XPS 720 H2C beeps and won't boot up

This question is not answered

Last Sunday my XPS 720 H2C was working in the morning. It sat powered up for several hours. When I went to use it later on, the monitor was blank and the fan was running very loud. I turned it off and left it until Monday. Now when I press the power button the fans power up , the power button stays green, the 1 flashes on and then off while the 3 and 4 stay on, then the 1 flashes on and off again. While this is going on a series of low beeps are heard. One beep, a pause, 3 beeps, a pause and then 2 beeps. The 3 and 4 stay on. And that's it, the fans stay running and nothing else. Naturally my warranty has just expired.
