Recently my graphics card has been acting strange i will be playing a game and it will start to lag real hard i check my frame rates and they drop from 55fps to 2 fps out of no where. I will drop all my graphics to the lowest settings and it will still run at 2fps.. I restart my computer and the issue goes away temporarily.. Now i realized if i lightly tap on the side of the PC, when i have huge lag spike and frame rate issues, that everything goes back to normal the card cools off out of no where and i can resume my game. What the heck is going on?
