Microsoft Windows 8.1 offered a nVidia driver update a week ago. The driver update specifies the nVidia GeForce FT 610, a relatively older video card.
The system quickly started glitching by displaying black windows, and then started crashing the operating system with DPC_WATCHDOG_VIOLATION. The driver was removed using Microsoft Windows System Restore to a restore point prior to the driver installation.
The next check for updates found the driver update ready to be installed. Remember to right-click on the name of the update to access the context-sensitive menu. This will allow the update to be hidden.
