Is it a beep or is it a grinding? There's a chance that the tracking arm of the laser is off, although giving the laser a really good cleaning can work wonders. Not just the top of the laser either, take it out of the system, remove the black cover from the laser, lift the lens, and clean underneath it. Be very careful with that of course, since there's a LOT of sensitive little bits in that laser head.

However, as I recall, the dual gear PS2s are 2003 models, which are pretty much dead in the water when it comes to needing to be fixed; and be careful with the metal bridge holding the laser rails in place since it's very easy to bend out of shape, and then it doesn't do its job very well (or at all for that matter).
