Recently, when I turn on my computer, its various fans and lights shall turn on, but is does not make a "beep" to indicate that is successfully passed its power-on self test (POST), and nothing happens. I can solve this problem by turning off the switch on the power supply, waiting for several seconds, and then turning it on, again, after which my computer shall start up perfectly well, but I am worried that this may be eventually become a greater problem, and that my computer may never start up, again. What does everyone else say about this?

In the case that it is relevant, my computer has an Asus Crosshair V Formula-Z motherboard.
