Guild Wars 2

Everytime I pull up Gw2 launcher I am able to log in and when I press play my computer will do one of three things; Blue screen and turn off, Disable my main monitor but leave audio from the character select, and completely disable my main monitor and “blink?” and flash on my secondary, as if you are minimizing and maximizing something very fast, resulting in me having to turn off the computer because I cannot pull up the start menu nor the task manager.
I have not changed anything but my secondary monitor in the past 5 months, I have uninstalled my drivers, re-downloaded them along with DirectX(Only because I once was able to abort the program and I tried running another game, but got a “Direct3d” error, so might aswell of tried"
I have tried everything I know, somebody please help my lost cause!
