it could be any of the pullys, start by taking off the belt and spinning them each by hand to see if you can hear one of them squeak, also make sure they all spin smoothly, any that squeak or do not spin smoothly are going bad and need to be replaced

you can also spray some wd40 on the belt while its running (watch out for he fan while its running) underside is the best.. if the noise stops then its your belt.. the belt can make the noise very easily if its getting water dripped on it by a failing water pump. keep an eye on your coolant level and operating temps for a while.. make sure your not leaving a puddle when you park..

If you replaced the belts several times and later on it starts to squeal, I would recheck your belt alignment to all the pulleys and make sure it is tracking straight. An off set pulley of belt not sitting properly in the grooves will cause this problem. Worth checking into. By the way, Goodyear belts suck, they stretch out too easily. I would replace belts with one made from Gates.
I recently had this problem and funny enough it was the water pump. For some reason (I did not really understand) the water pump was kind of shaking (screw loose). This was causing a vibration on my serpentine belt, which was causing the squealing... no matter what else I changed/fixed. In the end it started to heat up, got the water pump fixed and no more squealing noise.
I have had this same on going problem! once the squeeling started that was it... i changed the belt...that didnt work so i changed the pulley wheel... that didnt work. Then one morning i woke up and the truck whent from squeeling to squeeling and knocking! my tensioner got bad and was knocking from left to right so i put on a new automatic tensioner; the truck squeeled for a couple days then started to only squeel for the first 30 min or so that it was running. four days later my wife was driving my truck and the belt snapped off and got all tangled in the fan and surrounding areas. i came home put on a new belt and now its squeeling and knocking. this knocking isnt from anything visible it sounds as if theres something getting knocked around by the fan or as if some one is doing different jiggs and tap dancing under my hood. i have been told that the knocking is from the water pump being miss aligned... you can see the belt trying to come off the crank pulley then slip back into place then try to come off and slip back into place etc.... all the other pulleys seem to be fine... so now im going to replace the water pump and hope for a this to be over......... i will let you all know the out come
check your coolant levels.. the water pump may be going bad.. if not check for signs of something else in the drive train going
power steering- makes alot of noise when you turn
Alternator- makes most noise when it first starts..
