Welcome to the forum.
Can you tell us all about your video card/chip, and the installed version of your video driver? The more detail, the better.
I would first check the installed version of the video driver, against the latest one on the nVidia, or AMD/ATI Web site. If there IS a newer version, then download and install that - reboot and test.
Also, Delete the BadDrivers.TXT file.
Sorry but I'm a complete noob at this kind of thing. Could you tell me where to look to find out what driver I am using?
First some Windows 7 64 bit direction to the BadDrivers.txt file which I believe will be your answer, especially if your video card driver proves to be up to date. The information that you were given seems not to be for Windows 7 64 bit. The Windows 7 64 bit path to the BadDrivers.txt file is
Local Disc C
and in the 11.0 Folder is the BadDrivers.txt file that you delete.
Close out of there.
Make sure that you are working with Folder Option Show Hidden Files, Folders, and Drives active so that you can see the complete path.
Then open Premiere Elements and gauge the results.
