Why does me cursor/pc/Keyboard keep freezing for about 1 second every few minutes and tries to read something of by CD drive even thougn there is nothing in there (and the little light does NOT even come on to say its trying to read). You can hear it spin, just after the PC unfreezes.
I have tried leaving the door open, then when it gets to that moment it shuts it & also tried playing a disk, which it will start get a few seconds into a sone, stop and tell me there is no CD in there ?

Come on Backoff LOL - whats the crack ?
