What does the PC doctor USB solution primarily focus on?

The PC Doctor USB solution primarily focuses on hardware diagnostics. This tool is designed to assess and troubleshoot various hardware components of a computer system. It runs a comprehensive set of tests to identify issues related to components such as the motherboard, RAM, hard drives, and other peripherals. By performing these diagnostics, technicians can pinpoint hardware failures or potential problems, allowing for timely repairs or replacements.

In the context of a computer's overall maintenance, while software updates, network performance, and security checks are also crucial, they are not the primary focus of the PC Doctor USB solution. The emphasis here is on ensuring that the physical components of a computer are functioning correctly, which is fundamental for the overall health and performance of the system.
