Are you sure, that it's a software problem?
You could verify this by pressing the eject button while the system is booting up. Or boot up a from a Live-Linux (from USB stick) and test it.
If it doesn't work either, your eject button may be broken.

If it's really a windows problem, try booting in fail-safe mode and see if it works then.
If the button works then, the problem is an application that runs in normal mode but not in fail-safe mode. Try to run with as few applications as possible running at once in normal mode.

Maybe some CD/DVD writing applications are blocking the device. You could try to disable/uninstall those, too.

THere's a setting in BIOS. I changed mine from Multimedia first to Function first. Worked fine after that. Also installed QuickSet though and ensured AHCI was set which it was already.
