OK, First when was the last time the Belt(s) were changed?
Next - There are 2 pullies - one called an Idler Pulley and one called a Tensioner Pulley. They are smaller pulleys and the bearings can be going bad. To check for this all you need to do is have a can of WD40. Before starting the vehicle spray the center Bolt on either the Tensioner or the Idler Pulley Not Both. Then start the vehicle does it still make the noise? If so turn vehicle off and spray the other pulley the same way and start the vehicle, if noise has dissappeared then change that pulley. If the noise is still there and you have change the belt(s) also then it could be the bearing in the Alternator, A/C or Power Steering.
There should be a belt routing diagram in the engine compartment that should tell you what the pulleys are.
