Aurora r5 boots with no display or sound

Ny aurora r5 wont start up.

After a leaving the computer in idlemode overnigth, the computer wont start again. When I Press the powerbutton, the fans starts spinning and so on, but nothing else happens. No display. I cant shut down the computer, only if i hold down the powerbutton for 5 secs. 

I have tried to remove all cords, including powercord. Held Down the powerbutton for 1 minutte. Nothing.

At one point (NOT to begin with) it startet with a two beep sound, but that ended when i tried shifting the ramblocks around.

My display seems to be working ok
