Time Bomb Icon at Startup

Hi,

I have a G4 400, white light, with os 9.2.2. Recently having a problem at startup, before the march of icons, it wants to hang up and give me the spinning B&W beach ball in the top left hand corner. It will spin for a min or so, slow down, and turn into a fuse bomb. Sometimes we can reset it and it starts up just fine like nothing is wrong. I have booted off of the CD and run a disk first aid and it has found nothing. It's doing it more and more and not sure what to go after. I get the standard mac startup tone when I first turn on the computer as well.

Any Thoughts, Suggestions?

Thanks!!
