Cdrom/dvd drive problem,need help: desperate

Okay, so here is the problem, at random times while i’m using my computer, my CDROM / DVD drive busy lights will come on, even when both of the drives are empty, then my computer procedes to freeze :frowning:

This is completely random as far as i’ve noticed, it keeps causing me to lose valuable work, and decreases my effiency by tons…

I’ve noticed when i restart my computer, a black screen comes up and says:
The following configurations have been updated:
C: 388,834mb, drive3: cdrom, drive4:cdrom…

every time, except some times, drive 3, and drive 4 are blank, and when that is the case, my computer doesn’t even detect the cd drive or the dvd drive, and they have no power…

Anyone have any idea what is going???

:puzzle: :m: :frowning:
