Can't clear CMOS Asrock Extreme 3 Z77

[Systematic]

Hi guys, I'm unable to clear the CMOS on my Asrock Extreme 3 z77 board. I went to update the bios, and the computer shut down in the middle of the update, and now it will only turn on but nothing comes onto the screen. I have tried clearing the CMOS by unplugging the power cord, waiting 15 seconds, then moving the CMOS pin jumper from the default 1-2 position to the clear CMOS 2-3 position. I then waited 5 seconds and proceeded to hold down the computers power button for 15 seconds. After all of this, I put the jumper back to the default position, plugged back in the power cord, and powered on the computer to no avail. So that method didn't work, and I tried it several times. I also tried taking out the CMOS battery for a half an hour and putting it back it, but that also did not work. I have replugged in all of the cords to make sure they are plugged in correctly.

Hi, I suggest ordering a BIOS chip on ebay and replacing the board's one (it's on socket and easy to replace).

Hi,

Failed Bios update most likely means the mobo is no good.
Donwload the bios to usb and try to boot:

You will need to replace the BIOS chip on the board since the BIOS is most likely corrupted. I'd look on eBay for one.

not good .. best I remember if you stop the bios flash before its complete its most times bricked ... I don't see any recovery tool and seems you don't have a duel/backup bios .. now you may contact asrock for this from them if all else fails to get it going
