Windows 10: Laptop randomly shuts down to a blue screen saying "Locking"

I tried all the advanced battery fixes like battery action "do nothing" and Link State Power Management turned "plugged in" and "on battery" to off but it's still doing it. Any help would be appreciated.

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.

While I am using my computer doing whatever, my computer randomly changes to a blue screen that says Locking with the windows 10 loading circle for a few seconds and the shuts itself down. I cant find a solution online and its been happening for some time.
