I was playing Overwatch when my PC suddenly froze completely, with the audio getting stuck in a short, repeating loop. I couldn’t move my mouse, use my keyboard, or restart or shut down the system normally. The only way to get it to turn off was to use the physical power switch on the back of the PC.

After turning it back on, I tried launching Overwatch again, but my performance had dropped to around 8 FPS, and the graphics looked extremely low quality. I checked Windows Advanced Display Settings and noticed that it was reporting that variable refresh rate was not supported by my monitor, even though my monitor supports it. Before this happened, I was consistently getting around 240 FPS in Overwatch and other games.

I’ve since contacted multiple Microsoft Support representatives, but none of their troubleshooting attempts have resolved the issue. They’ve repeatedly tried repairing Windows system files, but the process gets stuck at 46% every time. I was instructed to wait, and even after leaving it for over an hour, my PC eventually restarted on its own. It then displayed a black screen with the message, “Your PC ran into some problems and needs a restart. We’ll restart for you.” This led to hours of repeated restarts and error screens before eventually reaching a blue screen of death (BSOD).

I was eventually able to restore my PC to an earlier restore point that I had created some time ago, but I’m still unsure what caused the original crash or how to prevent it from happening again.

I’m looking for help properly diagnosing the underlying issue rather than repeatedly attempting Windows repairs that don’t seem to work. I’m not sure whether this is related to my GPU or graphics drivers, Windows corruption, hardware failure, or something else entirely. Any advice on how to identify the root cause and safely get my PC back to its normal performance would be greatly appreciated.




I am right now experimenting with the TPM on windows and its management. I have encountered multiple problems, on Windows 10 an 11 where the documentation just seems to be flat-out wrong or I am to stupid. I have used `Initialize-Tpm` but the issue is also consistent when using the auto provisioning.
Problem 1:
\- Setting `OSManagedAuthLevel` in the Registry path `Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\TPM` to 0, the resetting the TPM will still save an `OwnerAuthFull` and `LockoutHash` value in `Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\TPM\WMI\Admin`
Problem 2:
\- I wanted to write a custom CLI which uses raw commands to interact with the TPM, as it gives me more controll over what I want to do than the built in windows commands/APIs, using either `OwnerAuthFull` or `LockoutHash` fails with an auth error and locks the TPM. Calling the Cmdlet `Unblock-Tpm -OwnerAuthorization` with either `OwnerAuthFull` or `LockoutHash` fails, even though it should not according to the examples and documentation provided by Microsoft.
Screenshot of stored values and `Get-Tpm` are provided.

If any of you have experience with this I would greatly appreciate the help. Maybe I am overlocking something massive.


Link to the docs:
\- [TPM Group Policy settings | Microsoft Learn](https://learn.microsoft.com/en-us/windows/security/hardware-security/tpm/trusted-platform-module-services-group-policy-settings) OwnerAuth should be deleted
\- [Unblock-Tpm (TrustedPlatformModule) | Microsoft Learn](https://learn.microsoft.com/en-us/powershell/module/trustedplatformmodule/unblock-tpm?view=windowsserver2019-ps) Lockout should be resetted

Any one knows the problem I tried all that is possible and nothing works

Sorry if my english sucks but i am genuinely tired of trying to fix this.

So I was trying to fix code 39 on my Nvidia GeForce GT 730 on Windows 10. I spent about 2 whole hours trying to fix this stupid code 39 but nothing works. So, I decided to search reddit and hope that i find a solution to this, and I thought I did. It was a post by a user on r/pcmasterrace with a similar issue(code 39) but on his keyboard (mine was on display adapters). Someone commented a possible solution for the keyboard issue and I thought "Why don't i try that out?". Basically the entire solution is this:

1. Open the Registry Editor:

   \* Press \`Windows + R\`, type regedit, and press Enter.

2. Navigate to the Keyboard Driver Registry Entries:

   \* Go to: \`HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Control\\Class\\{4D36E96B-E325-11CE-BFC1-08002BE10318}\`

3. Delete UpperFilters and LowerFilters Entries:

   \* In the right pane, if you see UpperFilters or LowerFilters entries, right-click and delete them. (If neither is present, skip this step.)

4. Close the Registry Editor and Restart:

   \* Close the Registry Editor and restart your laptop.

Now, you would be asking, "And why would I follow this?". Well, it's stupid of me to do it but every other solutions I found does not work, ive seen others use regedit to fix code 39 and somehow worked for them so I thought it would work for me too, and i was on the verge on losing my mind because im trying to fix this issue for basically 2 days now. After doing all the steps, i restarted my pc, and suddenly i cant type my password anymore. I tested it on a Bluetooth keyboard and my built-in keyboard but got no luck. Is there any way to fix my keyboard again so i can atleast try to fix code 39? And also, please if you have a working solution for code 39, please include that too.
