since about 2-3 weeks ago when i'm in a game (games i used to play before having no such problem) my fps start dropping after some time (about 2-3 minutes in game). I firstly thought the laptop was full of junk files and i did a fresh install, but nothing changed. I have bumped up all the video settings to "Peeformance Mode", still nothing happened. All my drivers are up to date. Anyone know what might it be? PS: I am sorry if I posted in the wrong thread, I have no idea where to post this.
