not sure if this goes here-pulley/belt/pump problem
 

well once i start up my car and am about to turn out from somewhere and i turn the wheel, my power steering belt squeaks. now i had someone turn the wheel once and i watched. like the pulley on the pump stopped and belt just kept spinning around the pulley resulting in that annoying squealing sound.

is there anyway to stop this and is it bad (aside from poss. ruining the belt)?

Yeah, adjust the belt! Or, if it is adjusted out all the way you need a shorter belt.

but thats the reason why the pulley is stopping on the pump like it is? like once im driving and cut the wheel all the way it doesnt do it

Does it look like the belt is slipping? How is the tension?
