Question No display after enabling TPM and upgrading to w11

[zeus9860]

Howdy, once again i visit these forums to request some knowledge on potential solutions to fix my hardware problems.

Full specs:
-b550m pro 4 asrock motherboard
-r5 5600g
-2x16gb 3200mhz ddr4 ram (or used to be at 3200mhz when i messed around after buying the hardware 2-3 years ago, it seems to have gone back down to 2133mhz after a quick look at task manager, idk why)
-asus gtx 1080ti
-corsair rm 750

So, what i've done as far as i remember:
-bios update for an eventual w11 upgrade (update was years ago, had no issues. But windows 11 upgrade was 5 days ago)
-enabled TPM on bios with W10, i had to mess around to be able to active TPM on bios as the option was greyed out for me. After managing to enable TPM, i saved and rebooted my PC, i noticed my boot display was gone... but i still had windows display (loading/update screen onwards)
-decided to move to windows 11 in hopes the problem would go away, but it did not. Windows 11 displayed just fine after upgrading day 1, i believe the second time i launched my PC it worked fine too, but 3rd time started giving display issues. So now i have the boot display issue from enabling TPM (honestly i can live without it as i do intend to make a new build in 2-3 years), but the most important part is not having display properly on loading/update screen onwards in windows. Whenever i shut down or restart, this issue happens.

I've tried clearing CMOS using the 2 jumper pins with a screw driver first time i had the issue, it fixed the problem (not the boot screen issue). I've noticed that display works "fine" if i completely shut down the system and remove the PSU cable for like half a minute and press the power button for 5 seconds or so. Then i plug it in and power it back up. After doing this, my screen starts flickering for a bit (on and off quickly), it goes away after a few seconds and it seems to stop flickering early if i gently hold the DP connector on the GPU. I only have this 1 DP cable that came with the monitor, but i don't think the problem is the cable as the flickering only happens on initial display and then works fine nonstop.

So now i am wondering what is going on exactly, i simply tried moving from windows 10 to windows 11, lost boot display when enabling TPM for windows 10 and 11, but then i also lost windows 11 display on my 3rd boot on windows 11 and the only "quickway" of fixing the problem that i figured is cutting the power source for a bit and plugging it back in.

Computer was working with no issues prior to enabling the TPM stuff some days ago...

Upgrade to windows 11 they said, it will be fun they said... -_-'

Any suggestions?


PS: This is my 2nd asrock mobo, my previous one from 2012 had similar issues when i moved from windows 7 to windows 10, supposedly on the specs pages from asrock, my previous mobo was not "compatible" with windows 10, or just partially compatible or something, it worked fine, except for the boot screen which was gone (i could still load into bios spamming keyboard key, but yeah i would only get image display from loading/update onwards), which happened AGAIN when moving from windows 10 to windows 11 with this new motherboard, so i am starting to believe this is an ASROCK issue with the display going faulty after upgrading OS. Except this time around it is impacting display after boot as well.

If it was greyed out, how did you enable it?

If you upgraded to Windows 11 using the internal upgrade path, then you're advised to recreate a bootable USB installer for Windows 11, then perform a clean install.

For the sake of relevance, what BIOS version are you on for your motherboard?

Maybe greyed out is not the best description i could have given. I did this TPM change like 1-2 months ago or so, so the details are coming back to me slowly. This is the video i used to enable the TPM:

View: https://www.youtube.com/watch?v=03Zjo-RyYbI



After rewatching it, i might have messed up the process. As secure boot state is off under system information while in the video it is on. I spent a couple of hours trying to find this video again...

As for the bootable usb installer, i thought about doing that back then, for some reason i sticked with the installer assistant. I think it was because i was 30 minutes into doing the upgrade and then i thought about making a usb bootable version just in case but then gave up on the idea as i was short on time (did all of this before going to bed). I do have w10 on a usb stick that i used for a clean install not long ago.

As for the BIOS version, CMD states 2.20. It is the version that adds support for windows 11 based on asrock's page, back then this was the most recent BIOS version i had available, along with the beta one (which i ignored).

So... it is very likely i screwed up one of the options before saving and exiting from the bios, so i assume all i have to do is to clear the CMOS...? I did the jumper with a screwdriver (everything unplugged, made sure there was no power left) a few days ago to clear CMOS but it did not reset anything because the problem is still there. So, might have to remove battery to clear CMOS in hopes it goes back to normal and then retry the entire process but while using windows 11?

I'll wait on a reply before doing anything.

i had to mess around to be able to active TPM

What happened here?

I had to mess around in BIOS when trying to install Win 11 on a fresh build. Also lost display several times. I wasted three Resurrection spells from the screwdriver wand of CMOS clearing. Thankfully they worked and and i got display back. I had had enough though, made a Win 10 installer and upgraded 10 to 11.

That is not really important but i do remember very well that messing with CSM, TPM, and Secure Boot left me with no display on the iGPU or dGPU. It was really frustrating because none of the settings i changed affected display, but it happened anyway.

Could you recall the steps you made?
Also, when you get no display, is your PC booting to Windows or does it sit in UEFI/BIOS?

You should know that Win 11 requires TPM, but not Secure Boot. That is, Secure Boot does not have to be enabled, it just has to be possible to enable it. It just has to be supported by the motherboard/UEFI.
CSM is also something you don't need to enable.

Why these settings mess up display is beyond me.
If you manage to clear CMOS, reset BIOS settings, then save & exit. And if you can get to BIOS without any display, try to use keyboard shortcuts to reset settings, then save&exit. Look in your motherboard manual.

One thing I would check is whether your installation is on MBR rather than GPT partitioning. you may be hitting a partition limit of MBR.

I can't recall all the steps i did, but the video i linked is what i used to overcome the platform key message that was not allowing me to enable TPM. Video is 2 minutes long and the information rolls in at 1m. But for the most part i switched off an option in the bios, then enabled secure boot, then went back to switch the option back to what it was before then save and quit, just like in the video. However it could be possible i messed up something from the video as the final step on the video is to check if secure boot is on system information, which i did yesterday and it is off (it should be on because i did enable it and pc health app was green after doing this). So i would assume if i could get BIOS to display again, i could redo the steps and fix the problem. But to get the display back i assume i have to remove the battery, correct? As i did screwdriver on the pins for a while and it did not fix the display issue for BIOS/UEFI.

I get no display for UEFI/BIOS 100% the time. I get no windows display if i do not cut the power completely after powering off my PC. I tried it today, turned it off yesterday, today i just cut the power source on the PSU (button), wait 20 seconds, turned it back on and powered my pc, display works ONLY when windows kicks in, so when it says "windows is loading" or when windows is updating, that is when i get a display. Image flickers for a bit at times, but not all the time. I've tried using hdmi or igpu when the display is not working, it still does not show anything. It all seems to pinpoint towards my BIOS being confused with the settings...

My old asrock mobo had a button for CMOS clear, it actually helped a lot, this one is just the 2 pins with a screwdriver or removing the battery it seems. But to remove the battery i have to remove the GPU, and i have PTSD from removing GPUs and putting them back on in my old mobo, so i want to avoid touching any of that stuff as much as possible to avoid new issues coming up.

I won't be doing anything untill weekend though, i don't want to mess around with stuff during work days and potentially get frustrated with this thing as i am also short on time to do any experiments right now, gonna wait untill work is over and then mess around. I'll update the thread by then with whatever i attempted to fix and if it worked or not.

I don't do partitions on my drives, last time i did any of that was with windows XP over a decade ago.

I have the main SSD, which is a bit old/slow but runs the OS and 1 or 2 heavy games at times, i usually keep 40-50gb free space, it has 222gb total. I also have an even older 1tb HDD, which is where most of the random stuff goes in, then an external SSD with 2 tb which is much faster than the main one and is where most of the heavy duty games go into. Have 2 external HDDs for storage/backups, these external drives are all console drives that were left collecting dust from the previous generation (ps4/xone). Since i don't use those consoles anymore...

Strange issue. Maybe you set some boot option like Fast Boot or whatever they call it. It skips BIOS completely.

You can try to restart the computer directly into UEFI/BIOS. There is a special shutdown option in Windows that reboots the computer straight to BIOS, no keyboard key needed, no Windows boot. Just BIOS.

You shouldn't have to remove the battery. There are other ways to clear CMOS, like the screwdriver or emptying capacitors on the PSU.
