Weirdest PC Problem u will ever see...

[Anyder]

Ok, so its 2nd time this happened to me, so i tested it a third one, and it also happened.
When i was ingame taking pics of Mos Nemado, PC Crashed as i pressed 3 time, the number 6 (666)
In other words, PC Crashes if i press ''666''
Then PC restarted, and said Windows Had a Problem, and if i wanted to report it. (I did)
Does anyone know what the hell is going on ?

Oddly I too have been plagued by strange occurrences when using my old Mac keyboard on the PC.
When pressing a particular button (possibly Caps-lock) the player list appears and cannot be dismissed forcing me to ctrl+alt+delete out of the game.
On other occasions it has caused freezing or crashing to the desktop.
