Sudden Shutdown of Laptop or pc is like the nervous breakdown. Heat related issues occur sometimes occurs when you put excessive workload on your e.g., playing a graphically intense computer game or editing a video.

In simple words when you want to get more than its capability, your device pushed it by power, and this generates excessive heat inside your laptop, because of which system shutdowns to saves its components.  So before playing with heavy files, upgrade it with necessary Hardware and software.

However this is not the only reason for this problem, but there are other reasons too which might cause sudden shutdown.

Possible Cause:
Virus/ Malware Infection
Hardware Failure.
Overheating

Before  go for detecting the hardware fault you must check your laptop for any infection of virus or malware. Because many malware program cause system crashes.

Windows 7,8,10 have inbuilt security program “Windows defender” which mostly repulse such attacks, but I would advise you to double check with other antivirus software also.

Hardware like CPU Fan sometimes gets weak or permanently stop and not enough to cool down the temperature of Processor. To check whether the CPU fan is running perfectly slow just place your hand near the fan vent if you feel milky warm air then your fan is in optimal condition but if very less effect of air and your laptop is frequent shutting down then your CPU fan corrupts or the thermal paste (paste between heat sink & processor) gets dry. If your fan is not working appropriate than you feel excessive heat near fan on both side top bottom.  If overheating is the problem than follow the below steps

Over Heating: Overheating may cause by many reasons like

Blockage in Laptop Exhaust Vents
Heat Sink clogged with Dust
Heat Fan Malfunctioning
A degenerated thermal grease between the heat sink and the CPU or GPU
and sometimes due to improper ventilation.

So Start by verifying the blockage in laptop exhaust vents, In that case you will locate the exhaust vents which is at the sides of your device. In a few laptops they may be located at the back. Through the years, your computer may additionally accumulate a big quantity of dirt that clogs the air vents in the laptop.

To remove dirt from clogged vents take a can of compressed air upright and spray the air directly into the fan consumption vents on the facet and bottom of the computer. In case you don’t have compressed air, you can use a hair dryer at the “Cool” setting, but remember to maintain a specific distance between your laptop dryer do not operate it more than 30 seconds and don’t use it on hot setting. It may damage your laptop components.

To check whether the Heat Sink is clogged? You have to open the case of your laptop. I would suggest you do not open if you are not familiar with the hardware & components however if you know how to open and a techy type of person then you can do, before that please read the instruction manual to open.

But before you start cleaning you must do the below things.

Before you attempt to do any cleaning, however, follow these steps:

  1. Shut down the computer
  2. Remove the battery
  3. Unplug the power Cord
  4. Ground yourself (Read how to ground yourself)

Now open the back cover & detach the heat sink by unscrewing it and take a piece of cotton with some alcohol drop and gently clean it. Now when you open the back case use a Compressed Can air,  a vacuum cleaner or hair dryer (with cold setting) which one you have to clean the the board also, Be remember that you have to clean the heat sink, CPU Fan and dust inside(where it may present).

Now re-fix all the components to their original fitting but make sure it will completely dry (no cleaning liquid present), turn it on and check for the difference.
