Hardware Problems

Hi, Its me again. I have a compact computer 5000 series and it cam with a cd rom and a philips 4801. On saturday I bought a liteon 24x10x40x. I took out the cd rom and put the liteon as master and the philips as slave. Now the liteon won't stay closed. I push the button to close it, it looks for a disc, and then it opens. If I put a disc in it will close look for a disk and then open. It seems to be malfunctioning. Is it because I have it as master? Or is it because I took out the CD ROM? Thanks for your help.
