Fatal Error: System Chassis Intruded!

[TheAmazingJordo]

I installed a TV Tuner today, and after the installation (it was kinda tough to get it to sit correct) but after a little moving around, the TV Tuner went in. When I booted up my PC, it went through the Asus Rampaged Formula Welcome Screen before it begins to actually boot up, then it went black and said "Fatal Error! System Halted: Chassis Intruded!" after that I paniced, and restarted the PC. It booted up fine this time, and has booted up fine the two or three times since. Should I be worried? or just be grateful?

I don't know this for sure but maybe when you booted up the first time windows had enough time to find the appropriate generic drivers needed for the tv tuner card and it needed a restart to work.
