hello. my computer is acting up so weird. i have a mac mini intel and i was in the middle of working with my blogs, then there was an annoying spinning wheel of death, so normally, i would hold the power button for few button to restart and i did. then when the desktop was loading, everything was back to the "new" desktop with alot of stuffs missing, so i restarted it again using the apple menu, then the startup screen took so long and out of nowhere, it shutted down by itself. i tried to power it on again and again, unplugged the cords, still didn't work. now, what's going on, mang? what's the solution to this?
