For the last couple of months my 80gb PS3 randomly beeps while playing games. It seems to be completely random. I'm always online, I usually play CoD online and notice it almost everytime I play now (I have also heard it while watching Netflix). Sometimes it is a quite beep & sometimes it is a loud one. It doesn't seem to effect the system at all but I am worried that there is a problem. I keep it clean and plan on backing up the System just in case. Can anyone help or have any info?
