alright well it just seems to be shutting down at odd times. i just did a pram reset in attempt to remedy it refusing to wake up beause of (i'm assuming) the new cpu and mce drive. i woke it up, squeezed the bezel to fix the flashing screen (cable issues), and then it shut down. i did a restart and it shut down as soon as it reached the desktop. another restart and it shut down even before the screen turned on. right now it seems to be running fine, so there doesn't seem to be any regularity to this. possible a pmu or pram issue cuz of the reset?
