So I just got this 2.16 white MB. Originally when you started it up, there were the colored vertical lines on the screen and it didn't recognize a HD. I assumed that all I needed was a new HD, fresh install of Leopard, and to reset the PRAM. The install of a new HD went well but I can't get the lines to go away! I reset the PRAM and changed the display settings. I did a hardware test and it came out clean. Here is a shot of the lines As you can see, this isn't the typical vertical line at start up problem. Is this a faulty graphics card, logic board beginning to fail, or something simple like a cable that may be going out or not connected properly? I've never seen this so please help!!
