I have a lite-on DVD/CD-RW drive. Usually it works well, but lately (for a few months actually), its been giving me a lot of problems. Every so often, when I put a CD or DVD into the drive, I hear the drive rev up, loading the cd, and then nothing happens. I can't click anything or interact with my computer in any way. If I click the mouse a few times, I hear a loud beep noise and everything is completely frozen, forcing me to turn off the power and then turn it back on. This is especially frustrating when I am installing something on multiple CDs, because if it freezes, I have to start all over again. I have checked the cables, but they seem to be fine. I tried reformatting as well, but that did not help. I don't know what else could be causing the problem.
