So I installed my D54250WYK, updated BIOS, installed Win7, updated Win7, got XBMC up and running and tuned it to fit my use.
I did all this while the NUC was connected directly to the TV's HDMI-port(with a miniDP to HDMI-cable).
This evening, my girfriends birthday and I was planning on watching a movie on the NUC with the wife to be, so I connected the NUC to the Receiver, the same port as my previous HTPC was connected to, and when I turned the system ON it was all black.. No signal the screen said..
WTF was my first thought, so I disconnected the NUC from the receiver and connected it directly to the TV again, but still nothing..
The power-button remains blue after turning it on, but the NUC never sends a tiny bit to the TV, it sais "No signal".

So this evening I've seen a movie with the lady on my old HTPC while I've had horns growing on my forehead.. WHY IS IT ALL BLACK!!!??
Could it be that the NUC just forgot how to send signals out to the miniDP-port? I dont have a miniHDMI to HDMI-cable, so I cant check that out, so I will try to get my hands on one of those on monday.. But still it is saturday night here, I WANT THE NUC TO WORK, NOW!! :/ (sorry for the capitals..)

Anyone experienced the same thing? Any ideas about what has gone wrong and how to get it right?

BTW: When I shut down the NUC before disconnecting it from the TV and connecting it to the receiver there was a windows update-shutdown, but I dont think that would have any effekt on how/where the NUC sends its signals..? And remember, it doesnt even send the BIOS-text or nothing, it sais only NO SIGNAL on the screen..

So please guys, help the norwegian dumbass out here..

Now I have even tried with a miniHDMI - HDMI cable, still no picture..

Noone out there who has tips? I just cant figure this one out..

Edit: I have restored the bios, during this I obviously got signals from the nuc to the screen.
But when I replug the microSSD the screen turns black again.

Now I'm making a bootable USB to reinstall the win7 from and see if that works.
Do you think there would be any difference if I restored the BIOS with an older version?
