Lagging problem for ps 2?

Question

Hi All, my ps 2 "sometimes-- 1 in 4 chances" stop when loading CG or switching scheme, if it stops during scheme-switching the background music is still on. I've adjusted the degree of laser and also the voltage of it but still it doesn't seem to work. This problem only occur in some games like Final Fantasy X, need for speed, splinter cell 3 and the like, but loading CG in other games(e.g. devil may cry 3, ) have no problem at all. Someone please help....
