Windows 10: my new Dell laptop randomly shut down

I bought a Dell G3 15 laptop a month ago, and it keeps turning off randomly, it's not often, in a month it turned off 4 times but it's annoying. I found this event:I am sure this event is related to turn off, how should I solve this?any Idea?

My NEW Dell laptop keeps restarting randomly (Windows 10)

About 3-5 times a day, my brand new Dell laptop just randomly shuts down while I am working and restarts itself immediately. It is very quick, but also very annoying when I am working with a customer and it does this. It is not doing this in a specific
application, but very randomly, and I can't seem to find a pattern.

 

laptop randomly shutting down

I have a gateway laptop w/ amd turion 64x2 processors,windows vista. I use to be able to play games all day, do 10 things at once and my laptop was fine. All of a sudden i have ran into the problem of my laptop randomly shutting down. At first it was just shutting down when i was playing video games (games that doesn't even have the greatest of graphics and that i played ever since i had laptop which has been for about 2 years); ide say i would be able to play about 5-20 min and randomly would shut down. Then i stopped playing video games on this and now just download music and playing music and if i am downloading music and playing music and converting music it will shut down on me. Seems to keep getting worse and worse, like today i was just browsing the internet it it shutdown on me. I did get a blue screen the other day as well, first time it has happened to me on this laptop. If anyone could tell me what this could be i would greatly appreciate it.

Another note: If i unplug my laptop from the recharger i can usually play until the battery is dead, but it will make my computer real laggy and choppy so its not even worth to do when playing games.

 

Laptop randomly shuts down after latest Windows 10 update

Since the latest update of Windows 10 my computer decides to randomly shut down after every couple of minutes. First the screen goes black, then the sounds stops and after quite a while the power also goes down.

Obviously I though of cleaning the fan with a big vacuum, as suggested on My Windows 10 Computer Randomly Shuts Down . However, after doing this, the shutting down goes even quicker. I cannot even properly log-on before the shutdown takes place.

What should be my next step?

Ps. The computer is quited aged (roughly 3 - 4 years). The battery is dead enough such that I always need to have it plugged in an outlet. It might just be "done for" but I'm hoping to revive it for just a little bit more.
