I was using my computer today and it all of a sudden shut down. I went to turn it on again and it didn't turn on. The power indicater on the power supply also turned off. I unplugged the computer and then plugged it in again. The power supply light went back on but when I hit the power button, the light turned off again. It's smells like a hairdryer and I've had the computer for about six years. Only the last two years o have been using it daily.
