freezes right when os loads

[gm628]

The ibook has classic os and 9.1, i accidentally switched it back and I can't get it back because the computer freezes whenever I startup the computer. The desktop loads, then it's fine. But then a pink-reddish outlined box appears with the half-face and a text bubble icon and the box doesn't say anything, it only has an ok button. but, before you can press the ok button, a bunch of icons load on the bottom of the desktop and it freezes.
Please help.

-Thanks

Try holding down the shift key immediately after the chime, this will allow you to boot with extensions off. Then, launch Extensions Manager from the control panels (Apple Menu) and enable the Apple extension set only and reboot again.
