The Windows 7 operating system suddenly reboots during use.
The cause of the problem is Windows 7 is set by default to automatically restart the operating system after a system failure.
To turn off automatic restart on system failure, follow these steps:
You should cancel automatic restart. If you reboot after every system failure, then you won’t be able to see some error messages. At ” Start ” -> ” Computer ” -> right click on ” Properties “, and then tap ” Advanced system settings “.
In the Advanced options of the system context menu, click ” Settings ” under Startup and Recovery .
Under Startup and Recovery, uncheck ” Automatically restart ” so the system will stop automatically restarting. Click ” OK ” after unchecking the check mark.
