Every now and then, my Sony vaio fx103 is not powering up. I am getting an intermittent problem where the computer does not power on when I press the on button. The lights flash once, the disc apparently spins once and then stops and the lights go off. Pressing on to the power switch continuously causes this to occur repeatedly, but like a car with a live battery but that is repeatedly turning over and not starting, the computer does not power on. After some hours or days, it starts working again as if nothing happened! Has anyone come across this problem?
