After Effects' preview stays black all the time

[Stefan32643557tm3v]

Hello.

After Effects on a colleague's laptop stays with a completely black preview of the composition all the time.
I've worked with After Effects for 9 years and I've never encountered this problem before. I tried so many things, but the preview of the composition just stays black. Nothing shows up. The laptop is with the latest version of AE. I also downloaded an older version from the creative cloud, but it's the same problem.

When you create a new composition the preview is just black and whatever you place inside the composition it remains black. After Effects worked fine the previous week, but he said after the weekend this problem occurred. I tried so many things I found by googling the problem, but nothing works so far. Any idea what the heck is going on?

Thank you in advance.
