Hi, ps2 problems

[johnnybgood]

Well, last year around christmas I sent my ps2 version 7 off to norcalmods to get done, and everything has been working great until recently. Whenever I stick in my backups and all that it will play them, but it starts to skip and the cd drive makes noises like it is skipping, and the game freezes, and I know this is probably bad, but when I hit the top of the system(not to hard)it goes back to working. I'm wondering if this means that my laser is going weak or whatever? I have a matrix infinity. If my laser is going weak then this sucks, cause my backup was a backup of my brothers final fantasy x game and I was enjoying that....thanks for any help.

I was wondering if maybe I should try to clean the dvd drive?
