Hardware Diagnostics Overview

Basic Information

Hardware Diagnostics are necessary for any computer that may need warranty service or a mail in repair. The manufacture will require a detailed description of the problem and serial number. The problem presented or described by the customer must be reproducible by the technician working on the machine. Error messages are very helpful.

When a client describes an issue with their computer, a full diagnostic should be run to try and determine if other components have failed as well.

It is essential to run a hardware diagnostic to rule out any failed devices when a system is experiencing apparent hardware failures. If the system passes the hardware diagnostics, then the installed operating system, corrupt or missing drivers, or even a virus or malware infection could be the cause of the problem.
