My PS3 has been making these strange noises for about 1 month, I don't think its normal or I wouldn't be posting about it. It seems that it only happens while I'm playing the game. So I'm thinking its the BD-Drive, but I'm not certain. It sounds like:
PS3 was the greatest console I ever got. I would of gone to Bestbuy to return it and get a new one, but I bought it from the US and I live in Canada, and the box and receipt are at my uncles house. This noise wasn't coming for the first two months I had the PS3.
