so, here's my story. So i was watching Lost Highway on my macbook today, and all of a sudden, the whole system froze. the mouse didn't work, pressing the power button didn't work, nothing worked, so i had to pop out the battery and put it back in. whenever i tried to start it back up, it gave me the signature apple gong sound, but right there at the gray screen, it freezes, and repeats the apple startup sound. no matter what i do, it just freezes at that point, and repeats that sound. just for info, i have a 2.0 ghz white macbook. i have the 2 gigabyte ram upgrade. i thought there might have been something wrong with the ram, so i switched back to the default ram, but it still gives me the same thing. i don't have the three year extended warranty, so i can't use the apple customer service phone line. I just wanted to see what you people think, and save me a long trip. thanks!
