Desktop and All-in-One service based on technical testing.

A computer that does not start may have a power supply, memory, motherboard, storage or software problem. Because different faults can produce the same symptom, replacing parts without testing can waste both time and money.

We repair desktop and All-in-One computers, restore operating systems, maintain cooling systems and perform compatible SSD or RAM upgrades. After the approved work, the computer is tested for stable operation before collection.

Common faults we handle

  • No power or failed startup
  • Unexpected shutdowns or restarts
  • Windows errors and blue screens
  • Slow operation or storage faults
  • Overheating and excessive fan noise
  • SSD, RAM or graphics upgrades

Technical inspection

What we test before recommending a repair

We inspect power delivery, temperatures, memory, storage, the motherboard and the operating system. If the fault only appears under load, stability tests help reproduce the conditions that cause it.

Work considered after diagnosis

  • Hardware fault diagnosis and replacement
  • Compatible SSD and RAM upgrades
  • Cooling-system cleaning and maintenance
  • Motherboard repair where technically viable
  • Windows and driver restoration
  • Component compatibility and stability testing

Useful answers

Frequently asked questions

Is the initial computer diagnosis free?

Yes. Initial diagnosis at our workshop is free. We explain the findings and cost before you decide whether to proceed.

Do I need to bring the computer cables?

For most desktop cases, the tower is enough. If the fault may involve a particular adapter, peripheral or cable, bring that item as well.

Can I upgrade instead of buying a new computer?

After checking compatibility, we can assess whether an SSD, RAM or other upgrade offers a worthwhile improvement for your system.
