I think the issue might be linked to your external hard drive. Whenever it's connected, the computer tends to keep restarting repeatedly, which feels like a continuous loop of rebooting. The only solution I've tried was turning off the PC without the drive. It's unclear if this points to a Windows system problem, driver issues, or something with the drive itself.
