what did i do to my powerbook?

with my work on finding a new browser, i attempted to install ram doubler and speed doubler on my powerbook. they weren't supported versions, so i deleted them. the hotline software that i used might have caused issues since the computer keeps freezing on me. how should i go about fixing it? hard drive erase will be hard since the floppy drive is broken, and i don't have a cable to connect it to my classic and use that floppy.
