When I first bought my PS2, every game downloaded without a problem. But I just noticed about 3 months ago, it won\'t load certain games. Example, when I bought the PS2, I bought NHL 2001 with it, the game worked for a while. But now the game won\'t load up and my PS2 makes weird sounds when I put the game in. I wasn\'t worried with this before because I thought the disk of NHL 2001 was just scratched and wouldn\'t load. But I finally freaked out when I bought Top Gun-Combat Zones about 2 days ago, and noticed it wouldn\'t load up! I returned the disk to the place I bought it and exchanged it for a brand new one, but when I put the game into my PS2. It wouldn\'t load up and made the weird noises I was talking about. I got to the Broswer on the PS2 main menu, it keeps on giving me "read disk error". I don\'t understand what is this problem, if anyone can please help me and give me some suggestion of fixing the problem. If it helps, I noticed that the PS2 wouldn\'t load certain games with blue color disks. The only problem is, Midnight Club has blue color backside and it loads up fine in the system. But like I said before, NHL2001 which has a blue backside doesn\'t load, and so does Top Gun-Combat Zone. Can anyone please help me???
