Do you get any display output at all (like pre-boot sequence screen)? Otherwise you could try to use a different port on your GPU. Also try to trigger manual input search on your monitor after starting up. I have a monitor that likes to get stuck on a not connected input and doesn't recover from that until I specifically tell it to look for new connections xD.

it works, tried diffrent outputs, but now i saw that the cpu fan dosnt want to spin at ful speed, can it be a problem with the powersupply?
