I would say the AC is the cause. With the belt off and the AC turned off, you should be able to turn the pulley by hand. If that works, you will need to have someone watch the AC when it is turned on to see if it is engaging and turning, after putting a belt on of course.
If you can see all of the other pullies turning, I would put my money on the AC compressor locking up.
