I run Windows 11 Pro and use Chrome. All drivers and BIOS are current. After a recent hardware upgrade, my system keeps rebooting. I have a Dell XPS laptop, connected to a Thunderbolt docking station. I run ethernet through the docking station. I have an external monitor connected through the docking station. I've uninstalled and reinstalled Norton. Couple of different scenarios I've narrowed down where system is rebooting. VPN seems to be the conflict. I've run hardware diagnostics. Everything checked out fine. Also run operating system diagnostics, all checked out. No issues found. No registry issues. All drivers current.
