Fatal Error: System Chassis Intruded!
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?
