sqeeling sound on start up?

As the subject says. This happens sometimes not every time. Sounds like a belt related problem or a tensioner not sure only lasts a couple of seconds just want to pin point the problem. Any help appreciated.
The car is a GPX auto 97.

I'd imagine its your ps/ac belt mine has started making noise about 4 weeks ago is getting progressively worse the bearing in the Ps pump is at fault in mine there is play in it
