I dunno you can try resetting the BIOS, but since you never did anything in the first place I don't know why you would. As for opening the cd drive, when the computer is shut off, take a paperclip, unravel it so its straight. Your cd drive should have a lil hole near the tray, stick the paperclip in there and it should open. Put the Win XP install disc, and see if anything happens when you boot up. G'luck.
