Hello all, I am a happy owner of a 2006 MBP 1.83Ghz CD. It served me very well in these 5 years. However, since about 6 months the display shows some random weird artifacts, graphic corruptions like large chunks of browser windows distorting, or horizontal lines of weirdly coloured pixels and so on. I tried to clean install but it did not help. I guess this might be the graphic card saying bye-bye? (It's an ATI RadeonX1600) Or could it be dust and perhaps an internal cleaning could fix this? Thanks for the feedback!
