Well it's probably a hardware issue. Most likely it's either your monitor or your GPU or the cables between the two.
You will first want to make sure your DVI video cables are properly connected. You will first want to shut down the computer and the monitor and unplug the power cords. Make sure the DVI (the cable connecting the monitor to the computer) cable is securely connected to the monitor and the computer. The thumb screws should be tight and the connectors should not move or wobble in their sockets. Make sure the cable itself doesn't have any obvious breaks or sharp kinks. If you cannot get a secure connection or if there's any damage to the cable you will want to replace it. If you happen to have another DVI cable around that you know works, you might try replacing it as well.
If this doesn't resolve the issue, the next step is to determine if it's a issue with the computers graphics processor and video memory. You can rule out the GPU by restarting the computer in safe-mode. If you're using Windows, safe-mode can be accessed by pressing the f8 key while the boot screen (the screen that has a manufacturer logo) displays before Windows loads. While if you are running Unbuntu this is done by pressing Left Shift at the boot screen. If you do not have the lines in safe mode, it is an issue with your video card and it will need to be replaced. If you still have the vertical lines while in safe-mode it may be that the monitor is broken and will need to be repaired or replaced.
