In June of 2006 I purchased a new HP media center pc( it arrived in August), every thing was great until November when the Video card fan started making loud sounds at start up and an odd raspy sound after that(sounds like the fan's bearings on the video cards are bad).  I guess the 7600 would rather be a race car or airplane.  I had the card replaced ( Horrible customer service from HP first tier of support ). 13 months later December of 2007 the new video card decided it was a race car as well and exhibited all the same symptoms(HP support lost a life long customer after this tech support phone call).  An now when I turned on the pc this card new for only 3 weeks decides it wants to be a race car. I really don't want to call HP and spend another 4 days on a support call.
