I have the slim, black 2nd model PS2. It loads GH1, GH2, GH3, 80's and Aerosmith just fine. It, however, will not play GH5 or Van Halen. The Van Halen game will progress through the memory card load and let you select medium>single>guitar>goes to a loading screen, a computer animation screen, loading again, then freezes. The GH5 copy was brand new and will not load anything whatsoever. I looked online and found similar complaints, but everyone says that the slim PS2 should run them. Suggestions included turning the PS2 on it's side vertical or cleaning the laser with an alcohol Q tip. Someone also said it's because the laser is going bad, but I believe my system is in nrmnt condition with very little mileage.

Any possible fixes? Suggestions?
