You most likely have something plugged in wrong. Check all your conenctions.

Last week I was working with my ASUS A7V133 when it suddenly came to a
strange state: the front power light was blinking in the same way as if
it were sleeping. But nothing would make it alive, only this 4 sec press
on the power button would turn it off... and never on.

Now, when I turn the rear switch off for enough time (enough for the
mainboard led indicating power to turn off) and back on, if I press the
power button, the front light will be on for 1/10 sec and then off.
Nothing inside will move.

This is pretty annoying for it doesn't seem to be a power supply failure
(the mainboard seems to be powered), but who knows with these ATX boxes?

Can anybody give me a hint?

Thanks in advance,

David.

Open the system and examine the motherboard for swollen/leaky/vented
Capacitors, or residue under them, and of course anything else that
might be out of place, wrong, damaged, etc, while you're in there.

Has anything happend or been changed just prior to the onset of the
problem?

If you haver a voltage meter you might take voltage readings at the
motherboard power connector (while the system is "on") including at
least the +3, +5, and +12V lines. If proper voltage is preset you
might try turning off and unplug the system, unplugging the power
supply from the motherboard, then plug the power supply back into the
main ac, and finally short the power-on line to ground to see if the
power supply stays turned on. Leave only a hard drive connected to
the power supply at this point. So long as the power-on line is
shorted to ground the power supply should stay on, it's fan spinning
and the hard drive also spinning. Here's an aid to the pinout on the
ATX connector for the voltages to check and the power-on line:
