i hadn't rebooted in about 2 weeks, so i figured i might as well. i reboot, it takes exceptionally long to reboot. it finally boots and is running fine. except that the fans are blowing at 100%. its not running hot, there aren't any processes eating up the processor... so i reboot again. this time it just sits at the gray apple screen with the circle spinning, forever. the fans blow at 100%, i can hear the hard drive doing some work, but it never moves from this screen i tried resetting the pram. no luck. booted up with my snow leopard disk and ran disk permissions. it barked a ton of errors with flash player, i remember that i recently installed a new flash player a few hours ago. still won't boot so, i go to try and reinstall. i wanted to reinstall with the archive and save user information option selected. i did not see that option anywhere so i clicked next its installing os x again i think i just hosed my system. damn, its been over a month since i backed up anything on my macbook. we'll see what happens after it completes the install moral of the story - back your shit up regularly...don't ever reboot?
