Alright, luckily I still have my old PS at my dads' house so next week I'll hook it up and try it there and even though the discs are brand new I'll still get a cloth like you said and clean it just to make sure. My brother also has to go out and get Dust-Off for his keyboard so when he does that I'll just use it to clean out the all the dust in the PS2 like Miko... or Not Miko said? I haven't been here in so long so I don't know what happened to your name.
I don't know if this would change anything but could it be more the discs because after I beat the boss and the screen goes blank I still hear the motor & disc running inside.
Anyway, I'll just do what you two have said. Thanks.
