I bought a laptop with an Intel core i7 4700mq, 8gb RAM and an nvidia GT840m. I bought this in August 2014. I would play games and have around 30 fps in them, however of recent the frame rate has plummeted to around 7 fps on the exact same settings. Can anyone please explain what is wrong with my computer and a solution to my problem
