The bow needs to be taken apart to check everything. Get it on a press, and check the limbs VERY carefully. Run a cotton ball over all surfaces in both directions to catch the edge of any small splinters, this will make them more obvious. Check the string/cables VERY carefully and it may make sense to take them off and measure them. Pull the axles and roll them on a true flat surface to make sure they are straight. Last of all check the cams thoroughly to make sure they aren't warped, and that the bushings/bearings are true and smooth.
I dry fired and old PSE edge one time and had to send it back to PSE, I cracked a limb broke cables damaged the wheels and all other kinds of stuff. They just replaced everything but the riser, it was like a new bow when i got it back. Apparently there was alot of damage to it.
