I've just installed Windows 7 on my Dell machine. Everything works fine except that there are one or two lines on the screen. The line is so random and I am sure that it's now the monitor problem. The graphic card is NVidia GeForce 7600. I replaced the default driver with the driver from the manufacturer and it didn't help.

When I change screen setting, the line goes away for a while and it comes back in different location. Sometimes an app window has the line and if I move the window the line follows with the window.

What can I do to fix it?

Thanks.

Sam

The lines are always horizontal. And I've already tried to change refresh rates. –  Sam Kong Aug 2 '10 at 6:11

It might be that an older card cannot work correctly with the very demanding Windows 7.

Some suggestions:

  • If Aero is on, I would suggest turning it off.
  • If you have the Sidebar, turn it off
  • Look for a video driver among the optional Windows Update downloads

If all fails, this thread discusses all sort of solutions, going from overclocking the video card to flashing its firmware.

But I would first try another and newer video card, to see if this would solve the problem.

harrymc is probably correct but,

try changing the monitor resolution (not just the refresh rates) to see if the lines go away at lower or higher resolutions - if they do its your graphics card - get a new one
