I am running on Windows Vista Enterprise Build 6000. I'm having problems
working my Nvidia GeForce 6800 Ultra 256mb although it was meant to be
supported. I've used all possible drivers , official or unofficial but still
there is no solution.

I try to apply Aero , the screen goes black , No Input Signal is shown ,
cursor appears , freezes and then a blue screen for 1 second before Computer
is restarted. Then I have to disable the adapter from Safe Mode before
entering windows again

When I try to change resolution , again the screen goes black but then
returns to previous state and a bubble says "Display driver stopped but has
successfully recovered".

Of course , I don't have the ability to play any games . The game starts
shows some cinematics at first but freezes at one of them.

I can't even play audio or video files . When I disable the card , the play
normally.

Thanks in advance
