The dreaded 3 red lights of doom

Usually means an overheating problem, had my last one do it and had to be sent back for repair, well it wasn't actually repaired as they sent me back a different console !! Not worried as was lucky to get mine fixed at all as had bought it off Ebay and was around 18 months old !!!!

If it has done it once it will only get worse and seems to do it more if you are online with it.
