OK. After it shuts down everything, there should be a few kernel messages
(in green) on the text console. The last one is typically something like:

acpi: entering S5

or similar. Do you see those? Any errors printed there in the last seconds
before it reboots?

This may be a problem with you BIOS/Firmware and it is worth to
check if there is an update available.
