Hello Martin,

Most likely this kind of defectives occur due to your notebook's cooling system not functioning properly. Below guide will help you to troubleshoot the fault.

  • Check whether fan spinning (Note: Fan not spinning all the time and it's randomly start by thermal sensing )
  • Check whether laptop get over heating near exhaust.
  • you can visually inspect whether dust blocked you exhaust .

if any of above observed you can clean the heat exhaust and test the speed. let us know if error remain same. we can help you to next step troubleshooting 

I think you need to optimize Windows computer. Some programs in the background may cost ram, and the junk files also will make your computer run slowly.
