A user asks you to troubleshoot his Windows 7 workstation, which is behaving erratically. He has recently purchased and installed a new graphics adapter, and ever since then, he sees occasional wavy lines in the display. You run Device Manager on the system and note the manufacturer, model, and version number of the device driver for the graphics adapter. Then, you check the adapter manufacturer’s web site and discover that there is a new driver available for the adapter. After downloading and installing the driver update, you restart the system. The system appears to start normally, except that the graphical interface has been replaced by incomprehensible noise. Because you can’t see the display, you can’t work with the system. What should you do return the computer to an operational state?
