Nvidia GPU is not being recognized anymore after secure boot...

[Seret]

Hey anyone reading this please help me as i may have made a great mistake, so to sum it up, i wanted to play a game of mine however it was stuck and so naturally i looked up how to fix it and one of the top reviews/solutions just told me to enable secure boot, and thus i did, however because my secure boot was disabled(greyed out)

i had to first remove all security keys, then load hp default keys, and then i was able to enable secure boot and then saved and exited from bios, when the homescreen popped up, my pin wasnt working, because well i guess i deleted the security keys but i was able to use my password and sign in,

Now here is the problem, my game was working fine but i noticed lag, i decided to open my task manager and saw that my intel integrated was being used and my nvidia card was no where to be seen, now im stuck here, i did everything i could do for example tried the drivers but the laptop just wont recognize it anymore, i narrowed down the problem and it seems that one of my pci express port, responsible for communication between my gpu and laptop,  has code error 10,   so anyone out their please help me otherwise i would have to reset.

Hi @Seret,
 
Welcome to the HP Support Community!

Thanks for reaching out!

I Understand your concern and don’t worry I’ll take care of this for you.

To better understand the issue, could you please provide a few more details?

• The exact HP laptop model you’re using.
• The version of Windows currently installed.
• Whether the NVIDIA GPU shows up at all in Device Manager (even with the error code).

Here are a few troubleshooting steps you can try in the meantime:

1. Check BIOS Settings
   • Restart your laptop and enter BIOS.
   • Look for options related to Graphics or PCI Express. Sometimes Secure Boot changes can affect how hardware is initialized.
2. Reinstall NVIDIA Drivers
   • Use Device Manager to uninstall the NVIDIA GPU (if listed).
   • Download the latest drivers directly from NVIDIA’s website and reinstall.
3. Run Windows Update
   • Make sure all updates are installed, especially optional ones related to drivers.
4. Reset BIOS Keys
   • Since you mentioned removing and reloading HP default keys, it might help to restore BIOS to factory defaults. This can sometimes re-enable proper hardware communication.
5. Check Error Code 10

• This usually means the device cannot start. After reinstalling drivers, if the error persists, it may be tied to the Secure Boot configuration. Disabling Secure Boot temporarily could help confirm if that’s the cause.

If none of these steps resolve the issue, a full BIOS reset or system recovery might be necessary.

I hope this helps.

Hi @Deep_World

 thanks for responding to my problem.

Now i have tried everything you have tried before, i tried restoring bios to default however still it didnt do anything, i tried reinstalling drivers however nvidia doesnt even know I have the gpu, also I have tried reinstalling the pci express port however it still not working.

Also in my bios I dont have any options regarding gpu because my model(hp pavilion c3xxx) doesnt allow advanced bios settings so I cant access gpu regarded settings.

Now I hope the only way to fix this is by resetting my entire laptop so sir if you have any other suggestions please tell me. Thanks

Hi @Seret,

Thanks for your response. 

I completely understand how  this must feel  especially after trying multiple fixes and still not seeing your NVIDIA GPU recognized. 

so let’s try further troublehsooting before resorting to a full reset.

Here are a few additional troubleshooting suggestions you can try:

• Check Device Manager Hidden Devices
  In Device Manager, click View > Show hidden devices. Sometimes the GPU may appear grayed out, which can help confirm if Windows is detecting it at all.
• Disable Secure Boot Temporarily
  Since the issue started after enabling Secure Boot, try disabling it again in BIOS. Secure Boot can sometimes block unsigned drivers or prevent certain hardware from initializing properly.
• Run HP Hardware Diagnostics
  On startup, press F2 or Esc + F2 to access HP’s built-in hardware diagnostics. Run a system test to confirm whether the GPU is detected at the hardware level.
• Update BIOS & Chipset Drivers
  Visit HP’s support page for your Pavilion model and install the latest BIOS update and chipset drivers. Outdated firmware can sometimes cause GPU detection issues.
• Check Windows Updates
  Ensure all optional updates are installed, especially those related to drivers. Sometimes GPU drivers are bundled with Windows updates.

 If none of these steps resolve the issue, a system reset could indeed be the next option, but ensure all your data is backed up.

I hope this helps.

Hi @Seret,

Thanks for your repsonse. 

If you do go ahead with the reset, I’d recommend:

• Backing up your important files to an external drive or cloud storage first, just to be safe.
• Making note of drivers and software you’ll need to reinstall afterward, especially the fingerprint reader driver we discussed earlier.
• Running HP Support Assistant after the reset to automatically check for updates and drivers it can save time and ensure compatibility.

You’ve been very patient and thorough, and that makes a big difference in getting to the right solution. If you’d like, I can guide you through the reset process step‑by‑step, Kindly do reach out us.
