Check to see if you have the latest drivers installed for your model. Go to the Dell web site. DO NOT use any drivers from Microsoft updates.
Do you have any electrical devices near the laptop, like a fan, air conditioner or heater? Try moving it away from them. It may be picking up interference from them.

If this does not correct the problem, you may have a failing screen or LCD cable. The cable runs through or near the hinge. Everytime you open and close the lid this cable flexes. Sometimes they wear through and cause this problem.

Monitor flickers with lines across screen


screen is going bad which is why its flickering and has the lines across the screen. Theres a board behind the lcd and when that doesn't process the voltage properly it can cause the screen to flicker. White lines across the screen means the screen is going bad. At this point unless your monitor is under warranty, go ahead and replace it.

Compaq presario v2000 monitor is having horizontal purple lines that flicker.


Try reloading the drivers, delete the device in device manager and reboot. It should then pick up the drivers and reload them, if that does not work I would suspect the screen is on its way out (flickering normally means the screen or its connection is bad)
