PC stuck after 2 minutes

My HP computer, after working well some years, got the following strange behavior:
After log in, I could start 1 or 2 applications, than I could not start anything anymore, not the task manager, nothing else, and the computer did not react for a shut down command also.
So I set my HP as retired, took a MSI, restored a backup of the HP and started to use it again. But today the MSI shows the same bad behavior.
That finally means that I have a problem with the operating system. I just can not fix it, because I can not start any trouble shooting.
Does anyone have an idea what kind of problem it may be and how to solve that?

Hello

So you can not get into safe mode?

In safe mode the most things work well.
But I still do not know the reason for the bad behavior in normal mode, so I can not avoid that.
