Windows 10: None on my programs are staying open, they just close randomly.

Hello,My pc has started to just close any program I try to open, i try opening any program like the minecraft launcher for example but it closes itself seconds later, my anti virus software wont stay open long enough for me to do anything, but programs like word and steam will stay open... i can't find any documentation anywhere for this.... someone please help cos i'm thinking i may need to do a fresh install of windows...Thanks.

Programs Closing

I have a similar issue, but it seems to be all programs. I have not found one yet that stays open. Closure seems to be random in terms of activity; I tried disabling the trackpad and it might have helped a bit but still happening. Ran Panda antivirus and Malwarebytes as suggested by Michaelvas17, nothing found. Also tried running all programs full screen, that didnt help either.
This Dell laptop model is apparently borderline for Win10 - initially I could not run anything, turned out it was forcing an alternate display (which I didnt have attached, but adding one gave me access to fix!).
While typing this, I am seeing a different but probably related behaviour. Firefox is not closing, but I keep hearing a ping and characters no longer register until I reset the carret to this text box.

 

Windows randomly closes

My windows will randomly just close at odd times. Any suggestions?

 

Comptuer Closing open programs

My windows 10 computer is constantly closing my open programs without warning. I could be in the middle of typing something and the program just randomly closes. It usually closes them when the programs get anywhere close to slow. This problem also happened
on my laptop that was very slow and I just recently upgraded to a desktop. This problem is very frustrating. I don't know much about computers so if this is a simple setting, please tell me. Thank you!
