While it is nearly impossible to understand that paragraph of nonsense, I am going out on a limb and say that you have the Hard Drive LED plugged onto the header wrong. One way is correct, if it is reversed 180 degrees, the light will stay on all the time.
What color is the LED shining ? If it is red, it may indicate a potential problem. If it is not red, it may not be the hdd LED. My M/B has a LED that shines continuously when my computer power is connected to a wall socket. This is to indicate that power is applied to the board, though the computer may be off.
thx but its not it
i run this pc for more than a year now
the led plug in good
powerled is green
and hdd led is red
wen i go to the bios it turn of
