Hi, I'm hoping someone could help me with this problem I have with my ibook g3 500mhz (640 MB RAM). It seems that this laptop freezes a lot now. I see it a lot especially after I press F9 to show all windows but there are other times when it does this as well. Specifically by freezing I mean that the dock no longer responds and I can't turn off the computer unless I press the off button. The internet continues to respond however. Any ideas and help would be really appreciated!! Thank you!!
