    A slow computer isn’t always one to replace.

    Before buying a new PC, it’s worth understanding the source of the problem: a slow drive, insufficient memory, an unstable Windows, unnecessary software, poor settings or ageing hardware.

    ✓
    A diagnosis prevents bad decisions. Sometimes an optimisation or an SSD is enough. Sometimes a repair isn’t worth it. It’s good to know before spending.
    ✓
    Slowdowns often have a specific cause. A long startup, a full drive, old software, stuck updates or insufficient memory can slow a PC down significantly.
    ✓
    Clean work limits the risks. Before any major action, you have to consider the data, the access, the backups and the overall condition of the machine.
    Possible services

    Practical solutions depending on the state of your computer.

    Every job depends on the diagnosis. The goal is to offer a useful, clear solution suited to the value of the machine.

    01

    PC diagnosis

    Analysis of the symptoms: slowness, errors, difficult startup, noise, overheating, black screen or unstable behaviour.

    02

    Windows optimisation

    Software cleanup, unnecessary programs, startup, updates, basic settings and performance checks.

    03

    SSD, RAM & components

    Replacement or upgrade possible depending on compatibility: SSD, memory, basic components and tailored advice.

    04

    Installation or reinstallation

    Clean installation of Windows and Linux, initial setup, drivers, essential software and preparing a computer ready to use.

    05

    Data & backup

    Copying, transferring or recovering data where possible, depending on the state of the drive and the technical situation.

    06

    Advice before buying

    Help choosing a suitable computer: personal use, work, studies, performance or gaming PC.

    Office & gaming PCs

    Diagnosis for standard computers, laptops and gaming PCs.

    Every use has its constraints: work, browsing, studies, gaming, heavy software or simple everyday use. The diagnosis takes the real use of the machine into account.

    01
    Laptop or desktop PC Analysis of slowdowns, errors, storage, memory, Windows and the overall condition of the machine.
    02
    PC gaming Advice and diagnosis on performance, components, storage, RAM, temperature and configuration as needed.
    03
    New PC setup Preparation, basic setup, possible data transfer and installation of essential tools.
    Workshop & diagnosis

    Concrete, clean work, explained clearly.

    The goal isn’t just to open a computer or replace a part. First you have to understand the problem, protect the data and offer work that makes sense.

    Laptop diagnosis and repair Diagnostic

    Assessing the state of the machine

    Checking the symptoms, components, performance, storage, temperature and overall behaviour of the computer.

    Computer SSD and RAM replacement Upgrade

    SSD, memory and optimisation

    Replacement or upgrade possible depending on compatibility, real use and whether the work is worth it financially.

    Computer test bench and repair Intervention

    Clean work and a clear decision

    Every job should stay understandable: what was found, what was done and what to watch afterwards.

    i
    Important: a repair isn’t always the best option. If the cost outweighs the value of the machine, the advice should be clear: optimise, replace a part or consider a new computer.
    Common problems

    Simple symptoms, but sometimes different causes.

    The same apparent problem can have several causes. That’s why a clear diagnosis matters before replacing or reinstalling.

    Performance

    Very slow computer

    Long startup, software that freezes, a slow browser, a full drive or an ageing machine.

    Windows

    Errors or instability

    Error messages, stuck updates, crashes, drivers or strange behaviour.

    Hardware

    Need for an SSD or RAM

    Performance improvement possible depending on the machine, its age, its use and its compatibility.

    Decision

    Repair or replace?

    When the repair cost is too high, it’s sometimes better to invest in a more suitable machine.

    Our method

    A clear approach before any repair.

    The goal is to understand the problem, explain the options and avoid unnecessary work.

    01

    Description

    You explain the symptoms: slowness, errors, startup, screen, noise or the software involved.

    02

    Diagnostic

    We check the likely causes and the limits of what can be done.

    03

    Proposal

    You get a recommendation: optimisation, repair, replacement or another solution.

    04

    Intervention

    The work is carried out according to what was agreed, with care for the data and access.

    05

    Clear feedback

    You know what was done, what was found and what to watch afterwards.

    Is your computer slow, unstable or frozen?

    Describe the problem, the computer model and the symptoms you’ve noticed. You’ll get clear initial guidance before any work.
