yesterday, i turned off my powerbook (g4 12", i think 1.33ghz) because it was running really slowly. i left it off and then i tried to turn it back on but it still ran slowly so i tried to force quit shit and shut it down, but it froze up so i shut it down by using the power button. after doing this once or twice more, eventually, it would get stuck at the opening screen (grey background, apple logo, spinning circle) for 5-10 minutes and eventually move to the next screen (blue with spinning circle) for a long time and just get stuck there.
