It crucial that the pulleys are all lined up correctly. GM even has a tool with a laser pointer on it to determine the correct alignment. Can you determine where the noise is coming from? I normally use a stethoscope, or a long screwdriver to locate the source of the noise, but this approach is very dangerous, so if your not experienced with this method I wouldn't try it.

if alignment and tension is found ok, check the a/c pressures. too high an a/c pressure will make it harder to turn the compressor and may be caused by overcharged when replaced, too much oil or lack of condensor cooling which may have caused the original one to fail.

compressor is suffering from "slagging". this happens because the compressor is poistioned low and struggles for oil. if your model has the new system to correct this problem then most likely your compressor is going out and will need to be replaced. this is much cheaper than trying to fix the slagging problem.
