Hello, I've been having trouble getting this card to work. It boots up just fine and I'm able to access windows xp. First time I booted my computer with the card in place everything went fine. I was watching a movie with vlc media player and the movie froze with the screen. I was unable to get the card to boot with anything showing on screen after this event. The computer crashes...screen becomes frozen. Then I'll remove the card from agp slot and replace. Then attempt to boot but I'm able to get any screen view at all during boot....I can't tell if the comp is booting at all since I can't see anything on the screen. Sometimes the card works just fine and other times I can't get my computer to boot with screen views. But if I replace the 7900GS with my Gainward 7800GS my 7800GS card works every time without fail. This is my normal usage gpu...Bliss 7800+. So Since the one time I was able to boot successfully into windows with the 7900GS I checked the idle temps and found them to be a tad bit high (52 degrees Celcius). I thought maybe the old thermal gel was affecting the card's ability to work. So I decided to take apart the card to apply new high quality thermal compound. But I've removed all the parts/screws to the metal cover and the screws on the backside that hold the HS to the gpu. All the screws are removed but I still can't get the heatsink loose at all....it's like it's super glued to the GPU. The only thing I can think of is maybe I need to remove the 3 screws that hold the fan to the Heatsink? Anybody know hot to take this card apart in order to remove old thermal compound and replace with new thermal compound to reduce idle temps? Pictures would be of great help. I tried to find a hands on review of the card where they take the card apart to reveal the various components such as the gpu and bridge chip, but I've been unable to find any hands on reviews which show picture of the card being disassembled to identify the gpu, etc. Any help would be truly appreciated. I don't want to use too much force and damage the aluminum HS. I thought about twisting the HS to get it to come loose from the GPU but have yet to try for fear of causing damage. How do I get the HS removed from the GPU?????
