My cd rom drive isnt reading any discs? - emachines cd drive wont open

I have a desktop computer, eMachines T Series 3624th I try to install the Netgear router CD is not my computer and read it when I put my CD in. The same applies for each CD to dispel. The opening and closing, but I usually read, go to my computer and it does not show any removable media or CD at all. What should I do?
