    refurbishment of a 10-year-old PC

    Successful renovation of a 10-year-old PC, except for the 2 drives which were newer. But computing, certainly of quality and with improved performance, remains quite expensive.

    As expected and described

    With the BIOS update, AMR Ryzen5 3400G processor recognised immediately.
    CPU temperature < 40°C.
    The paper documentation provided is minimal and difficult to read. Available on the DVD provided or on the internet.
    To install the fan, the mounting system must be removed because the chosen processor is screwed in place.
    Screwing in place is easy if the motherboard is completely flat. Be careful not to lose the back plate and position it correctly
    before screwing it in place.
    The CD provided is from 2020. The Win11 installation automatically installed everything on a 256GB NVMe M.2 PCIe SSD.
