I've just built my first computer, and it all works very well. However, I have noticed that when i switch it on at the mains the computer emits about 3 or 4 beeps of varying length without me touching it, and then the green power light stays on even though the computer is off. The motherboard I am using is an ASUS P4P800-X. Is there a way to make it turn off properly or stop the light showing when it's off, or has anyone else come accross a similar problem before?
Thanks in advance.
