I purchased SH4: The Room the other day, and it won't get past this one loading screen about midway through the game. At first, I thought it was the disk because the game is second hand, so I cleaned it. Unfortunately, it still does not get past this loading screen.

My other games have been acting funny too, Burnout 3 randomly freezes, certain DDR songs don't start or skip, and on top of that when I was playing DDR the PS2 turned off by itself. I turned it back on, played a bit more, and it turned off again.

Any suggestions?
