IBook G4 black screen at startup with code in upper left hand corner

Question

I have had operating system issues for the past year, and recently had my OS reinstalled at a Mac Professional retailer. After two weeks of perfect performance, the chime stopped working on startup. This was the only problem for several days. Then when I would put it to sleep, the computer would not automatically turn back on, I had to manually reboot it. Finally, today, after the computer would not wake up and I had restarted it, the screen would flash to the apple logo screen WITHOUT the spinning wheel and after several seconds would shift to an all black screen with text in the upper right hand corner, waiting for a command entry.
The code reads as follows:
hfsswapBTNode: invalid node kind (-9)
node=22016 fileID=4 volume=Macintosh HD device=root_device
-sh-2.05b#
Any ideas?????

Answer 1

Put the install disc in the drive and start while holding the "c" key. Once satrted click through past the language screen and select Disk Utility from the Utilities menu. Highlight the drive on the left and click the Repair button. If it reports errors and repairs repeat the process until no errors are reported. If it reports errors it can't repair post the error message here.
