If you don't see any such jumper it usually works to pull the power cord out and remove the quarter-size battery in the middle of the board and let stand for awhile, say while having lunch. I usually time it so there's a long time span while I do something else.
Thanks for the information. The jumper is labelled JBAT1. It's next to SATA ports 3 and 4 (on the right side of the board, near the back, as seen from the rear of the PC).
The procedure I suggest is:
Power down the PC.
Turn off (or unplug) the PSU from the mains.
Hold down the PC power switch for a few seconds, to discharge any remaining charge in the PSU.
Install the jumper in the clear position. Leave it for about 10 seconds.
Disconnect the jumper.
Power up.
(Pray.)
Sounds like a faulty rail in your power supply unit.Either substitute a known working PSU or have yours tested.The test only takes 1 or 2 minutes.

I would look around. Newegg had it on their site when I pulled up your motherboard. The units with the cables that you plug into the supply may cost more. At least if the shipping is that cheap, you may want to get a good power supply that also protects your motherboard, since it is a better quality one.
