Shutdowns can be caused by many things. If you have your pc setup for automatic updates, some updates require a reboot and will do that automatically. Normally you can prevent that from happening by changing the settings from automatically updating to notify me first before updating.
The shutdown can also be caused by the cpu overheating. Your computer will automatically shut down to protect itself.
Shutdowns can also be created by a infected computer. Malware can cause this.
With out further details, such as what you were doing at the time of the shutdown it's difficult to say why your system is shutting down.
I can say that normally if its a update your system will shut down and reboot, not always, but usually.
Not a lot of help but additional information is really needed. What you are doing, brand of pc, if you have loaded new software or hardware, as much information as you can provide would help.
Sometimes, just goggling you problem on line with the make of the pc will help you find the answer you are having. Many times the problem you are having has already been addressed and a solution provided.
