Price confirmed before work starts
Memory upgrade
The Lenovo Legion Tower 7i Gen 8 uses standard desktop memory. We check the board’s limits and fit matched modules.
Overheating and fan repair
We clear dust from heatsinks, fans and filters, replace failed fans and renew thermal compound. On liquid-cooled systems we test the pump.
Windows repair and reinstall
The Lenovo Legion Tower 7i Gen 8 shipped with Windows 11. We repair start-up faults, reinstall Windows cleanly with your files kept, and remove malware.
Graphics repair
We diagnose and replace failed graphics cards, and check that the power supply and case can take the card you want before an upgrade.
We also carry out motherboard repair, virus removal on the Lenovo Legion Tower 7i Gen 8, 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
- Dust build-up and failing cooler pumps are the usual causes of overheating.
- Legion Tower and IdeaCentre Gaming desktops take standard graphics cards, but power supply capacity needs checking before an upgrade.
