hi, i have a asrock 775i65G Rev 2.0 that starts but does not display any image.
I put a debug card on pci slot and the following hex code appears 13 20.
Steps that i have tried:
Reflash bios , i went to the support site of the board and download the dos version to do the reflash, but this does not solve the problem,
I put external video card on slot agp but the error code is the same so this does not resolve the problem,
I not sure but i think i have a small short in the 3.3v line because when with analog meter in scale of x1 black probe in gnd and red probe in one of the 3.3 atx line i have 600 ohm resistance but when i plug the vga cable one the vga port of the board there is no resistance mean a short i think,
I have a variable power supply that i use in the line of the 3.3v the only component that gets warm is the south bridge, is this meaning the component have the short?If so why the board still can turn on and display bios codes in the debug card stopping on the 13 20,
Can some one help me debug this, i whant to understand if the problem is in this component or not.
The debug card can tell me if the reset sinal is ok and i think that is ok because on the turn on the led lights one millisecond and then stays off meaning that IC super io resets south bridge and south bridge resets north bridge for the board to turn on all the devices.
Sorry for the long history, but i need some guidance,
thanks.
Regards, Diogo.
