Whenever I'm playing any kind of game, my screen will randomly turn black and come back on and say "HDMI" as if my monitor reset. I will get the error message "display driver has stopped responding and has recovered" and everything is a bit choppy for a few seconds after that. On good days it doesn't happen at all but most days I can't even play a game for more than 20 minutes without it happening. A few people I know have told me it's probably my graphics card but I want to make sure before I go out and buy a new one. I have an NVIDIA GeForce GT 740, not the best for gaming but it works well with the games I play. I used to keep my drivers up do date with GeForce Experience but a friend of mine said it was horrible so I haven't used that in about 2 months. Something I did notice was that my CPU usage will randomly jump really high if I tab out of a game. I'm not sure if that's normal or has anything to do with it though. I have an Intel Core i5-4690K Processor. I'm not too smart when it comes to stuff like this so any help will be appreciated. Thanks
