Bluescreen on disableing the Lan connection.

Good day!

My problem is the following. I was using the computer like always this morning, browsing the web, when suddenly i lost the connection. First i checked the page of the router (connection to it was fine), and it showed that there are no problems with online connectivity. So i decided to test disabeling and reenableing the Lan adapter/connection. Upon disabeling it, the pc froze, and a bluescreen showed up.
