What does the red light on motherboard mean?

I turned the computer on by shorting and i saw a red light on the motherboard , what is that supposed to mean?

Look it up in the manual.

To make it easier, download the PDF version and do a search for "EZ Debug"

read the print on the motherboard, the light is above VGA, which means your having a gpu issue or lack there of.

thanks. I found the issue. It's my graphic card is broken.

@pyro1245: did any motherboard have this function? I can not found this function on my motherboard.

Motherboard status lights can vary more wildly than the PC vs Console argument from board to board.

Depends on the mobo. My has a two digit code, although it can also replace the digits with some letters.
