i seem to be asking questions in all the sections anyways, my fiancé has a macbook that sometimes just decides to stop functioning. you might have just woken it up from sleep, you may have been using it doing something ordinary like surfing the web. it seems like it happens at random times. what happens is, that basically the screen just freezes in place. cursor doesen´t move, no animations or movements, everything just stops entirely. if there´s any audio playing, it does a glitchy loop. the caps lock and num lock buttons won´t glow green when you click them either, so something is definitely not right (obviously). the only option at that point is to hold the power button and do a hard reboot. anyone know what could be causing this? anything i could check at all?
