Either the monitor is going bad or the video card is going bad. If you can get your hands on a spare monitor, try swapping it out and see if the lines are still there. If they are, then the problem is with the video card. You'll want to replace the video card if that is the case.
Ram modules can also cause vertical lines on a monitor.It's hard to believe but i have experienced it multiple times.The ram is detected by the system,yet the display is corrupt.If you open up the PC and touch the ram modules the lines go away.This is very rare yet a possible cause and easily overlooked.
The video card could be over heating which causes what you are seeing, lines can also be called "Artifacts". Try opening the side of your case and see if you see these lines. Also, it could be a driver issue, try cleaning out your drivers using Driver Cleaner, and reinstalling the appropriate drivers.
If you have another computer, if the video card is a expansion video card (Meaning you have it in a PCI/AGP/PCI-E slot) try it in another computer to see if the problem persists, if so your card is probably bad and needs to be replaced.
Also check to see if there are any magnets near the screen or hard drive.
