Computers perform best when they receive regular, professional maintenance. The installation and un-installation of software, hardware, and drivers often leave remnants behind in your registry, resulting in a tangle of unused applications, broken drivers, and incomplete and empty command signals. This mass of confusion slows down your computer and if not addressed promptly can lead to serious problems such as computer freezing, programs not responding, and system crashes.
