Windows 10: My PC keeps randomly shutting down then opening itself

No it's not a restart or anything,it keeps happening at random times.
I did not experience this issue until yesterday.

Weirdly enough it also affected my browser,my 'profile' was deleted and I had to make a new one.

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.
