I have a gateway laptop. It had windows vista on it. Recently I decided to reinstall the OS, but this time I put on a retail version of windows 7. The problem now is that whenever I shutdown the laptop, the lcd screen shows diagonal scrolling lines (like the ones you used to see on a tv that was not properly tuned to a station when it used rabbit ear antennas).

The LCD dcreen works fine otherwise so could it be that I installed a version of windows for which there were no drivers? But then again if a driver is not found, device manager will show a yellow exclamation mark, but there is no exclamation mark in device manager, so all device drivers have been found.

So then why is the lcd acting like this at shutdown.

Hi shashman,

What you are most likely experiencing is a driver issue upon shutdown. Since it is only at shutdown it can most likely be disregarded as an anomolie that should not cause any issues longterm.

But, as I myself would also find this quite annoying and want to get rid of it, ( read "fix it" ), if you could give me a model number for your laptop, I would be more than willing to see if there is a more up to date driver for your video.
