I've had problems in the past with my xbox360 freezing on me, I concluded it was the GPU overheating. I removed the heatsink from the GPU and removed the reminints of the thermal pad on the cores. I applyed thermal paste on the cores and left the remainder of the thermal pad on the GPU heatsink. Reassembled and everything worked perfect for a few months. One day while I was playing it froze again with the red checkered screen. Thats the same screen I've seen before so I knew it was the GPU. Only this time when I reset the console I got the 3 red lights. I've checked the codes and it has to do with some vague hardware failure. I know its the GPU so I removed the heatsink again only to see that the remainder of the thermal pad that I had left on cause I was being stupid had gotten all over the GPU. Now its like melded onto the little bridges that are scattered all over the GPU. Any ideas on what solvent I can use to eat away that thermal pad without damaging the bridges? Also a q-tip is too thick to go in between the bridges. Any help would be appreciated. I've read carburetor cleaner works but just wanted advice before i went ahead and did that. thanks.
