Could try with reinstall / update the motherboard chipset drivers to the latest. Which motherboard model&make?
it does not have an internet connection (for fear of viruses), so I can't connect to update drivers etc.
Make a backup of the stuff you want to keep safe. Enable its internet connection, update drivers+SP3, latest fixes and SW you need. Disable internet connection.
