Hi All,
Recently I updated my home built PC to Windows 8.1, there was an issue with my HD audio not working so I thought a BIOS update would help, which it did but Windows 8.1 had SecureBoot watermark, which I tried to fix by configuring manually configuring my SecureBoot BIOS features. This cause my computer not to POST, I there reset my machine by removing the BIOS battery and jumping the Clear CMOS pins, this got me back up and running with a BIOS restore. I then configure my SecureBoot properly and had no more watermark, the system seemed to work fine restarting multiple times with no issue until I shutdown. On the next cold boot my machine would not POST again. I repeated the steps above multiple times, but I cannot get the PC to POST at all now, the odd time if I do a reset while it's booting, it will POST and try and go into the BIOS setting and then shutdown. I have no idea what is wrong, is my motherboard toast, is there anything I can do to fix it? help please.

Your video card could be the problem. It isn't a UEFI video card and some people have fix it.
That is with updating the bios on their card to support UEFI. You need a GTX-660 or high to do this.
You might have to force the backup bios to kick in. http://forum.giga-byte.co.uk/index.php/topic,13351.0.html

I'll give it a try, but where can I find an older BIOS update, I try to find them on the net with no luck.
Does Gigabyte have an site for downloading old BIOS flashes?

You can look at these ones.

Thanks, I'll try this....you mentioned I should use update F14, is there anyway to know what was fixed with each BIOS releases on this page?

:) Thank you so much, I'm up and running without SecureBoot enabled, I guess I leave it off for now, with the dumb watermark.
I tried to update my Video Card Bios using VGA Tools - @BIOS but the tool says it can not detect my video card, is there something I am missing?

You have a older video card and even if you could update it. It still might not support UEFI. You might have to do some research on that.
