Memory upgrade
The Dell XPS Desktop 8940 uses standard desktop memory. We check the board’s limits and fit matched modules.
Windows repair and reinstall
The Dell XPS Desktop 8940 meets Microsoft’s Windows 11 requirements in most configurations. We upgrade from Windows 10, which reached end of support in October 2025, or reinstall Windows 11 cleanly with your files kept.
We also carry out motherboard repair, overheating and fan repair, virus removal on the Dell XPS Desktop 8940, along with no-picture and no-boot diagnosis, port repair, Wi-Fi and Bluetooth card replacement and data transfer to a new PC.
Notes from the workshop
- Adding an SSD as the boot drive and keeping the original hard drive for storage is the usual upgrade.
- XPS and Inspiron desktops use some Dell-specific parts, including the power supply on several generations, so upgrades need checking against the chassis first.
