I have a Lenovo Y510P ideapad with an Intel Core i7-4700MQ, a GeForce GT 755, and a Intel HD Graphics 4600. This laptop has ran the games I want to play good for years. A couple months ago it suddenly started roaring every few seconds and freezing my game. I downloaded a program that tells me my laptops temperature and with a game running it said that the GeForce GT was at 153 degrees Fahrenheit. Is overheating the problem? And if so what caused it randomly and how can I fix it? Also when I look in task manager at details it says that my GPU is jumping between 89-100% usage. I sat my laptop up to a fan and got it down to 119 degrees, it was still doing the same exact same thing and freezing my game. Any help is appreciated.
