Gosh, I'm a dummy. I don't even know what a "heat sink" is!! Never heard of it. Just got a new laptop about 1 1/2 years ago & had the guy from Geek Squad (Best Buy store) install everything. Unfortunately, I was also supposed to get an hour or hour & a half tutorial from him on how to use the new system (Vista) but I had come down with the flu that morning & was basically lying on the couch trying not to groan too loudly. Boy, I was sick. I couldn't sit up.

I asked him to reschedule the tutorial but he told me it would cost me $250 for an hour!! Needless to say, I'm winging it here.--Suzy
