    HD radeon 6800 black screen

      Hi

       

      I've been away for a while so I didn't use my computer for a while, like one year and a half. I use a W7 Pro x64 and my graphic processor is a Raden HD 6800.
      Prob is, when I turn my computer on, it starts, normally, blabla and then BOUM "No signal", the screen is black and I can't manage to get back the video.
      If i turn it off and on again, I have a bios sound code ; 1 long 2 short
      And that's all! I can't tell more because I can't use my computer at all and have to use this 8years old laptop
      In the small window of time that i had given before the screen turns off i tried;
      -booting in safe mode; no better
      -do the microsoft updates; no better
      -uninstall the graphic drivers; no better
      -reinstall them; no tried yet... next boot.


      What I think could be temperature issue? But the fans turn, i cleaned the dust, it seems allright to me...
      Btw i use a HDMI and the screen is a Iiyama Prolite E2407HDSD, maybe i should update its drivers too
      Any idea how to solve it? It's not easy to do anything since I can't see my screen more than 1 to few minuts...

       

      Thanks
