Game crash on launch

Hi my game wont launch from the Blizzard launcher, and keeps crashing to desktop and the occasional BSOD this has been happening for 3 days, Diablo III and CoD Warzone same thing, im using Console Discussion as it wont let me post in Technical Support

Your description of the problem is way to vague. Is there any error message you get?

This is probably a driver problem or hardware problem or something. Without more information impossible to tell.

If it 2 diffirent games not working, the problem is definetly not the game but your computer.
