Hello ,
the only thing that i can think of is that the cd-rom is failing and certain parts of it just wont work any more
stop & think it came frome a college and those cd-roms get beat up pretty bad
how old is the computer ?
what department did it come from
the good thing is cd-roms are cheap a dvd player or even a dvd burner will only cost you about $30 to $50 depending on the manufacturer
here is a link to see the prices

other then doing a remote connect to remove the filters
hope this helps
