Do the power supply fans spin?

the Abit NF7 with  MB LEDs has two power LEDs - the red one, when lit,
indicates standby by power.  The green one, when lit, indicates the
machine is powered up.

You seem be stuck in standby mode.  Try the front panel power switch a
few times. (Count to 10 between each try, see if green MB LED turns on)

If that doesn't work, try "aggressively" using the front panel switch.
Sometimes the front panel switch start to fail and they have a hard time 
turning on the signal that tells the system to power up.

These types of power switches are called "soft switches".  used to use
them at Apollo in the early 1980's.  When they went bad, there was no
way to turn a machine off. (or on).

Have you tried clearing the CMOS?
