Hi ,

can anyone please assist with the following:
when i power on my asrock x79 Extreme4 motherboard, the fan turns on and off continuously and wouldn't boot up, so i suspected that the bios is corrupt. I have tried programming the motherboard using CH431A programming tool, using the bios file version L3.21 (located on the ASROCK website). However, it is still not working. Does anyone have any suggestions, steps or methods on how they got theirs to work with the programming of this motherboard?

Thanks in advance.

Why pointing corrupted bios... u messed with it? Does the debug code panel lights up and display any codes.
A broken VRM circuit also does this. This motherboard is fairly esay to flash with SPI programmer, as the SPI is socked, u may try programming with other software versions and compare dumps/original.

Hi guys, thanks for replying back to me, it has helped me think more about the issue. I've been busy this past week so I didn't have a chance to reply.
So I have a bit more information about what happened. When I was playing games one day, the PC freezed and the screen went blue (aka blue screen of death). So I restarted the PC and it didn't work. On the blue screen, it displayed either the code D7 or67. I tried to reset the jumper. I took out the bios battery and left it aside for 5 minutes. Then I put everything back together. I tried to turn on PC again and it didn't work. The only thing that turned on and off was the fan and the code wasn't displayed anymore. This is why I think the bios is corrupted.
Thanks for letting me know it might be the broken WRM circuit since it seems to produce similar symptoms to a broken bios.
I just had another question, is the ASUS bios programing process similar to the AsRock bios programing process? If the processes are different, do you have any tips or guidance on what I can do? I just want to make sure that the bios is not corrupted, which in turn will let me know that the WRM circuit is broken.
Thanks again.

This explanation u should told us before...D6/D7 (Input/Output device error) is in fact DXE driver initialization during AMI HW bios post, but not related with BSOD on a live OS.
BSOD when gaming... can be caused by GPU fail, RAM fail, disk access fail.
Before any SPI attempts , have u tried other GPU, only u RAM stick, drives disconnected?
Does the motherboard still display the same debug codes? Does it power on 1 to 2 secs and shutdowns/cycle?
SPI programming is similar to Asus and others, SPI socked or soldered mainly the diference. Try to read/backup its content.
