"COMMON ISSUES WE FIX"

Expert Diagnosis & Professional PC Repair

Hardware Diagnosis & Repair

When your PC won't power on, crashes randomly, or displays error codes, the problem is usually a failed hardware component. We systematically test every part of your system — motherboard, PSU, RAM, GPU, and storage — to pinpoint the exact fault. Once identified, we replace the failed component with a quality part and fully stress-test before returning your machine.

Symptoms:

  • Laptop or PC won't turn on or no display output
  • Broken laptop screen or faulty hinges
  • Random crashes, freezes, or blue screens
  • Dead laptop battery or charging issues
  • Beeping sounds or error codes on startup

Virus & Malware Removal

A virus-infected PC slows to a crawl, bombards you with pop-ups, and puts your personal data at risk. We perform a deep scan to identify and remove all malware, adware, spyware, and ransomware. After cleaning, we install proper security software and optimise your system to prevent reinfection. Your files and data are preserved throughout the process.

Symptoms:

  • PC running extremely slowly
  • Constant pop-ups and browser redirects
  • Unfamiliar programs appearing on desktop
  • Files encrypted or locked by ransomware
  • Antivirus disabled or cannot be installed

SSD/HDD Upgrade

The single biggest upgrade you can make to an ageing PC is swapping the old hard drive for a solid state drive. Boot times drop from minutes to seconds, programs open instantly, and everything feels snappier. We clone your existing drive so you keep all your files, programs, and settings — or perform a fresh install if you prefer a clean start.

Symptoms:

  • PC takes several minutes to boot up
  • Programs and files slow to open
  • Hard drive making clicking or grinding noises
  • Running out of storage space
  • Disk usage stuck at 100% in Task Manager

RAM & Component Upgrade

If your PC struggles with multiple tabs, freezes during video editing, or stutters in games, a RAM upgrade can transform performance. We assess your current configuration, identify the maximum supported memory, and install compatible modules. We also handle GPU upgrades, PSU swaps, and other component replacements to keep your system running at its best.

Symptoms:

  • PC slows down with multiple programs open
  • Games stutter or lag during play
  • "Out of memory" errors appearing
  • Video editing or rendering takes too long
  • System feels sluggish despite SSD upgrade

Windows Installation & Setup

Whether you need a clean Windows install to fix a corrupted system, an upgrade from an older version, or a fresh setup on a new build, we handle it all. We install the latest Windows version, configure all drivers, apply security updates, and set up your accounts. If needed, we migrate your files and programs from your old installation so nothing is lost.

Symptoms:

  • Windows won't boot or stuck in repair loop
  • Constant blue screen errors (BSOD)
  • System corrupted after failed update
  • Need to upgrade from Windows 10 to 11
  • New build or new SSD needs OS installed

Overheating & Fan Repair

Dust buildup, dried-out thermal paste, and failing fans are the top causes of PC overheating. An overheating PC throttles performance, crashes under load, and can permanently damage your CPU or GPU. We deep-clean your system, replace thermal compound with high-quality paste, repair or replace faulty fans, and ensure proper airflow is restored throughout the case.

Symptoms:

  • PC shuts down during gaming or heavy use
  • Fans running loud constantly at full speed
  • CPU or GPU temperatures above 90°C
  • Performance drops after 10-15 minutes of use
  • Visible dust buildup in vents and fans
