Join the club. Model 100x Playstations have a habit of developing
skipping problems after being left on for a long time. The reason is
that the power supply in those early models put out enough heat to
slightly warp the plastic on the CD mechanism. This caused the lens to
go slightly out of focus, leading to video that skipped, choppy CD
audio, and abnormally long loading delays.
There are two fixes available to those who don't mind playing around
with their Playstation's innards. The first is to slightly tweak the
lens alignment knobs. A simple overview of this procedure is at
http://www.cyberia.com/pages/mlfink/320.htm. However, note that it is
very easy to screw your Playstation up worse than it already is using
this method, plus it's only a temporary fix: the problem will most
likely come back in the future or the problems will redevelop after
the unit warms up again.
The second alternative is to have the CD mechanism replaced. You can
supposedly take it to Sony and have it fixed for $50, but if your
Playstation has a mod chip, all bets are off. You can also buy a CD
mechanism off the net and install it yourself. A good, reputable place
that people seem to recommend is National Console Support
(http://www.ncsx.com/). I've heard that replacing the CD mech isn't
that hard (two or three cords and some miscellaneous screws), but if
you're an amateur, make sure you keep all the parts and you don't have
any left over. =)
