For about 5 years now we have had a Lexmark X73 connected. All of a sudden it started having problems. We first noticed the problem when we attempted to print a map from Mapquest. Instead of printing a map, it printed several pages of "computer language." I contacted Lexmark. They instructed me to completely remove it from my computer and then reinstall. When I attempt to install, as it is going through the process, the computer shuts down; then restarts. Any ideas on what to do next?
