THIS IS INTERESTING. THIS IN MY OPINION IS SOMEONE HOOKING UP THE BOX OR CPU TO ANOTHER DISPLAY DEVICE. NOTICE THE MONITOR AT TOP IS IN STANDBY. IT COULD BE IN DUAL MONITOR CONFIG. BUT THIS IS NOT BY MISTAKE. A MSG TO SOMEONE..
IF U LISTEN U CAN HEAR TWO DEEPS FROM THE PC'S SPEAKER.. could possibly indicate an attempted denied login

2 beeps could be a post error but code could be one of several outputs inclusing access denied to bios by password
ibm possible post errors
183 System halted; password is required
184 Bad power on password
186 Password protection hardware error
187 Serial number error
189 Too many incorrect password attempts
do one have a time of post or sauce for the video posted to fbi site?
