Old Vista Pc does not start?

I got an older laptop from the attic and it won't start.

Just do "Start Windows normally" (arrow down and then Enter), if you haven't made any hardware changes that shouldn't pose any problems…

Go to normal start, he doesn't just do it Enter for jump start (recommended) PS. By the way, that's German. There was a time when you had to do something like that alone and sometimes in English without I-net and it worked. Just think logically.

I've already tried it but it didn't work either

Have you already tried the jump starter?

Indeed
