You said that I am ok because I have some light on etc. then the board I'd dead its sound like a contradiction!
I said that because I didn't read your first post when you said all the fans were spinning and the LEDs were on etc. Before I read that, I thought ESD may have killed it, now I don't think so. Sorry if it sounded contradictory or unclear for you.

So there se way to test the board before buying an other one?
There's obviously something up with the board if it's running but not displaying anything - unless you have any bent pins on your CPU by any chance? Have you removed and reinstalled the CPU at any time? If so then you may have accidentally bent one or ore of the pins which is preventing the board from displaying a picture.
Are you using a graphics card? If so, remove it and try using the onboard graphics and see if it's any better for you.
If you're not using a graphics card, I'd say the board is at fault. There's not really any way to test it other than maybe to take it out of the case and try running it outside of the case on a book or something just to make sure it's not grounding and making contact with the case in anyway.
