LG gh22 LS30 problem

Hi everyone. im at the end of my tether. i purchased a brand new LG gh22 LS30 super multi dvd rewriter 22x.
problem is everytime i try to open a disc my computer freezes.
even without a disc in i go to my computer, right click on the drive to see properties and the same thing happens.
everything is connected correctly.
cant seem to figure it out. any ideas?
