Drive drawer opens suddenly at startup Leopard Mac OS 10.5

Question

Hi- running into an odd problem, for a few weeks now- At each startup, even before the login window appears, the drive drawer opens - I'm unable to close it again until after login has complete - therefore, unable to restart from a cd/dvd, for example.
Who could help me ?
Thank you in advance .

Not really sure what may help, you could try a few things
...and hope one of them works.
• Resetting your Mac's PRAM and NVRAM:

• Resetting the 'power management chip' in your Mac:

If there is no hardware problem, only a minor logic one, you
may be able to reset something or another to resolve this.
You may also boot the computer into the original software
disc containing the Apple Hardware Test (AHT) and have
it run several duration tests to see if something appears.
You may be able to use the optical drive of another Mac
to test this one. Not sure about the exact process, though.
Perhaps via FireWire Target Disk mode, or some other?
Do you have a second, known-good, keyboard? You could
try different items including another mouse, to see if there is
a related problem with a bad wire or key/button on the USB.
PS: There may be a way, in single-use boot mode, to access
the computer and make it start up from the optical drive. I don't
know how to do that, though.
Have you looked into the System Profiler> software> logs, for
any log entries that may point to an issue on startup? Maybe
in the Console log files (there are several) there is something.
Good luck & happy computing!
