powerbook G4 17, 1.67 cannot start up after stuck in uninstallation of Safari4

[geneseandannzh]

My powerbook G4 cannot start up after I forced to shut down the computer that was stuck in the process of uninstalling Safari4. It worked perfectly in the past 4 years with 10.4 and 10.5. Because Safari4 cannot work with Hotmail, I wanted to delete it using the unstallating package. It stuck for long time so I forced it to down. I rebooted the computer but it is always at the grey screen with Apple in the center and a spinning wheel.

How can I try to get it start before I have to bring it to an Apple tech for 4oo boxes.

Thanks a lot.
