When TPM is enabled and upgraded to w11, no display appears.
When TPM is enabled and upgraded to w11, no display appears.
Hey there, I keep coming back to these forums to seek advice on possible fixes for my hardware issues.
Details of my setup:
- B550m pro 4 ASRock motherboard
- R5 5600G processor
- Two 16GB 3200MHz DDR4 RAM units (or previously had 3200MHz after some tweaking a few years ago, now it’s down to 2133MHz when checking Task Manager)
- ASUS GTX 1080 Ti graphics card
- Corsair RM 750 power supply unit
What I recall doing:
- Updated the BIOS for a possible W11 upgrade (the update was long ago and didn’t cause problems, but the Windows 11 upgrade happened recently)
- Activated TPM in BIOS with Windows 10; it took some work to get it enabled properly. After saving and rebooting, I noticed the boot display disappeared, though the Windows display remained visible
- Chose to switch to Windows 11 hoping the issue would resolve, but it didn’t. The update worked well after the first day, and even on subsequent launches it functioned normally, except for the third time when display problems appeared
- Tried clearing CMOS using the jumper pins with a screwdriver once; it resolved the boot screen problem but not the loading/update screen issue
- Found that if I fully shut down the PC and removed the PSU cable for about half a minute while pressing the power button briefly, then restarted, the screen would flicker briefly before stabilizing. Holding the DP connector gently on the GPU seemed to stop the flickering quickly. The only DP cable I have is the one included with the monitor, but I suspect the problem isn’t the cable itself
- Previously, clearing CMOS with two jumper pins fixed the boot display issue (though it didn’t solve the loading/update screen problem), and I’ve noticed the display works normally when I completely power down and disconnect the PSU
Currently, I’m dealing with a boot display issue that started after enabling TPM. I’m not sure what’s causing it—last time I moved from Windows 10 to 11, I lost the boot display feature in both versions, except for the loading/update screen. Now I’m experiencing this problem again on Windows 11, and I’m trying to figure out the right solution.
I’ve also tried using just one DP cable as a temporary fix, but it didn’t help with the flickering.
Any ideas would be greatly appreciated!
PS: This is my second ASRock motherboard; the previous one from 2012 had similar problems when I upgraded from Windows 7 to 10—specs said it was compatible, but the boot screen disappeared. It worked fine otherwise except for the loading/update display, which also vanished during the Windows 10→11 switch. The only workaround I found is disconnecting the power source briefly and plugging back in.
I was confident upgrading to Windows 11 would be a good experience, but it didn’t turn out that way this time...
Enabled TPM on bios with W10 required some adjustments to activate it. Once I managed to turn it on, I saved and restarted my PC, but the boot display disappeared while the Windows display remained active. If it was hidden, what steps were taken to enable it? If you upgraded via the internal upgrade method, creating a new Windows 11 USB installer is recommended before a clean installation. For clarity, which BIOS version is your motherboard running?
Maybe the greyed out option isn't the most accurate way to describe what I did. I performed this TPM adjustment about 1-2 months ago, so the information is returning gradually. Here’s the video I used to activate the TPM: https://www.youtube.com/watch?v=03Zjo-RyYbI. After rewatching it, I could have made a mistake during the process. In the video, the secure boot state appears to be off while system information shows it's on. I spent several hours trying to locate this video again...
Regarding the bootable USB installer, I considered using it at that time. Perhaps I chose the installer assistant instead. I believe this was because I was halfway through the upgrade when I thought about creating a USB version just in case, but I gave up since I was short on time (I completed everything before going to bed). I do have Windows 10 installed on a USB stick recently.
As for the BIOS version, CMD indicates 2.20. This is the latest BIOS version available according to ASRock’s page at that time, along with the beta one which I ignored.
So... it seems I likely made an error when saving or exiting from the BIOS, so I assume the next step is to clear the CMOS...? I performed a jumper using a screwdriver (everything unplugged, ensured no power remained) a few days ago to reset the CMOS, but it didn’t fix the issue because the problem persisted. Therefore, I might need to remove the battery to reset the CMOS and then try the whole process again, possibly using Windows 11?
I’ll wait for a response before taking any action.
Here what occurred in this situation?
I had to experiment with the BIOS during the installation of Win 11 on a brand new system. I also experienced several display issues. I spent three Resurrection spells from the screwdriver’s tool, trying to clear CMOS. Luckily, it resolved and the screen returned. Still, I decided to create a Win 10 installer and upgraded to 10.11.
It wasn’t crucial, but I remember clearly that adjusting settings like CSM, TPM, and Secure Boot left me without a display on either the iGPU or dGPU. It was quite frustrating because none of the changes I made affected the screen, yet it did.
Could you describe the steps you took?
Also, when there’s no display, does your computer boot into Windows or remains in UEFI/BIOS?
You should know that Win 11 needs TPM but not Secure Boot. Secure Boot doesn’t need to be turned on—it just needs to be possible. It must be supported by the motherboard or UEFI.
CSM is also unnecessary to enable.
The reasons why these settings disrupt the display are unclear to me.
If you manage to reset CMOS, restart BIOS settings, save and exit, then try accessing BIOS without a display. Use keyboard shortcuts to reset, then save and exit. Check your motherboard manual for guidance.
I would verify if your setup uses an MBR instead of GPT partitioning, as this could indicate a MBR partition limit issue.
I don’t remember all the actions i performed, but the video i shared helped me resolve the platform key message that prevented TPM activation. The clip is about two minutes long, with information presented every minute. Mostly i turned off a setting in the BIOS, activated secure boot, then reverted it and saved, just as shown in the video. However, it’s possible the video might have had an error, since the final step asked to verify secure boot status on system info—yesterday it was off, which should have been on after I enabled it and the PC health app showed green. I think if I could get the BIOS to show again, i could retry the process and fix the issue. But to restore the display, i suspect i need to remove the battery, although i did work on the pins for a while without fixing the problem.
I consistently don’t see a display for UEFI/BIOS all the time. When i power off my PC completely, i don’t see any windows output. I attempted it today, turned it off yesterday, and today i simply cut the power source on the PSU (button), waited 20 seconds, then turned it back on and restarted my PC—then the display appeared only when Windows loads or updates. The screen flickers occasionally. I’ve tried using HDMI or IG-PUGA as alternatives, but nothing shows up. It seems the issue might be with the BIOS getting confused with the settings.
My old ASRock motherboard had a CMOS clear button that really helped, whereas this one uses just two pins—either with a screwdriver or by removing the battery. Removing the battery requires taking out the GPU, and i have some anxiety about handling those components again. I’d prefer to avoid touching anything until further notice to prevent more problems.
I won’t start any changes until the weekend, as i don’t want to disrupt workdays and get frustrated. I’ll update the thread afterward with what i tried and whether it worked.
I don't use partitions on my drives; the last time I did was with Windows XP over ten years ago.
My main SSD is quite old and slow, but it handles the OS and occasionally runs one or two demanding games. I usually leave 40-50gb free space out of its 222gb capacity.
I also have an even older 1tb HDD, which stores most of my random data, followed by a faster external SSD that holds the heavier games, and two external HDDs for storage and backups. These external drives are old console drives that have been gathering dust from previous generations (PS4/Xone).
Since I no longer use those consoles...
Unusual problem might be due to a boot setting such as Fast Boot. It bypasses the BIOS entirely. You could attempt to restart the machine directly into UEFI/BIOS. A unique shutdown feature in Windows will restart the computer straight to BIOS, without needing any keyboard keys or a Windows boot. You won't need a Windows interface at all. Don't expect to have to take out the battery. There are alternative methods to reset CMOS, such as using a screwdriver or removing capacitors from the power supply unit.
