Owning a PC means having to deal with a multitude of errors that you or you may not understand. This is true if you’re just an average computer user who rely on their computers for day-to-day use whether at work or at school. Computers contain drivers within. These drivers are files within the system that make sure that your PC’s operating system smoothly communicates and works well with your hardware devices (these are devices usually externally connected like a mouse, keyboard, printer, scanner, etc). If you own a PC, you probably own at least one of these hardware devices. Sometimes, these drivers fail and this is problematic for the users. External devices can no longer function well because the communication between the device and the PC’s OS is somehow cut off. When this happens, this would be shown to you as Code 19 Error.
