I have an early 2006 iMac which is in almost perfect condition, it is faster than many new computers that i have tried, it boots up quickly and works perfectly. The 17 inch screen however is starting to have the vertical lines issue, i currently have 6 lines in random places on the screen. They don't appear in screenshots. How can i get rid of these? The screen was perfect when i got it in January and i only paid $100 for the iMac. it's running snow leopard and i have upgraded it to 2gb of ram. I love it lol
