Honestly, in my 28 years of life I haven't seen anything quite like this. I recently build my first computer after about 10 years of not building computers. Here are the basic stats: OS: Windows 7 Ultimate x64 CPU: i7-4790K MOBO: GA-Z97MX-Gaming 5 GPU: GTX 970 GAMING 4G RAM: Ripjaws X Series 32GB HD: 120GB SSD + 960GB SSD If you haven't watched the video here's what is happening to me. Many programs (Minecraft being the example program that is affected by this) become unresponsive for a fraction of a second many times over but continue to work after that split second is over. In conjunction with that the same affected programs seem to open a duplicate of itself and then close itself. When that happens any keystroke or mouse click will stay persistent until they same key or button is clicked to trigger the button_up event. I've no idea what's causing this. All the drivers are up to date and everything is correctly installed to my knowledge. I've setup the paging file to go to my larger non-OS/Programs SSD because every time I'd work with Premiere CS6 it would just eat all my storage. This is really the only major thing that I've changed. If you fantastic people have any ideas at all I'd love to hear them otherwise I'm just going to be reinstalling Windows. Also, I'm sorry if this is in the wrong section. I wasn't too sure where to post because it might be a software or hardware related issue.
