robinb1: To follow up, I fixed my green screen issue related to the integrated graphics card on my Toshiba laptop. At first I was trying to "update" the drivers by downloading the latest drivers from Intel and installing those. It told me it wouldn't allow that and I had to download the latest custom drivers from the Toshiba website. Those drivers where old & didn't fix the issue.
I ended up "replacing" the driver by first uninstalling my current driver in Device Manager. This reboots the computer and makes the graphics driver to be a Standard Microsoft Driver. At this point when I downloaded the latest drivers from Intel and installed them it let me do it and it fixed the green screen issue.
Edit - robinb1 responded in a PM (he is having some GOG forum issues which I hope get resolved soon) that he is using Windows 8.0
