One possible reason for this could be that your computer is overheating and has to shutdown every now and then. I suggest you get it checked by a computer technician.
Also scan your entire system for any viruses or so.
Well also another possible reason is that your computer may have alot of dust clogged up where the air is suppose to get out which causes the hot air to stay in your computer which will overheat and shut down. I suggest you go to a computer technician and let him take a look at it
Yes, it should stop all shutting down actions by your computer if the system is overheating.
Computers don't restart after shutting down. You probably have some setting on your OS which give the computer the command to always reboot. Change that setting.
Reprogram the computer with a new program from the aftermarket.
