There’s vertical lines on my iMac screen. I’ve heard it’s the graphics card but I want to see what you guys think before buying anything.

@shrek420 - Likely a bad display, you need to be careful as the pressing on the back side can damage things. I would plug in an external display to check things. This model offers a Mini-DVI connection on its back with an adapter you can plug in a VGA display.
