Need help ASAP - Flasing ?/Finder icon

This is the 2nd time this is happened to me. OS X 10.3.7 - Now when pushing the power button I get the flashing ? mark/finder icon. I've:
• Reset PRAM
• Tried unplugging it and leaving it unplugged over night (worked last time).

There is still the OS X Install CD in it from the last time I repaired permissions (monthly maintence) (ran fine for 2 days after repairing permissions and then this).

I think the CD in there may have something to do with it. How do I get it to eject the CD before it gets to the flashing ? mark/finder icon?
Ok.. I left it unplugged for 2 days and now it booted right up.. :p
