Problem Ps3

Hi,I have just had a problem with my ps3.As i was playing it makes the sound as you put in your game..Then if you continue to play without stopping the sound quality will screw up.The cause might be...My ps3 is next to a wall so dust builds up alot:confused: I have got to do an update but im scared if it takes to long and does this.Is it overheating if you have a solution could you please send to me it would be a great help :thumbup:

Let's think, maybe try cleaning the input ports and if it helps. Also if you think if your console could be overheating, think about moving to another spot if possible.
