I am running an Intel Core Duo 17" iMac 1G. I got it a little after it's initial release in 06'. The other day on my screen, a strip of vertical pixels turned a light blue color. Today, (2 days later) a second vertical strip appeared. Is my screen going? Or is this something that can be fixed by software, or a long shut of period. I know I'm long over due for my iMac upgrade, but up until now this baby has rocked solid using intense apps and solid computing. Funny enough, I'm also still rockin' an iPhone 1G! It's so upgrade time, but I'm holding out to see what verizon is soon to be offering with an iPhone. We all know it's coming very soon... Thanks for any help!
