Hi sms1295,
Please try this fix list, which removes the rest of the third-party drivers. It's more aggressive, and I'd not run it without backing up the registry.
- Backup the registry using Acelogix.
- Run this fixlist.txt. Share fixlog.txt.
Note: It removes the Corsair HID drivers and other drivers. I'm not sure if it makes the Kbd/Mouse inoperable. In that case, you can attach a standard keyboard or revert to the previous registry backup via WinRE.
