My computer disk drawer keeps opening at boot up and will not close. If I push it in it closes and then re-opens moments later. Repeatidly. It will not accept a disk. It just keeps re-opening.? Help!

Is there a disk in the drive? If so, try restarting with no disk in drive.

And also try a shutdown and restart as opposed to restarting

Make sure the open and close button is not stuck. If it isn't then your ROM is stuffed. They are cheat at least :)
