Two things:
1) Did you follow my suggestion, and unplug the computer before following
the procedure in the manual ? Removing all the cables inside the computer
is not essential, but making sure there is no +5VSB is a good safety
precaution. And for that, I tell people to unplug, so there is no
ambiguity in the instructions.
2) Did you put the CMOS jumper back onto pins 2-3. That is the "normal"
position for the jumper. On some boards, the jumper is needed so the
CMOS well can get power, so it has to go back in the "normal" position.
If the jumper was placed on pins 1-2, while power was applied, on some
boards that burns a small dual diode. On several of my motherboards here,
the device is marked with "K45" in microscopic letters. (I need one
of my small magnifying glasses to see it.) The device has three legs, and
is typically located near the CMOS battery. (It doesn't have to be physically
close, and if the motherboard designer has a weird sense of humor, it could
be almost anywhere. But normally it would be in the neighbourhood of the
battery.
It would be a BAS40W-05 dual diode with common cathode. What happens is,
on some motherboards, clearing the CMOS while the power is running, causes
significant current flow through one side of that device, and it is enough
to fry it. Usually, people who suffer from this, cannot read the letters
on top of the device, because of the physical damage (frying).

If the thing is fried, one guy I helped out, replaced it with a couple
ordinary diodes, and claimed all was well when he was finished. So it
can be repaired.
I hope your problem is you just left that jumper off entirely.
