Everything about the screen works fine, rarely use the touch option. But now I have small vertical lines showing up all over the screen. Pictures that have dark colors in it, the lines are green. Pictures that have white in it, the lines are purple.

Is this a video card issue?

I can be the cause, however, vertical green and purple lines can be a sign of improper polarization of LCD panels.  Poor VGA connections can cause this.  Worse yet, the screen may have a loose connection inside and may be going out.  Good luck in finding the fix!

Thanks for the submission!

I suppose since it's an all-in-one machine, I'll have to take the backing off and see if anything is loose?

I would avoid taking the making off as that often times voids the manufacturer's warranty. Your best bet (if it is still under warranty) is to take it to Geek Squad / Customer Service at your local Best Buy. If they can reproduce the issue you've been having, they'll determine via the vendor agreement whether it needs to be serviced or it can be exchanged outright. Without Black Tie Protection, Gateway may charge for parts and labor depending on their warranty limitations.

Best of luck.
