Various possibilities. Check cable that connects between the motherboard and screen - sometimes the end connectors work loose.

Always pop back and let us know the outcome - thanks

If the cable itself is OK it could be the screen or (less usual) the graphics module.

Sometimes tapping with something like a end of a pencil can reveal a poor connection somewhere (symptoms come and go with tapping in a particular area). Also see if it the symptoms change when moving the screen back and forth.

Applying freezer (from Radio Shack) to suspect areas such as the graphics module can also reveal things - watch the screen for changes.

Always pop back and let us know the outcome - thanks

I ran diagnostics on the graphics card and found that there was a problem connecting to the laptop

So it's a dell notebook screen? Can you connect an external monitor to see if it displays the same problems?

If it's using shared ram (or dedicated ram that's removable) you could try swapping in different sticks. For anything beyond that you'd probably have to tear the whole thing apart and even then might not find anything easy to fix.

The obvious thing to try is a different graphics card, can't understand why you haven't tried that already.

If the problem remains even with a different graphics card, almost certainly it means the monitor is faulty.

Your first post said "I have a customer's computer". Now we learn it's a laptop.

That immediately makes some of the replies irrelevant (including mine), owing to bad or incomplete misinformation. Words fail me.

"Yes and it does but not as much"
I think the point I would make here is that it still does it" so its not the monitor. All that has changed is the manifestation of the same fault. It seems to put the graphics card (or module) at the top of the likely list.
