So, I'm running 10.4 on my iBook G4 (power Pc) and just downloaded the new updates for quicktime, safari, itunes, the security, and the general update for the Power PC line of macs. After I restarted my computer, I opened up safari again, but then it crashed. After 3 restarts I keep getting brought to a blue screen, and nothing seems to be running. Once its gotten to the log in, but subsequently crashed. I have a paper due tomorrow, is there any way to fix this by myself...fast? Any help would be greatly appreciated...thanks!!
