After doing so, I rebooted, and I went back into the TrackIR software, had a look around, (Didn't change anything) and it froze my PC again, exactly the same circumstances as before. This happened another 4-5 times until I have up, lasting anything from 1-20 minutes before it crashed.
I then ran Arma II without TrackIR on, for 2 hours playing as I normally do, I then closed, opened TrackIR, the second I opened Arma II my PC froze again...
I would be amazingly grateful for any help over this matter, I'm really starting to get worried.
