Reasons Your [link|https://www.askprob.com/lenovo-laptop-shut-down-suddenly-how-to-fix/|Laptop Suddenly Shuts Off]
'''Dirty Fan/Overheating'''
One of the first and the most likely reason your computer or laptop shuts off randomly, especially when you’re playing a game, is overheating. This is the bane of most computers, especially laptops, since the heat has nowhere to go. It is critical that the computer’s fans are excellent working order to avoid this issue.
'''Hardware Failure'''
Another common reason for a random shut down of your computer is a hardware component failure, which is not unheard of, especially on computers that have been refurbished. If you’ve recently added any new hardware this is the time to remove it to see if the shut down issue goes away.
'''Overclocked CPU Or GPU'''
If you have enabled overclocking on your computer, it may cause your computer to become unstable when used for more intense activities like gaming or video processing. This problem can be a tough one to verify.
Your best bet would be to ensure that overclocking is disabled on your laptop or PC and then see if that stops the laptop randomly turning off incidents.
'''Outdated, Missing Or Crashing Device Drivers'''
Often, the problem with a hardware component causing issues is not the hardware itself but the accompanying driver. Incompatible drivers can cause all sorts of problems. If you’ve tinkered with your operating system or have changed drivers on your computer, this too can be troublesome. A driver crash can always completely shut down a computer.
'''Computer Virus'''
A more rare cause of a computer shutting down randomly can be a computer virus. Some computer viruses will actually shut off your computer, and then turn it back on.
These viruses are usually activated by a certain thing you do on a computer, whether it’s a keystroke or opening a particular program. To make sure you have your best defenses up against viruses, make sure you’re running a great background anti-virus program like Malwarebytes, and that you regularly update the virus definitions and scan your computer.
'''A Faulty Charger, Battery Or Power Supply'''
If you’re a gamer and your laptop shuts off randomly while you’re playing a game at the usual performance setting, chances are it’s your charger/power source.
Most devices come with specific ratings of the chargers that are meant to be used with the device. Using a lower voltage or higher current adapter can cause your device to not work properly and even shut down.
'''Enabled Fast Startup In Windows'''
The Fast Startup feature is aimed to reduce the booting time of a computer after it has been shut down, but it can cause Windows 10 random shutdown issues. Having this feature enabled on your computer, Windows will close all the applications and log off all the users just like it would do for a normal shutdown.
However, before the shutdown completes, the current system state gets saved in the hibernation file. When you boot your PC, Windows doesn’t need to load the kernel, system files, and drivers again. Windows reads the hibernation file to refresh the RAM and significantly reduces the boot up time.
'''A Lack Of Service'''
Though computers are usually sturdy, they may at times require proper maintenance. Without getting a service, laptops may run into overheating, performance and even battery problems.
Get your laptop serviced by a professional to eliminate most of the issues related to your laptop including the computer keeps shutting down problems and any other performance issues.
