Ive had my PS2 for about two years now. It has always worked perfectly, no problems, and I didnt mistreat it ever. But about three weeks ago, I started to hear this clicking sound when I would play. It soon become louder, and more frequent. Then it said on most games that it couldn't read the disc. Now it wont play any game at all. Im thinking its the CD drive, but I really have no idea. Any ideas?
