Ps2 laser working like crazy

[Dustpuppy]

I noticed that my ps2 struggles abit on some backups I have..
The worst one is The Urbz. Backed up on Ritek G04 disc.
Tried it first and that disc just took forever to read and constatnly lockups in the game. Tried again and that one works better but still some lockups.. and the laser you can hear working like nuts from time to time.

I noticed this on Leisure suit larry too.. Ok, no lockups in that game but that laser was working very hard on that game too..

I know, my system is getting old.

You think that a good clean of the lens can help?
or will I need to start checking up the value on pots?

*damn* why does stuff like this alwas happen when there is no way to afford a new ps2...
