It is recommended that you run diagnostics using the Hardware Diagnostics utility, as part of a regular maintenance plan to validate that the attached hardware is functioning properly.

Diagnostics utility has a physical (as opposed to logical) view of the attached hardware, it can identify hardware problems that the operating system and other online tools cannot identify.

You can use the hardware diagnostics utility to validate the memory, I/O devices, CPU, hard drives, and other peripherals.
