some blue screens apeared on my computer

[<RJMC>]

one yesterday when I was using the PC like allways and other today when I turned on the PC

I did what the pc asked about some restauration thing and such

should I do something like burn files to a DVD in case something bad happens and all my data get erased?

Did it have to restore the windows installation? Back up just to be safe. But you can keep running windows as is and see if it doesn't come back.

Or did it give you the prompt to 'delete restoration data' or resume? That would be from a failed hibernation. You can disable hibernation and won't give you the error.
