Cs:Go Error (config problems?)

[Quentin]

Hello, i have a big problem with cs go and other valve games like tf2 and css:
Whenever i start cs go everything seems normal first until i join a server..
Everything starts lagging and after some time my computer disconnects itself from the internet.. this is in the console:

Ive tried different things like verifying the integrity of game cache files and other stuff
