Played fine, now monitor says its out of range.

So I broke down and bought the game before I was able to get ahold of a guest pass. I downloaded it and did the tutorial and played some single player maps.

I decided to try some online matches and played two games before it locked up on the screen between matches. The countdown timer stopped but I was able to pull up the menu and exit to the main menu. I went into the options to check what keys did what and without and when I tried to go back to the main menu my screen went dark and little blue box shows up and says I am out of the range of my monitor. First off I didn't even change any settings so I don't know why I could play fine before and why it would just randomly do that.

I could hear my mouse moving over things but I couldn't see them, so I was forced to reboot since I could exit or pull up the task manager and now every time I try to even load the game the same blue box shows up and says I'm out of range and I have to reboot. All of this happened with me not changing a single thing, so what do I do?
