Premiere freeze and shot down no warning or error

My Premiere Pro keeps shutting down. There is no specific action that course it, but it happen after some time editing and usual with large videofiles.

It's freezes and shot down. Is it my computer, that is to old? It was working fine before but the shut down began to happen after the summer.

I'v tried "downgrading" to an older version of Premiere, but it dosent help.
