It sounds like a bad LCD panel, video cable or the connection. Power on the computer and keep tapping the F8 key then select Safe Mode with Networking. See if the problem appears on screen. You can also choose Low Resolution VGA mode (or something like that) from the F8 menu. That will help determine whether it's hardware or software related.

Try to reinstall your graphics driver and check your screen at different resolutions in safe as well as normal mode.Also try changing the themes and check if random lines still appear.If the lines still appear randomly then its a sign of LCD screen going bad.
