So my problem is that when I am playing a mild to intensive game I will alt+tab out to check my cpu temps and after that my computer is slow to open task manager and will not open my game back up,also, I cannot navigate task manager. When I finally do get it open it says my cpu is at 83% and I am guessing that my problem is the CPU's fault the specs of my machine are:
i5 4690k at 4.3GHz running at 50 degrees celsius MSI GTX 760 4gb 8gb of patriot viper ram SAbertooth Mk1 Mobo
