Thank you for the suggestion.
I had no idea how to reinstall a driver, so it took a while (I had to research), but I got it done. Unfortunately, it did not correct the problem.
I should also note that my wife has been playing these games trouble-free for years, until just recently.
Any other suggestions would be appreciated.
EDIT: I'm sorry, I neglected to mention: I saw no entries listed as an error in the event viewer for yesterday. As yesterday was Sunday, my wife did play her games for some time, and had the incident occur at least 3 or 4 times.
