Disconnect the flatcable from the cdrom and power up the system (go to the bios setup or set it to pause or something , do NOT boot up the operating system)
Now check if your cd-rom player is still doing the same thing. If it is , it's defenitely a hardware problem and not an operating system problem.
If the problem "suddenly dissapears now" then power off , reconnect the flat cable and boot your operating system in the lowest possible configuration (windows safe mode for instance).
now check again if there's a problem with the eject tingy.
if there still isn't , its a bad driver or something and you could trace back steps on installing drivers/programs/updates/whatever.
