hardware(power supply, deteriorating motherboard and fluctuating electric
voltage) are causing one way or another this reboot with no user
intervention. this frequent reboot you're experiencing are indications that
your box will soon become a paperweight. as for what you can do, you can
transfer your drive to another box with the same bios configuration, it
should work and you should also backup the contents of that box.
