Specifically, during "Now Loading" screens in Disgaea. My PS2, which has worked marvelously ever since I got it a few years back, makes rather strained, Dreamcasty (one of the scariest-sounding systems there is. I keep thinking it's going to explode and shoot CD shard at me) grinding noises. They go away soon, and nothing has gone wrong, but it sounds like something on the verge of breaking. Should I be worried about this?
Also, I had a strange thing happen with the controller. The other day, after replugging it in after having had the dance pad in for DDR, the left analog stick stopped working. Everything else worked fine. Pulling it out of the control port and putting it back in solved the problem. Odd.
