computer turning itself off randomly

[blueberrybubblegum013]

my computer keeps turning itself off randomly, no input to anything but the fan will suddenly crank to max speed, is it overheating? the room it's in is nine degrees with the ceiling fan on. is plugged into a power protector too if that helps. only got the computer 3 weeks ago
