Ok, since a week ago the entire computer gets very very slow, with a lot of lag. I place the cursor over the dock and it takes minutes to show up. There is not back ground processing. I just updated the OS and took away the extra ram I had (a rev "B" Powerbook). Is like if the hard drive were very slow but is not that. I tryed to restar the computer and even for that is slow. I checked the hard drive and fix some problems but nothing. I just do not want to back up EVERYTHING and re install the system because I have so many software running! with updates and stuff. It would take me at list a week. Any way, any sugestion?
