Green, horizontal lines on monitor

I turned on my Dell Studio Laptop this morning and everything started normally.

As soon as the Vista screen loaded, though, the monitor was covered in green, horizontal, flickering lines (from top to bottom). The desktop loaded, but the screen was barely visible due to the lines.

After a few restarts, the desktop will not even show up anymore. The vista screen goes straight to black (with green flickering lines).

When I boot in safe mode, everything appears completely normal. No lines whatsoever, which makes me think it's not a monitor issue.

Sounds to me like it could be a problem with operating system files. I would format your laptop and reinstall, if the graphics card had given up or it was a piece of hardware causing the fault, you wouldn`t be able to boot into safe mode with no green lines

Hi birchlore :D
Try connecting the laptop to an external screen to see if the display is the same,
you may need to toggle between screens by pressing the Fn key and one of the F1 to
F12 keys.
Possible causes bad drivers, overheating, bad video chip or bad display ribbon.
The reason you get a display in safe mode is because Windows only installs the bare
essentials(including video drivers) meaning the system is not operating under load
which uses less power and produces less heat, anyhow check the screen and post back.
