err.... after. does the cd drive spins up when u put in the disc? does it try to access? or just nothing?
do u happen to have Nero installed in your system? do u have a Nero program that controls the speed of your drive running? i find that this software somehow doesn't allow refreshing of the cd drive therefore not showing any change when inserting a new disc in.
is there anything else running on the taskbar?
sorry, i can't help more.
