I am a recent mac convert and have loved the experience so far. I bought a used macbook Pro (2.16GHz) - which may not have been the right thing to do in hindsight... Anyway, for the past 3 months or so, I sparingly used my Macbook but my experience was awesome in all respects. I use it in dual boot mode with Windows XP and Leopard installed in 2 partitions. Recently, out of the blue, my MBP started showing tremendous amount of flicker and grainy picture. I am not being picky at all. It is impossible to work with the amount of flicker and graininess that I am experiencing. It lasted for about a day and then went away for about a week. Then suddenly it has re-appeared and now it would not cease. This affects both operating systems - windows xp and macos (leopard). Can anyone relate to my problem? Any tips that can help me recover my investment would be greatly appreciated. As it stands now, I am going to have to buy a new laptop if I cannot fix this problem. I do not have any support on my MBP either. Thanks much..
