Why wont your ps2 read any game discs?

open the disc tray. then take a can of air with a straw thingy on the end of it. Then blow the aire in to every hole and everything in the disc tray......that always helped for me i thought i was doomed when this happened to me because i putso much work into my ps2 for 5 years but my dad helped me save it .hoped i help good luck :p
