No matter what game it is I try to launch my computer turns off and goes to black screen. This is a fairly used pc but not too old either, and it just started doing this now.. My specs are: i7-6700k CPU, MSI GTX 1070 GPU, 16gb G.Skill Ripjaws DDR4 2400 RAM, Enermax 450W PSU, and a MSI Z270 Gaming M3. I don't think the problem is an overheating issue as it never was before. Please help.
