my PS2 has been making horrible clacking noises and freezing when running games for a couple of years now (it's pretty old). This week it just stopped running games altogether. It doesn't play CDs either, but the noise isn't so bad as with games. I had some idea that it might be an alignment problem, but I really don't know much about the tech side. Also, I took it into a repair shop and it worked fine there, but doesn't work at home. The fan is fine and I don't keep it on the floor...I'm clueless. Any ideas?
