computer is down!

[sublime]

yo-

im on the laptop right now. check this out. i go to jump in the fart sack, and after taking care of some forearm exercises, i am just sitting there thinking about life and stuff. i hear this 'ding' from the desktop (kinda like the one PT makes when its done exporting player notes) i pay little attention to it. then i get up cuz i want to check on something and the computer is off, but then restarts until it gets to the windows screen then shuts off again and immediayly restarts. i tried unplugging it, and then restarting...that didnt work.....what the hell is going on? is my harddrive fried?
