Please bear in mind that if your system runs at a temperature that the processor doesn’t support to prevent damage to components, the computer shuts down or reboots if it senses an overheating issue. The system might reboot every few minutes until the problem is resolved. This often occurs if your system CPU is over-clocked (sped up past the recommended speed limits). The BIOS usually reports if a thermal event has occurred.
I hope this can help.
