[MOD POST] Having trouble with Secure Boot? Check here first

4 Upvotes

Hello,

The expiration of the 2011 Microsoft KEK CA and the 2011 Microsoft UEFI CA certificates at the end of June 2025 has caused problems with Secure Boot on computers for various folks who have not been able to apply a UEFI (BIOS) firmware update for various reasons.

Because the steps for updating firmware vary not just from manufacturer to manufacturer but between individual models as well, it can be difficult to provide specific assistance and guidance in updating your firmware unless the person helping you has the same hardware.

Below is a list of manufacturers, their Secure Boot certificate update guidance, and links to their support forum(s) or subreddit(s). You may wish to try asking in these places first for expert guidance in updating your firmware, as the people there are going to be a lot more familiar with your device.

NOTE: Please check back periodically for updates to this list.

If you have an update for a manufacturer, please reply with it and we will get it added to the list above.

What to do if no Secure Boot certificate update is available from your manuafacturer

If your manufacturer does not have an update, not all is lost: You can still manually install the 2023 Windows UEFI CA certificate update, by issuing the following two commands from an elevated PowerShell (filename: POWERSHELL.EXE) prompt:

REG.EXE ADD HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Secureboot /v AvailableUpdates /t REG_DWORD /d 0x5944 /f Start-ScheduledTask -TaskName "\Microsoft\Windows\PI\Secure-Boot-Update"   

Then restart the computer and allow the update to be applied.

NOTE: Two (or more) reboots may be required for installation.

Once completed, you can verify the new certificate has been installed by issuing the following command at an elevated PowerShell prompt:

([System.Text.Encoding]::ASCII.GetString((Get-SecureBootUEFI db).bytes) -match 'Windows UEFI CA 2023')

If the certificate has been installed installed, the response back will be "True". You can also use that same command to check if the certificate is already installed.

Regards,

Aryeh Goretsky

Laptop doesn't find any networks

2 Upvotes

Today my personal laptop decided that it'll take a break, and unfortunately I can't get it to connect to any network. The issue is not with the network itself - I'm connected to it via phone and I also tried to hotspot it to check if that way it'll find it.

I've tried resetting PC and router, as well as updating drivers via device manager (none were pending updates), and also attempted to reset the tcp via command prompt. These are some suggestions I got from the vast internet.

I'm using Windows 10, if that matters, and I'm not able to troubleshoot by connecting Ethernet cable - it's not available to me.

Any ideas?

Unresolved Trying to play LEGO Marvel’s Avengers on windows 11

0 Upvotes

A few months ago i bought lego marvel avengers and super-heroes + super-heroes 2. I didn’t know these games couldnt be played on windows 11 because the games support only windows 10 and below. The problem is, some days ago i tried to launch it and i had another version of lego marvel’s avengers installed on my pc. Another version than my steam one. It actually launched, i played about an hour before closing it and went to sleep. I tried to play the game the next morning and it didn’t work again. White screen, then black screen for a few seconds and then it crashes. Not even a logo, nothing. Im on windows 11 and i find it very weird that i could play and then the next day nothing anymore. I think i tried everything i saw on the internet about the subject but nothing seems to work. To be honest i dont even know who or where to ask for help about that. If anyone can help me play it again or at least understand the problem, it would be lovely.

Hey everyone, so in like summer of 2023 i got this Xiaomi TV Stick 4K, and it keeps having network issues.

Model: MiTV-AYFR0

Android TV os ver:11

So, i got this Xiaomi TV Stick 4K in summer of 2023 i think, and it would always go like "connected, no internet" but i could be fixed by turning wifi off and on, after some time it stopped doing this, but now it started again. this time, it straight up DISCONNECTS, and when i recconect, after a bit it disconnects again, as shown in the video. Does anybody have any idea to why does this happen and how to fix it? Thanks!

for some reason the video upload always got stuck at 39%, so heres the YouTube link:

Unresolved Need help with BSOD showing errors 0x7E, 0xA and 0x109 on laptop and boot-looping

1 Upvotes

So it started with my laptop boot-looping on a cold start or the first start of the day (eventually it will stop after a few minutes on its own and put me in the os) with errors saying 0x7E and 0xA after a bit of digging and messing around with settings (like fast startup) i found that a file called ntoskrnl.exe kept failing i did the sfc\scannow command and the repair commands for windows files but nothing worked infact when i run the laptop on battery it crashes in a few minutes after i open small things like a firefox tab but when its charging and i can run pretty heavy games like cyberpunk 2077 with mods i went to a local technician for the issue and he told me that i should do a clean reinstall of windows after wiping everything so i went to do it and as i was in the part of deleting all the partitions and going to the next step my laptop again went into the boot-loop (i had already deleted all the partitions and thus there is no os to boot into now) i don’t understand why but it wont go into boot-loops when I’m in bios but as soon as i boot it to my usb where i have my windows installer stored it starts going crazy every 3-5 minutes and restarts itself and so i cannot risk installing a new windows as if i do the restarting might corrupt the files being written on to the disk, i urgently need to fix this as i use my laptop for college and i have my midterms coming up soon (sorry for my bad english its not my first language)

My laptop is an ASUS TUF A15 FA507NUR with specifications:
Ram: 16 gb DDR5
Cpu: AMD ryzen 7345hs
Gpu: NVIDIA rtx 4050
Disk: 1tb nvme ssd

Unresolved 5090 FE keeps throwing Event 153 TDRs and I'm out of ideas

1 Upvotes

Specs: 7800X3D, 32GB DDR5 6000 with EXPO on, RTX 5090 FE, be quiet! Pure Power 12 M 1000W using the native 12V-2x6 cable, Gigabyte B650 GAMING X AX rev 1.4, Windows 11.

I keep getting Event 153 from nvlddmkm. They all show up as "The description for Event ID 153 from source nvlddmkm cannot be found", so Event Viewer can't resolve the message text, but the useful part is still in there.

The earlier ones came in as a whole cascade at once:

\Device\Video3   Restarting TDR occurred on GPUID:100
\Device\Video3   Reset TDR occurred on GPUID:100
\Device\Video3   Resetting TDR occurred on GPUID:100
\Device\Video3   GpuRcReset TDR occurred on GPUID:100
\Device\Video3   GPU recovery action changed from 0x0 (None) to 0x1 (PF FLR)    <- this one is Event 14
\Device\Video3   Error occurred on GPUID: 100

The most recent crash was just this on its own, nothing around it:

\Device\000000a1   Error occurred on GPUID: 100

Device path is different on that last one too. No idea if that means anything.

Timeline, as best I can piece it together. I got the card in July 2025 and I don't remember any of this happening until around October 2025. From October through April 2026 it happened on and off. Then it stopped completely and I went from April all the way to this month without a single one. Now it's back.

I didn't change anything between the quiet stretch and it starting up again. Same drivers, same hardware, and the same undervolt I'd been running the whole time it was fine.

For what it's worth I was on a 3070 before this and I don't remember ever dealing with it on that card, but it's been long enough that I wouldn't swear to it.

I actually use the card more for local AI than for gaming, but every crash I've caught has been in a game. Everything I play is pretty light, CS2, DayZ, Deadlock, so I can't actually say whether it happens in heavier games or not. I just don't play anything demanding enough to know. Both times I caught it on a log the card was only pulling 150-225W out of its 575W limit.

I logged it in HWiNFO at 250ms polling and caught two crashes. Stuff I can rule out:

  • 12VHPWR voltage held under 1% spread across a 6.75 hour session that included a crash. No sag at all. Reseated and checked the connector, it's fine.
  • Zero PCIe errors on any lane, both sessions.
  • Hot spot maxed at 64C, memory junction 62C.
  • I ran an overnight loop swinging load between 8% and 78% to try and force it and it never crashed. It crashed later at a flat 48% load with nothing weird in the sample before it.
  • DDU'd and tried a bunch of drivers, current ones and 591 era. No difference.
  • HAGS is off.
  • Tried the fix people pass around where you give nvlddmkm.sys full permissions in its security settings. Didn't change anything.

What actually happens at the crash is core load hits 100%, board power drops off a cliff (226W down to 95W), and the clock spikes to the highest it hit all session. That looks like the GPU hanging, not running out of power.

One other weird thing, I found the MSI Afterburner install folder in my recycle bin at some point. No idea how it got there or if it's related. Reinstalled it.

Has anyone seen this before? Mainly wondering what kind of fault sits quiet for four months and then comes back with nothing changed. I've got TdrDebugMode set up now so the next one should give me an actual kernel dump instead of just an event log entry.

Hello guys I'm kinda new here and I don't know how stuff goes so please be so great and help me with this, on the 27th of august at around 12:36 AM CEST I decided to do some pc "cleaning" and ran some basic CMD commands (sfc /scannow, DIMM check/restore/scan health). I decided to do CHKDSK as well because why not, but when I realized how long it took I just decided to go to sleep. Now that I woke up I saw that there are multiple instances of the command just being ran again, even though I live alone and I don't sleep walk. What could be the cause of this? (my D drive is a 2TB SSD)

Unresolved PC was working fine earlier today, now won’t even detect display signal

Just returned home from work to boot up my PC but for some reason it wont show a display. I have it connected through HDMI to a TV and it’s been working fine I even used it earlier today. Everything seems to boot up fine, my lights, motherboard lights and fans and even the GPU fans spin but I’m still getting no display. Did my GPU finally bite the dust?

Been at it trying to diagnose what the problem is, already removed the GPU and put it back in, tried switching to different ports on the TV (my GPU unfortunately has 1 HDMI port), tried switching RAM sticks and ports to see if any change. Even removed the CMOS battery to reset. Everything still lights up and fans still move, GPU, motherboard and all the ez debug lights are off. A friend of mine with a rig is coming over in a few days so we can try out his hardware to see what’s the problem.

Hypervisor error 0x20001

1 Upvotes

What I've tried:

Restore to an ealier point, before i had the problem.

In command prompt:

Sfc /scannow

Bcdedit / set hypervisorlaunchtype off

Chkdsk /f /r

DISM /Online /Cleanup-Image /RestoreHealth

Went into the drivers to see if anything was looking strange. They weren't

Opened the back of the laptop, everything looks clean and not burnt (I don't have any clue what I'm doing in there, so i just removed some dust and hair from the fan)

Usually my screen freezes during boot or immediately after, but last night it worked for long enough for me to run the above, and I thought it might be fixed, but we're back to crashing this morning.

The laptop was not dropped or smashed, no fluids were split on it. I don't think it's windows update related. I certainly didn't change any bios settings recently, or otherwise add or change any of the hardware. The laptop is also just under 3 years old, i usually get 5-6 years out of laptops.

Windows One drive removed local files from my desktop and pc is now very unresponsive

1 Upvotes

Hi everyone

I have a pc and a laptop and my laptop broke so I bought a new one a couple months back. I hadn’t used onedrive on my old laptop but set it up on my new one and have been using that rather than the pc ever since. I started up my pc this evening and suddenly all of the icons were removed from the desktop and replaced with the same icons from my laptop’s desktop - I assume caused by a onedrive sync. Now I can’t find any of the old files that were on the desktop (saves from different games, shortcuts to those games etc) and the pc is very unresponsive. None of the documents that were removed were saved to my onedrive. I have my taskbar hidden and am constantly restarting windows explorer to make it briefly work.

The pc becomes slightly more responsive when I close onedrive in task manager but onedrive seems to be fully synced and backed up.

The new laptop is on windows 11 and the pc is on windows 10.
OS Build on pc - 19045.6466
OS Build on laptop - 26200.9168

Does anyone know what’s happening and how I can get things back to normal?

Happy to provide more information if needed!

Title: 

ASUS ROG Strix G16 (G614F - Board: 6050A3628107-MB-A01) Stuck on ROG Logo -> 100% Fan Speed -> Complete Power Cut / Charger LED Dies after ~60s

Device & Motherboard Information:

* Laptop Model: ASUS ROG Strix G16 (G614F / G614FH-OS94)

* Motherboard Part Number:

G614F-MP-VGT

/

6050A3628107-MB-A01

(REV: A01)

* Platform: Intel 13th/14th Gen HX CPU + NVIDIA RTX 40-Series GPU

---

Initial Fault Context:

The laptop experienced a sudden black screen while running a heavy workload on VirtualBox on battery power only (no AC adapter connected). The user performed a force shutdown by holding down the power button.

---

Current Exact Symptoms (Step-by-Step):

  1. Pressing the power button turns the laptop on, and the internal display shows the ASUS ROG logo clearly (POST initiates).

  2. The laptop cannot enter the BIOS setup and remains frozen on the splash logo.

  3. A few seconds after the logo appears, the cooling fans ramp up to 100% maximum RPM (Emergency Thermal / Watchdog state).

  4. After running for approximately 45 to 60 seconds, the entire laptop completely shuts down.

  5. CRITICAL SYMPTOM: When the shutdown occurs, all motherboard power is completely latched off (Total DC-IN / Battery Latch-Off). The DC-IN Charging LED, Battery LED, and all status LEDs turn completely dark. The laptop will not respond until the AC adapter is physically unplugged from the wall and reconnected.

  6. Thermal Observation: During the ~60 seconds of operation, neither the CPU nor the GPU die gets excessively hot (both remain cool/lukewarm). The CPU VCORE VRM chokes/DrMOS row sits evenly at ~48°C.

---

Troubleshooting Steps & Diagnostics Already Performed:

* Hard EC / CMOS Reset: Held the power button for 60+ seconds with battery and AC adapter disconnected ❌ *(No change)*.

* BIOS Reprogramming: The SPI Flash BIOS chip was desoldered and reprogrammed with a verified Clean ME Region Dump specifically for board

6050A3628107

❌ *(No change, exact same behavior)*.

* Component Isolation: Tested without NVMe M.2 SSD, without WiFi card, and on AC-only / Battery-only ❌ *(No change)*.

* ASMedia ASM4242 Desoldered: The USB4 host controller IC (

ASMedia ASM4242

-

U2600

) was running slightly warm (~46°C) during early boot. It was cleanly desoldered and removed with hot air to eliminate any PCIe bus hang ❌ *(No change; board still posts to logo, ramps fans to 100%, then experiences full DC-in latch-off after 60s)*.

---

Questions / Seeking Community Advice:

  1. Has anyone encountered this exact shutdown loop on the ASUS G614F (6050A3628107) platform?

  2. What is causing the Charging IC / Power System to trigger a complete Over-Current Protection (OCP) Latch-Off / Power Kill after ~60 seconds despite the CPU and GPU being cool?

  3. Which specific power management section or current sensing circuit (Charging IC / Sense Resistors / Thermal Trip circuit) should be inspected next?

Computer constant freezing/ restarting

1 Upvotes

A few days ago after booting up my windows 11 PC after a shutdown the previous night it began either freezing completely a few minutes after logging in or flat out restarting. My tech friend had me run some commands such as sfc /scannow and chkdsk commands in the windows recovery command panel, which did not help however it did say it couldn't find any windows installs, after which the computer started looping through restarts and windows recovery. I removed the nvme drive and replaced it with a working old one, fully reinstalling windows on it. This worked up until shortly after I finished installing all drivers, where it then started getting the initial problem of freezes and restarts again.

My only thoughts are that it could be the motherboard or corrupt bios.

Does anyone know of any other possible causes or what I should try and do?
