[SOLVED] Have to cut power and reboot pc

[Kalwb]

When I play Europa Universalis IV my pc without warning will just make the monitors go black and I have to cut power and reboot it. This is a game I should be able to run easily. I need help because I really enjoin the game and I haven't been able to play it for more than 30 mins at a time.

to have a look what the problem could be:
run userbenchmark.com and post the http link of your result, e.g. https://www.userbenchmark.com/UserRun/28977730

which power supply are you using? brand and model
