I turned secure boot on my w10 PC to play the stupid BF6 beta and now my monitors are constant signal loss. Can't see my bios to even access it. I was having D9 error for boot error then I took my GPU out and that went away but now my monitor connected to the MB still gets no signal.

nvm the D9 (boot error code) is back without the GPU in now too.
I did a cmos battery reset and cmos jumper with a screw driver and still won't boot to bios.

Did you have the pc unplugged and the psu capacitors drained when you did this
What are your full specs
alpine cedar
Did you have the pc unplugged and the psu capacitors drained when you did this
...
Uh i unplugged the pc turned the psu off and held the power button a few times and I let the cmos batrery sit out for about 30 minutes while I did everything. Also I have a z390 aorus ultra MB, 2070 3 fans, i9-9900k, 48gb ram, nzxt cpu cooler, then a benq XL2411k monitor, then a evga psu believe 750 bronze?
Everything was working fine till I changed the bios to secure boot instead of CMS
neat pumice
48GB ram?
alpine cedar
48GB ram?
I have 32 gb from corsair I recently got and 16gb tforce Vulcan thats few years old when first built cuz I needed more for Minecraft I think lol 😅

I’d try taking out one of those kits just in case there’s something weird going on with it

just tried it, still no signal given to the monitor and d9 error

Hmmm
Did you for sure short the right pins for the cmos?
I see your motherboard has a TPM header but not necessarily a module

Yeah the ones at the bottom near the plugs for the system fans
Held the screwdriver between them for about 20 seconds? And i had the battery out
neat pumice
Yeah that should have done it
alpine cedar
Yeah idk if it's not resetting the bios or what but really wish itd just post to the monitors so I could just turn it back off lol
I even tried unplugging each ssd individually to see if itd help
Cuz i have two mx500 crucials 1tb
neat pumice
Yeah this is so weird

What exactly did you enable under bios?
Because enabling secure boot would have nothing to do with display
With it being a gigabyte board you can try and q flash the bios.
Try plugging the monitors into the igpu too
@alpine cedar
alpine cedar
What exactly did you enable under bios?
I disabled the CMS support thing to enable secure boot then it asked me to do something with the PK keys and so I restored that I believe it had me do so I could then enable secure boot then both monitors went no signal everytime I boot up
vestal socket
With secure booton gigabyte boards, you need to disable csm. Save and exit. Restart back into bios. Enable secure boot. Save and restart back into bios. Make sure its still enabled. Then start the pc.
alpine cedar
Thats what I did then it basically never gave signal to my monitors so I cant enter bios cuz I cant see what im doing when it starts lol
vestal socket
You dont want to enable PKI keys
alpine cedar
well it said I couldn't enable secure boot without it 😅
vestal socket
Interesting
alpine cedar
The bios itself said it
vestal socket
PKI should give you a public and private option.
Regardless, try q flash with bios
Or try the igpu first
alpine cedar
the mb doesnt have a slot for my benq or ultrawide 😅
Might have to buy an hdmi cable
Its only got an hdmi slot
vestal socket
Also intel trust support enabled for secure boot. PTT
alpine cedar
Don't i need it to post to a monitor tho to qflash
vestal socket
The motherboard has to have an igpu slot
alpine cedar
I dont see a DVI slot for my two monitors, just an hdmi
vestal socket
Go grab an hdmi cable from a TV ya dingus
DVI ... da fuck
Display port or hdmi should be it
alpine cedar
Either dvi or dp 1.4 i forget but either way not a slot for the cables 😅 have to go buy an hdmi cable to try hdmi
vestal socket
Use an hdmi cable from a TV in your house
alpine cedar
I dont have a TV i just watch things on my ultrawide which is mounted lol
vestal socket
You have absolutely no hdmi cables in your place. Or know someone with a TV or spare cable?
alpine cedar
Nope
vestal socket
Da fuq
alpine cedar
I might have one from my old dead monitor i can see but I remember it not working for my benq when I plugged it in
A long time ago
vestal socket
Never hurts to try. Remove the graphics card when you do to be certain. You have a very old system. Its possible something just ... died
I know people who have had this issue when enabling secure boot on old system. I can almost gurantee you just need to use the igpu on the motherboard to get back into bios and reset it.
You need to make sure the gpu is removed to be sure. If it still shows black screen after you can do q flash with bios and igpu hooked up and it will work.
You need to make sure csm is off, secure boot is enabled, and PTT (intel platform trust technology) is enabled as well for old intel systems

Yeah it didnt work but could just be a bad cable not sure
vestal socket
You removed the gpu?
alpine cedar
You removed the gpu?
Yeah
vestal socket
Yeah
Then get another hdmi cable. If that doesn't work then q flash the bios. Your mobo supports it.
So long as you took out the cmos battery, left it out for a while, and it didn't reset bios. You jumped the pins properly and that didn't work. Then thats your last option. At least in my experience with this issue.
vestal socket
Yeah
Wait, your mobo has dual bios. A physical switch. Just flip it, and it should work.
vestal socket
Rip, I thought i had something there
According to the gigabyte website, it still has dual bios and a mechanical switch
@alpine cedar
This is from their support site
.
.
.
Method 1
Shut off your computer
Hold the power button until your computer starts and shuts down again
Press the power button again, your backup BIOS should kick in now and should re-flash the backup BIOS if there's anything wrong with the new one.
Method 2
Shut off your computer
Hold the power AND the reset button for about 10 sec, than release.
It should boot into the backup BIOS now.
Method 3
I’m not recommending this solution. Didn’t tested it by my self.
Only use this if nothing else works.
Short out pins 1 and 6 on the main BIOS chip by attaching a jumper to both the pins (pin #1 should be marked with a red dot or whatever)
Tell a friend to press the power on button while you do this because right now you are holding the jumper on the pins
Remove the jumper you're holding between pins 1 and 6 as soon as you hear a beep.
Backup BIOS should boot now.
alpine cedar
Idk were the only thing I see is these 2 things marked bios no switch just 2 chips
vestal socket
This was from their support for your mobo, duno. But see if any of those methods above work.
@alpine cedar
alpine cedar
Well both are marked green if those are the alleged switches...
alpine cedar
Well the first two didnt work and both are marked green 😅 so idk which one to do
Oh wait are the pins opposite buttons cuz ones closer to first pin of one chip then 6th pin is marked closer on the other chip
vestal socket
And from the computer being shut off. You held the power button down, until it booted it and turned off?
Never lift your finger off until it boots up and shuts down again
alpine cedar
Yeye I did
I even tried another time, holding it till it booted back up again after the shutdown
vestal socket
Doing it again after the shutdown boots back into original bios. All you need to do once it powers off, is turn it back on.
vestal socket
It has dual bios.
calm coral
It has dual bios.
what seems to be the problem?
vestal socket
He can't get it to reset at all, apparently done everything from jumping pins to forced restarts and removing the cmos
calm coral
uh
vestal socket
He has the issue where turning on secure boot borks the bios
calm coral
did he ever update bios ever since he bought the pc?
vestal socket
Im guessing not. I tried telling him to use q flash, as its a gigabyte board
calm coral
Im guessing not. I tried telling him to use q flash, as its a gigabyte board
turning on secure boot without latest bios update might fuck up bios
vestal socket
I guess the pc works, but no signal for the monitor. Its a known issue with turning on secure boot on old boards
vestal socket
I said to use the igpu too, tried that route. But bud doesn't have a single hdmi cable in the house to test it
calm coral
then do it its a godo thing
i fucked up a laptop with same issue
and there were no options for flashing
no display
no flashing options
vestal socket
I've had success with this issue with using the igpu and it works fine. But he doesn't have a single hdmi cable to use for it.
vestal socket
Yeah. I think its a mix of user error and not knowing at this point. Because he kept saying he had a dvi cable
calm coral
so you had output to the monitor
vestal socket
He did at some point
calm coral
Yeah. I think its a mix of user error and not knowing at this point. Because he ...
never gonna do shit to any old pc's without updating bios first
vestal socket
But thats basically it in a nutshell
calm coral
ngl
vestal socket
Same
Its just funny how many people are having issues just enabling secure boot lol
vestal socket
I didn't have mine enabled either, I was sure I had it on at some point, but oh well. New board so I probably forgot after one of the resets. I had some issue with my 9800x3d
calm coral
laptop was refurbished
it should have latest enough bios to let me enable secure boot 🤔
vestal socket
"Should"
calm coral
i dont think the refurbished cared enough to update bios
vestal socket
Basically pcs in a nutshell
calm coral
since i've worked in a refurbishing company for 9 months
but they always did
but yeah
there were many things they didnt
vestal socket
Yeah, the joys of refurbished things.
calm coral
Yeah, the joys of refurbished things.
never trusting refurbished things ngl
alpine cedar
Am getting a flash drive to qflash it rn
vestal socket
Q flash should work, if it doesn't, you are left with the igpu. At that point, I dont know.
alpine cedar
Yeah. I think its a mix of user error and not knowing at this point. Because he ...
Its a display port i corrected after saying dvi
calm coral
what is igpu gon do?
alpine cedar
cuz i have benq monitor and the main chord they give you is display port 1.4 cable which the MB doesnt have slot for xd
calm coral
dp 1.4
vestal socket
1-3 Using Q-Flash Plus
A. Before You Begin
- From GIGABYTE's website, download the latest compressed BIOS update file that matches your motherboard
model. - Uncompress the downloaded BIOS file, save it to your USB flash drive, and rename it to GIGABYTE.bin.
Note: The USB flash drive must use the FAT32/16 file system and it must be a USB 2.0 flash drive. - Insert the USB flash drive into the white USB port on the back panel.
B. Using Q-Flash Plus
If both the main and backup BIOS fail during system boot, wait for 15-20 seconds, the system will automatically
search and match the BIOS file in the USB flash drive on the white USB port. The FBIOS_LED will flash when
the BIOS matching and flashing activities start.
Wait for 2-3 minutes and the FBIOS_LED will stop flashing when the main BIOS flashing is complete.
After the main BIOS is flashed, the system will reboot automatically and then DualBIOS™ will
continue to update the backup BIOS. After completion, the system will reboot again and boot from the main BIOS for normal operation.
From your mobos manual
vestal socket
what is igpu gon do?
Using the igpu bypasses the setting in bios to display using a dedicated gpu. So they "should" get signal.
Had a similar issue on an old 6700k
calm coral
Using the igpu bypasses the setting in bios to display using a dedicated gpu. So...
hmmm
not a big deal unless the ports on your mb and gpu arent same
vestal socket
I mean, technically they are, both use hdmi, just he used the dp cable for the monitorm
vestal socket
Yes, but he doesn't have a single hdmi cable or TV in the house to borrow from
Or a friend that has a TV, or cable:(
calm coral
Yes, but he doesn't have a single hdmi cable or TV in the house to borrow from
understandable
alpine cedar
I just use my phone and my mounted ultrawide I never needed a TV 😭
calm coral
no problem
vestal socket
Shit if I lived in an apartment, id knock on my neighbors door and be like ... "odd question, can I borrow an hdmi cable" lol
calm coral
i mean why not
vestal socket
Unless you live in the ghetto yeah, why not lol
calm coral
should have good enough relation with your neighbours so you can borrow small things for some time
someone people live in same apartment for months and be like "yeah idk that person"

You need to enable 3 things.
You need to make sure csm is off, secure boot is enabled, and PTT (intel platform trust technology) is enabled as well for old intel systems
Also, because you updated bios, it reset everything. Make sure to reenable xmp for the ram as well.
So the enabled secure boot was reset to being off
alpine cedar
Do you know what place to go for the ptt setting?
Oh I found it
Its already enabled
And it broke again gg time to go get the hdmi chord again
Guess im not playing battlefield
It boots through secure mode with my IGPU but not my GPU @vestal socket tho my Nvidia drivers are up to date
Like im in bios rn through my igpu and it's fine

@alpine cedar
Woops, misclick
Was going to ask if you got it fixed, didn't see how long the chat was and discord lagged when scrolling down
alpine cedar
Yeah i got my pc fixed but I dont got the secured boot working
It just bricked my pc again
Had to go through entire process again
half chasm
@alpine cedar This is a pretty old bug which should be fixed on newer boards. Basically, Secure Boot has a chance of locking out the GPU. I've had users have to try three times
Just unplug the GPU, disable secure boot, plug the GPU back in and try again
You can also update the BIOS first if it's an old version in case it has been fixed
half chasm
Gigabyte board?
alpine cedar
Yeah
alpine cedar
Z390 aorus ultra
half chasm
I don't have any tips other than just repeating the process and trying again
alpine cedar
Well i just did it the 2nd time 😭 nothing changed
