I got a 9800Gt the other day and it isnt working the way it should be doing. I dont think its getting enough power, is it possible that the power adaptor (plugs into video card then into the 2 power cables) only one of the 2 connections is working? would it disply an error or run at all if this was the case?. Also dont know if this will help or not but when i start the pc up the fan is really loud for 1 sec and the same when shutting down. Any info would be great i'm going crazy trying to fuguire it out.
