Hi,

When I turn on the computer, everything boots fine. The problem is when I shut it off. If I go into windows and select Start > Shutdown, the computer will successfully shutdown, but it will not boot again if I press the power button to turn it back on.When I press the power button to power it back up, the computer will power on, the fans will start to spin, the hdd led light will light up, the optical drive will start spinning, but after about three seconds, the system will power off and shut down. It remains off for about two seconds, and then automatically powers itself back on, but appears to be... sleeping?

Please help.

I didn't find the right solution from the Internet.
