I bought new computer 1 year ago and everything went really nice until 10 days ago my graphic card fan stops working at times. At first I didn't know what was going on but I decided to open my case and start playing some really required game like WatchDogs and I noticed this. The fan stops working only when I play games. I updated my drivers but that didn't solve anything. I don't know why this is happening or how to fix it. I can tell when the computer is going to shut it self down because of overheating so I quickly alt+f4 my game whenever I see its going to happen. And I stare at the fan hoping that it will start working on it self again. I try to push it with my fingers but it wont continue. Only after 5-10 minutes pass I can move it with my fingers and it will start spining again. What do I do?
