Laptop "Soft" Shuts Down Randomly

The Problem:

My laptop started to "Soft" shut down randomly when NOT in safe mode starting in Mid-October.  I am not able to stop or abort the shut down process.  When in Safe Mode w/ Networking, it does not experience this issue (I posted this discussion from safe mode).  It definitely seems that when the computer is doing something more intensive it is more likely to start shutting down at that very moment.  Once I start to get the shut downs, it occurs much more often and it can start to occur even on the login screen before I log into Windows 10.  My friend suspects this is a Software, not hardware issue because it does not kill the power immediately or BSOD, and does not occur in safe mode.

Note: Although it would be considered a "Soft" shut down, it does shut off rather quickly...I would say always in under 15 seconds from when the Shut down screen is first displayed to me.  When this happened with Discord open, not only could I not open it again after restart due to file corruption, but I was not able to reinstall Discord either.  I had to use a separate uninstaller program to remove the files before I could reinstall Discord.  When I tried to uninstall Discord from Control Panel --> Add/Remove Programs, it said it could not uninstall because it does not exist on the computer.  My point is that the "Soft" Shut Down I am experiencing is aggressive and kills all open applications fast.  It does not display that "Not Responding" screen I am used to when telling the laptop to shut down.

The Full Story:

1. Back in Mid-October, my laptop started to randomly enter the shut down screen while I was working.  I think this is being caused by either a Dell, Intel, or Windows update, because I never had this problem in the past.  This started to occur after both a Windows update and an Intel drivers update (both were updated on the same day).
2. At first I thought to make sure I had all the latest windows updates.  I did.
3. I then checked all the drivers I could find.  Everything was up to date that I could see.
4. I then performed a system recovery by holding the power button when the Dell startup logo comes up 2 times, then a menu appeared to do this.
5. I found that after performing system recovery, I was able to use the computer for up to 1 to 3 days before the random shut downs started to occur again.
6. In order to fix this issue once and for all, I decided to back up all my files on a network drive (I have 2 computers), and perform a clean reinstall of the Windows 10 operating system.  I accessed this feature by holding the power button 2x during boot again the same way I did for getting to system recovery.
7. After reinstalling windows, I started to add some of my old programs and files again thinking all was well.  Everything worked fine until I tried to Download a game on Steam with Discord open as well.  Then i got the dreaded "Soft" Shut Down screen again.  Then a few objects took flight...
8.  I decided to give safe mode a shot again.  I ran that same download in Steam inside Safe mode, and was able to finish the download overnight without any shutdowns.  It has now been over 30 hours in Safe Mode without any "Soft" shut down as I type this message.
9. I have not tried this yet, but I got my windows product key and have also received a Windows 10 installer from my friend to try clean reinstalling that way instead of from the on-computer menu.  Please let me know if you think I should try this.  I have to start over either way right now.

Please Help

Please offer any suggestions that you think I should try to fix this.  Sorry for being long winded...I just wanted to make sure you have all the details to help me get through this.
