Computer fault finding

PC & laptop diagnostics

When the cause is unclear, proper testing comes before repair. Our technicians assess the symptoms, test the relevant hardware and provide findings and practical repair options.

Common symptoms

When you need diagnostics

  • Computer will not power on
  • No display or startup failure
  • Intermittent freezing or crashing
  • Blue-screen errors
  • Unexpected shutdowns
  • Slow or unstable performance
  • Overheating and fan issues
  • Suspected drive or memory failure
Testing follows the fault

What we may test

There is no honest single-button test that proves every component in every condition.

Hardware

Memory, storage health, power, temperatures and relevant components are checked where applicable.

Software

Windows startup, drivers, system errors and software-related instability may be investigated.

Reproduction

Intermittent faults may require repeated tests or extended observation to reproduce.

Simple and transparent

What happens next

  1. 1

    Book-in details

    Tell us the symptoms, when the problem started and anything that changed beforehand.

  2. 2

    Technical testing

    We assess and isolate the fault as far as reasonably possible with the machine presented.

  3. 3

    Findings and options

    We contact you with the result and practical next steps before additional work proceeds.

Stop guessing and replacing random parts
