Common Problems We Fix

If your PC is doing any of the following, bring it to us in Belfast and we will tell you what is wrong before you spend a penny.

  • Slow computer

    Long boot times, freezing and lag. Usually fixed with an SSD upgrade, more RAM or a clean Windows reinstall.

  • PC will not turn on

    No power, no display or a dead fan. We test the power supply, motherboard and front panel wiring.

  • Blue screen crashes

    Random restarts and blue screen errors traced back to RAM, storage, drivers or a failing board.

  • Overheating and loud fans

    Full clean, fresh thermal paste and cooling repairs to stop thermal shutdowns and throttling.

  • GPU and graphics card repair

    Artefacts, no display and crashing under load. Graphics card repair, reseating and upgrades.

  • Power supply faults

    Tripping plugs, sudden shutdowns and burning smells. PSU testing and replacement.

  • SSD and RAM upgrades

    Storage and memory upgrades with your files, apps and Windows moved across for you.

  • Virus and malware removal

    Pop-ups, browser hijacks and ransomware cleaned off, then hardened against a repeat.

  • Windows reinstall and setup

    Fresh Windows install, drivers, updates and data restored so the PC feels new again.
