cd-rom not working

[FungMenChao]

hi, i have a problem with my cd-rom player
when i put a cd into it , it doesn't load and there is no light
i tried cleaning it but it didn't work
then i took apart the comp and the drive was still spinning
but only for a while (it stops spinning after u put the  cd in for a few secs, then stops)
please tell me what is wrong with my drive
Thanks
