So lately i've been having some trouble with my powerbook.It has been freezing/crashing. I called applecare and they recommended a total reinstall. I told applecare how I had my drive partitioned and they suggested I erase it all and start again. They then suggested that I only install the essentials slowly to try and test is hardware is causing the random crashes I was having or software. So I assume that I should be installing fresh copies of software from the CDs but slowly. Right now in about 20 hours of using it I've had no crashes. I have only basically set up safari and ichat to use. They said I should slowly add applications as I feel comfrotable. I have to add back microsoft office, dreamweaver, and VLC and a few other apps but I'm gonna keep it minimal at what I use the most. How big do you guys think the intervals should be? a day and a half? I'm just trying to figure out the best range for testing purposes. Any advice would be great.
