Dell Latitude E7470 freeze and/or Flickering

Hello I have the problem that my laptop freezes very often when I open a program, even after a restart it freezes. I also have the problem that something suddenly starts to flicker (For example, names in the title bar or entire buttons) and the system freezes too. With both of these problems, only a restart or alt-sysrq-k helps and that’s annoying because everything that has not yet been saved is lost.
Here are my system information:

Edit:I made i915.enable_psr = 0 because I had even worse problems before.
Edit:When it freezes I can usually still move the mouse only nothing reacts.
