asus f2 a85 m mobo sys boot failuer

Solution
Try this: Unplug the power cord and press the power button for 30 seconds or so.
Leave only CPU and CPU fan installed, both 24 and 8 pin power cables connected and start the board. See if the CPU fan is spinning.

@alexoiu , thnx for your reply.
first i tried changing the jumper positions , nothing .
then i removed the cmos battery and changed the jumper positions again , still nothing happened.
and as for your 2nd question , when i power on the pc nothing happenes - the hdd doesnt spin up , the fans dont power up ect. only some LEDs in the mobo light up.
