Sorry for not getting back sooner Markus. I'm out of town and away from the internet, almost long enough each day to suffer from withdrawal symptoms...
I'm not sure on Windows 10, but you should be able to get to it by doing that "Search" thingie by the Start Menu, and type in "Event Viewer". In Win8 and earlier, you'd use the "Control Panel", "Administrative Tools", "Event Viewer", or us the "Search" on the Start Menu. Choose the different files that you want from that page. Start with the "Windows Logs" choice, and then probably the "Application" one. Give it a few seconds / minutes to load, and look for errors and warnings there. When you select a message, it will populate the screen with info. If you double-click on an item, it will open a separate window with all the info. You may or may not find anything useful, but stand a real good chance of finding conflicting, and sometimes downright confusing info...
