[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

Unresolved Windows 11 BSODs during normal desktop use after clean reinstall (PAGE_FAULT_IN_NONPAGED_AREA, SYSTEM_SERVICE_EXCEPTION, dumps included)

Upvotes

Hello everyone,
excuse my english i prefered chatgpt describing writing this over me

I've been troubleshooting a system that's been experiencing recurring BSODs for quite some time, and after exhausting the troubleshooting steps I could think of, I'm hoping to get some insight from people with more experience in WinDbg and kernel debugging.

System

  • Windows 11 Pro 25H2 (Build 26200.x)
  • Intel Core i9-14900KS
  • ASUS ROG Strix Z790-E Gaming WiFi II
  • G.Skill Trident Z5 RGB 48GB (2×24GB) DDR5-8400
  • NVIDIA RTX 5080
  • Crucial T705 Gen5 NVMe SSD

Summary

The crashes originally started before I reformatted Windows. Because the bugchecks and faulting modules kept changing, I performed a clean installation of Windows to rule out OS corruption.

Unfortunately, the same type of instability continues after the reinstall.

The BSODs are not tied to one specific activity. I've had crashes while gaming, during normal desktop use, and even shortly after boot with nothing significant running.

Besides the BSODs, Windows itself has been unstable:

  • Task Manager occasionally opens and immediately closes by itself.
  • Corsair iCUE crashes every 30 mins or less.
  • Google Chrome also crashes memory acess violation especially during video running on youtube
  • and every windows program almost

I'm mentioning these in case they're relevant to the overall picture.

Bugchecks observed

Before reinstall:

  • MEMORY_MANAGEMENT
  • PAGE_FAULT_IN_NONPAGED_AREA
  • SYSTEM_SERVICE_EXCEPTION
  • KMODE_EXCEPTION_NOT_HANDLED
  • INTERRUPT_EXCEPTION_NOT_HANDLED
  • ATTEMPTED_EXECUTE_OF_NOEXECUTE_MEMORY

After reinstall:

  • PAGE_FAULT_IN_NONPAGED_AREA
  • HYPERVISOR_ERROR

WinDbg

Across different dumps, WinDbg has pointed to different Microsoft components, including:

  • ntoskrnl.exe
  • WdFilter.sys
  • Ntfs.sys
  • win32kbase.sys

Since the reported module changes from crash to crash, I'm unsure whether these are the true source of the problem or simply where Windows eventually detects the failure.

Troubleshooting already performed

  • Clean Windows installation
  • BIOS updated
  • Latest chipset and GPU drivers installed
  • sfc /scannow completed successfully
  • Disabled XMP and currently running memory at default JEDEC settings
  • Ran the motherboard's built-in MemTest from BIOS after disabling XMP (no errors reported at default settings)
  • Collected multiple crash dumps and Event Viewer logs

Installed software that may be relevant

Some software on the system installs kernel components or low-level drivers. I'm not suggesting any of these are responsible, but I'm listing them for completeness:

  • Aimware cheat
  • VMware

If there are other installed drivers you'd like me to list, I'm happy to provide them.

Files included

I've attached mediafirelink https://www.mediafire.com/folder/kmwabx65bxpa6/DUMPS

  • MSINFO32
  • System and Application Event Logs
  • driverquery.csv
  • systeminfo.txt
  • dxdiag.txt
  • WinDbg outputs

Thanks in advance for taking the time to look at it.

New MB and CPU (Intel -> AMD). Operating System question.

Upvotes

My old setup was running on Windows 10 and since I switched to AMD I was having the BSOD. I found my old windows 10 USB drive and tried reinstalling it. I chose the option to keep my old files but when I choose that option I get this notice: “The upgrade option isn’t available if you start your computer using Windows installation media… If a copy of windows is already installed on this computer and you want to upgrade, remove the installation media and restart your computer. After Windows has started normally, insert the installation media and run Windows Setup.”

At this point I’m confused as to what I need to do to be able to keep my files and use my computer!

Windows Laptop suddenly became extremely laggy today. SFC/DISM repaired corruption but it's still slow.

1 Upvotes

My laptop suddenly became very slow today. It was working perfectly before, and then all of a sudden almost every application started lagging when opening.

Specs:

Windows 10

Intel Core i5 M450 @ 2.40 GHz

4 GB DDR3 RAM

Vi550 S3 SATA SSD (upgraded from the original HDD)

Symptoms:

Desktop is smooth when idle.

Mouse cursor is smooth.

Opening Chrome, File Explorer, or almost any application causes noticeable lag and CPU spikes.

Browser scrolling feels choppy.

Even YouTube videos have dropped frames and don't play as smoothly as before.

I use NVIDIA GeForce NOW regularly. Until today it streamed flawlessly at 60 FPS with around 10 ms latency. Now it's only streaming at around 30 FPS despite still showing about 10 ms network latency, and the input latency feels much worse than before.

CPU speed stays around 2.38 GHz, so it doesn't appear to be thermal throttling.

SSD response time looks normal in Task Manager.

No unusual background process is using high CPU, memory, or disk.

What I've already tried:

Restarted multiple times.

Tried different browsers.

Disabled browser extensions.

Checked Task Manager for high CPU/disk usage.

Ran sfc /scannow → Found corrupt system files and successfully repaired them.

Ran DISM /Online /Cleanup-Image /RestoreHealth → Completed successfully.

Laptop became slightly better after SFC, but it's still noticeably laggy.

No Windows updates were installed recently.

Has anyone experienced something similar? Could this be an SSD issue, a Windows problem, a driver issue, or failing hardware? What would you check next before doing a clean Windows reinstall?

Lenovo Legion 5i 16IRX9 Repair

1 Upvotes

Hi all, I’m super new to repairing computers so I wanted to ask for help. My damn cats knocked my laptop down from the top shelf in my dining room and bent the hell out of it. The heat sink was bent to hell, the corner of the screen was bent but the display looks alright, and the shell was obviously cracked and no longer useable. I bought a non working, good condition replacement with the hopes I can swap parts over.

My main question is this: what pastes do I need to buy for the CPU sections? I dont know what type the white stuff or pink stuff is. I did, however buy the grey thermal paste already. Is there anything else I should be aware of before I take the non-working one apart so I can start swapping components?

Also, would anyone know if I can remove the keyboard and save it as a spare? Its has a bunch of plastic welds but no screws. Any help would be greatly appreciated.

Solved Computer freezing on update screen

1 Upvotes

Heyyy, so my computer decided that I was at risk of being out of date on updates and forced me to schedule an update last week. So I scheduled one, and turned the computer off because I didn’t feel like dealing with it right then.

I opened the computer yesterday and found out that it didn’t properly turn itself off and kept itself running.

Upon opening it, I was met with the dell startup screen and then immediately taken to the “updates are underway, please keep your laptop on.” screen. And then it buffered for like 5 minutes, so I turned it off and turned it back on, it did the same thing. So I got to the bitlocker screen and then found out that I don’t have access to the microsoft account that the key would be accessed through (it’s a shared computer with my mom and the account information is stored on the computer).

The only other option I was presented with was factory resetting it, and we can’t do that because we have important files on there.

What would be the next best course of action? Would it just be easier to get a new laptop?

Unresolved PC crashes and fans start blasting full power.

My pc keeps randomly “turning off” (screen goes black, no audio, caps lock doesn’t turn on however the lights on the pc are on and keyboard and mouse still lit up) and the fan either blows at max for a second or keeps going until manually turned off with the main button. Happened at first if left alone for too long a couple of days ago, now happened mid game, then when i tried turning it on again it did the same thing immediately. Left it for a minute, tried turning it on and it worked for about five minutes before it died. Any thoughts?

Windows I'm dumbfounded!

1 Upvotes

I had a problem where when I was trying to format a SD card and I thought I formatted my data drives because I couldn't access them, they did not show under my computer. I spoke to a computer tech about it and he asked if I was comfortable removing the hard drive and bring it to his shop or did I want to just bring the whole computer in. I told him him I could bring just the drive in. So I went to look for it and they were not visible from the left side of the computer so I had to open the right side and when I did the two regular hard disks were sitting there in trays. Here's the weird part. Neither were hooked up!! No power cable and no data cables were hooked up. One drive was marked media and the other was just marked 1 TB. So I hooked the media drive back to the mb and power rebooted the computer and all my media I thought I lost was there! So I thought I would hook up the other drive and the was no data cable. I had to rob a cable from my old computer to complete the hook up. Rebooted the computer and low and behold the drive showed up under my computer and I could access the files on that drive. Weird! My question is, how was I able to use the drives without them being hooked up?? My son said that maybe the computer guy set them up as virtual drives. I don't have a clue. The physical drive with the media on it, I did notice the some videos I know I added to it before all this were not on there. I'm dumbfounded. Windows 11 home edition.

a few things i have tried:
restarting PC/Shutting PC completely off/unplugging
resetting the internet itself
flushing DNS and renewing IP
reinstall network drivers
tried to update drivers
i tried to run the troubleshooter for internet but i dont have a memorized wifi so it wont let me do it.
i should also mention my computer is old, but its never had an issue like this before. it runs on windows 10 and when i first got it (i got it from a friend) it didnt show any available wifi at all so i got an external wifi adapter and had been working perfect until now. i also have tried moving the antenna to different USB ports but that also didnt work. also ethernet is not an option
im about to turn my monitor into a wrist watch

Mouse auto-clicking

1 Upvotes

Hello, I've been having issues with my laptop recently where my mouse keeps auto-click/lockimg into place on the bottom of thr screen where my taskbar is. This has been gping on for days now and I've already tried everything I cpuld think of which I'll list below; The laptop I have is a Lenovo IdeaPad however I use this to run my DAW softwares, Blender, Unity, and a couple other softwares for developement, and yes I play games on it too. My laptop is updated to the latest windows software so I had no issues with the mouse until just recently. These are the solutions I've already tried to fix the issue but were unsuccessful for me;

• I've unplugged the mouse and shut it off (I use a wireless mouse). I've even taken the battery put just in case but the issue still presists with no change.

• I've cleaned the track pad, mouse sensor (even took it apart to make sure nothing inside was interfereing with it), and even the screen since it uses smart touch/tluch screen features. The issue still presists with no change.

• I've uninstalled all mouse drivers, restarted my laptop, let it install the moyse drivers automatically (I did this through what I had searched up and it was instructed to do this method if this was the case). I went to my mouse driver to check for any updates, The issue still presists with no change.

• I ran a malware scan twice to check if it was a virus tampering with the moyse controls but it came back clean. I did a full scan just in case as well but even that showed up clean. I looked into my drivers a second time but nothing seemed out of the ordinary.

• I factory reset my laptop to see if it'd help and ended up losing files, project files, and documents in the process (some important documents as well). I even made sure to run another scan just in case. I cleaned my mouse sensors a second time, clean the touchpad again, made sure the screen was clean as it uses a touch screen feature, and even when all that was said and done the issue still presists with no change.

I don't know how to fix this issue anymore so I am turning to this as a last resort. I even recorded it jusf in case unfortunately because this is a new account and I had just joined this reddit I can't post it here. Is this something that I'm looking at but I am unaware of? Did I blindly miss something I could have easily fixed?

My monitor shows this bar of flickering lines sometimes. I've noticed it's mainly whenever any media is playing but sometimes it just happens when I'm scrolling on a page. From what I've seen, it seems to show up more often when I'm on dark mode for any application. I've tried updating drivers, checked temps on my hardware (they're fine), and have updated everything to the latest versions. I'm currently waiting for a new DP cable to arrive to see if it's a cable issue but I'm not sure. Does anyone have any idea what it could be?
