Serious error your computer has been recovered from

Can anyone interprete those pics, please?

I have old machine end XP OS.

I notices severe slowness of the computer, one by one features are dropping out, I san’t watch videos on twitter and most of videos, Youtube often warns me on non-updated browser but I am mostly working on Word so I suffer in silence,

Just a half an hour ago when I turned on desk top I saw this message

Your system has been recovered form serious error.

I clicked on to see what error it is and I attach 2 pics.

My desktop can drop dead any minute, right?

Is it so serious?
