And, unfortunately, no context, that is, no way to guess what is going on.

 

You can certainly narrow the possible issues.  For example, you can test the hardware, test the software, take a look at any errors (in the Event Viewer, for example).  

 

There are many underlying causes that can cause the computer to shut down.

 

I did not find a computer model  "HP Pavilion 450 G3"

 

There is a mid-level "Probook" business class model that is similarly named:

HP ProBook 450 G3 Notebook PC

 

 

Candidates that cause shut-down include  (not a complete list):

  • Heat - caused by faulty hardware or dirt/dust in the vents and interior of the computer
  • Bad / Failing disk 
  • Operating System - File System corruption ("Windows" is corrupted / bad / having trouble)  - file system errors
  • Malware / Virus infestation
  • One (or even more than one) bad software / program that is corrupted / incompatible

 

It is impossible for you to diagnose unless you know a bit more about what is happening.

 

Suggestions include:

  • Make sure Windows Updates is current 
  • Make sure your computer software / drivers are up-to-date
  • Check the "startup" software list to make sure the software that is starting when you boot / log in is actually software you want started when you boot / log in.  What?  Not every program needs to run every time you log into the the computer - some software should only be started manually and when you want to use it.
  • Run File System checks - see if Windows is aware of any errors / problems
  • Run Hardware Diagnostics - check at least the CPU / memory / disk(s) 
  • Run your security software filter / scans to detect and remove problem files / software
  • Less likely, perhaps worth checking:  Other devices on your network that are interfering with your computer / network connection.  This requires that you understand your network and how to manage the router and the various devices that you connect to that network.  Not sure?  Switch off "other devices" and "just see what  happens".

 

 

For example - some of the tools and software to be considered include:

There are hundreds of articles on the 'net dedicated to "chkdsk".  Use your favorite search engine to find an article that meets your needs and skill level.
