Did I kill my motherboard?

[TiredEngineer]

My computer has been rock steady for close to a year (Gigabyte Z170X UD5) with a 6700k.

I decided to add an SSD and a HDD yesterday (and do a full format). As part of this I also flashed the BIOS to F20.

Everything was fine. I secure erased my SSDs, and then randomly was poking around in the freshly reset BIOS before reinstalling Windows and for some random reason decided to enable secure boot. This has promptly caused my motherboard to bootloop indefinitely. It gets to code 97 and then cycles off. Code 97 is "Console Output devices connect (ex. Monitor is lighted)."

I even removed the GPU to try using onboard video. I also removed all RAM other than 1 stick. I took the motherboard battery out for roughly 15 minutes and have furiously mashed the clear CMOS switch many, many times.

No matter what...code 97...shutdown. Rinse and repeat. I double checked all my connections, but I didn't really mess with much other than moving some drives around.

Edit: Adding some details of extra steps I have now taken below.

Did you try resetting your CMOS by shorting your pins (page 35 in manual)?

What about your Dual BIOS feature? http://forum.giga-byte.co.uk/index.php?topic=9462.0 or https://www.gigabytenordic.com/gigabyte-tips-tricks-rma/

The F20 BIOS update, from what I have read, has some serious quirks.

Thanks for the reply. I didn't realize what the dual BIOS was. I actually tried to force a dual BIOS recovery using quite a few methods from a quick Google search (and your links) and I still get to code 97 power down with no post. Been building systems for about a decade now and never had a problem this perplexing.

Have you tried removing your SSD and HDD to see if that would allow you to get into your BIOS? If you have, I can't think of another way to fix that issue outside of the first two I recommended.

Apart from the suggestions that have been given already, I have to confess that I came to this thread because the header in the topic list says that the subject of this discussion is "Did I kill my mother" and I had to see if the thread was as silly as my brain imagined it would be.

What happened when you cleared the CMOS with a jumper?

It looks like there is a similar issue to this acknowledged by Microsoft:

I removed the battery for probably over an hour now, I shorted the jumper, and I used the CMOS clear button like it was going out of style.

I tried forcing dual BIOS quite a few different ways.

I removed all drives, all but 1 stick of RAM, and tried different pcie ports for the GPU. I also tried the igpu with no gpu plugged in.

Boot -> code 97 -> shutdown -> boot -> ...

I am thinking of grabbing an Asus z170 AR from Microcenter tomorrow, but would prefer not to spend that money, make the drive, and deal with reinstalling CPU/heatsink.

If I actually got a post I was thinking of flashing to an older BIOS, but then I noticed this on the Gigabyte website:

“ * This BIOS prohibits updating to earlier version BIOS”

In this thread, in the last post, I linked to a Hardforum post about the F20 update:

http://www.portvapes.co.uk/?id=Latest-exam-1Z0-876-Dumps&exid=thread...ds-and-new-app-center-and-siv-issues.2483155/

In it, a person ended up having to send his board back to be reset to an earlier BIOS update.

However, people in this thread found a way to revert back to an older BIOS version, so maybe you can find a way to do it in there:

I was having the same issue as the original poster and went through the same steps to try and resolve it. Someone on Tom's Hardware had this problem (link). I did as as he did, but I shorted the 1 and 6 pins and now I've got a working computer again!
