Service Computer Diagnostics

Computer Diagnostics

If your computer is not working correctly, suddenly shuts down, fails to start, freezes, restarts, or shows other unexpected behaviour, our Computer Diagnostics service can help identify the possible cause of the problem. Computer issues can be caused by many different factors, including faulty hardware, overheating, power problems, memory issues, storage failures, software errors or incorrect system settings. Instead of replacing components without knowing whether they are responsible for the problem, an initial diagnostic inspection allows us to investigate the issue and determine the most appropriate next steps. This service is intended to identify the suspected fault and provide a clearer understanding of what may be required to restore the computer to normal operation.

When Do You Need Computer Diagnostics?

PC diagnostics may be required whenever your computer begins behaving differently from normal or is unable to operate correctly. This can include a PC that does not turn on, turns on but does not display an image, randomly restarts, shuts down during gaming, freezes, crashes or becomes unstable. Diagnostics may also be useful when the computer is noticeably slower than expected, produces error messages, experiences repeated blue screens or has problems detecting installed hardware. In some cases, the cause of the problem may be relatively simple, while other faults can require further testing or replacement parts. The purpose of the diagnostic service is to investigate the issue before additional repair work is carried out.

• The computer does not turn on or start correctly.
• The PC turns on but does not display an image.
• The computer randomly restarts or shuts down.
• The system freezes, crashes or shows repeated errors.
• The PC becomes unstable during gaming or demanding workloads.
• A component may not be working or detected correctly.
• You are unsure what is causing a problem with your computer.

What Is Included in the Computer Diagnostics Service?

Our Computer Diagnostics service provides an initial inspection of your PC to help identify the suspected cause of the reported problem and determine what may be required to restore normal operation. We investigate the issue based on the symptoms you have experienced and carry out the appropriate initial checks on the system and relevant components. Depending on the nature of the fault, this may involve checking the computer's startup behaviour, installed hardware, temperatures, stability or other areas related to the reported issue. Once the diagnostic process is completed, we can explain the suspected cause of the problem and advise on the recommended next steps, including whether further repair, replacement parts or another service may be required.

How Does the Computer Diagnostics Service Work?

To use the PC diagnostic service, you arrange the service with CompHub and provide the computer for inspection. When submitting your PC, it is helpful to describe the problem and explain when it occurs, such as whether the issue happens during gaming, when starting the computer or after the system has been running for a certain period of time. This information can help us focus the diagnostic process on the reported symptoms. We then carry out an initial investigation of the fault and assess the condition and behaviour of the relevant parts of the system. Once the inspection has been completed, we will provide information about the suspected issue and discuss the available options for further work if required.

What Is Not Included?

The Computer Diagnostics service covers the initial investigation and identification of the suspected fault. It does not automatically include the repair of the computer, replacement components, hardware upgrades, Windows installation, software setup, data recovery or any other additional work required to resolve the issue. If a repair or replacement part is required after the diagnostic process, this will be treated as a separate service or quoted separately where applicable. In some cases, further testing may also be required to confirm an intermittent or difficult-to-reproduce issue. The diagnostic service helps determine the most appropriate course of action before additional repairs are carried out.

Who Is This Service For?

This service is suitable for customers who are experiencing a problem with their desktop PC or compatible computer and are unsure what is causing it. It can be particularly useful before purchasing replacement parts or arranging a repair, as identifying the suspected cause first can help avoid unnecessary work or replacing components that are not responsible for the issue. Whether your computer is completely unable to start or is experiencing occasional crashes, shutdowns or performance problems, the diagnostic process provides an initial assessment of the fault. After the issue has been investigated, you can decide whether you would like to proceed with any recommended repair or additional service through CompHub.
