Ok I have gone through so much crap and I am at my wits end with this PC. So christmas of 2015 I built this above average gaming pc. Its got a MSI A88X - G45 gaming motherboard, 16 gigs of RAM, a 970 GTX Graphics card, and NOW it has an Athlon X4 860k Quad core processor of 3.70 GHz. It is running windows 10 pro which was cleanly installed. I need help I cant find out for the life of me why I am getting stuttering on this computer. It used to be just affecting certain games, but now its gone from affect certain games to my whole operating system. If anyone has any idea please help me T.T
