I own a PowerPC G4 running in Mac OS X 10.4.11 Tiger. Ive had it for a long time and never had a problem with it until now. Suddenly the keyboard started taking over typing uncontrollably for example (+++++++++++555+-+-+-) and it also lowers my value until ultimately it freezes. I have tried using the utility repair disc and that usually stops the problem for a few hours sometimes less. When I repair it it mentions something about Invalid Leaf Record count (it should be 3 instead of 20)... I hope somebody can help me out I really would appreciate it... Thank you
