After i successfully joined a random server it seems that my mouse and keyboard are disabled for some reason. I cant look around, i cant move, i cant even press escape. Nothing works. The only way to shut down the game is to ctrl+alt+del and kill the process.

You can look up the crash dump reports and the dxdiag here:
