ibook g4 problems


My ibook started running very slowly until Sunday where it would freeze when using finder or similiar functions like opening a file. I decided to run disk utility (from the osx disk) and also run 'fsck -fy' both of these found errors, both of which it said they could not repair. I proceeded to run each multiple times each time they would both find more and more errors. My computer seems to be getting worse! Before it would boot up and I could use safari and such, not it doesnt get past the gray apple screen! HELP!!!!!

** Running disk utility resulted in
"Error: The underlying task reported failure on exit (-9972)"
