you should def get SP2

your first problem was pulling the plug... that is the last resort. The best thing to do it hold the power button for 5 seconds and let it power down. Pulling the power on a something like a computer is about the worst thing you can do besides something physical like throwing a magnet or glass of water onto the computer. You best bet is to make a new profile back up all your data and documents and then reinstall windows
