Hi, thank you for updating. I am glad that it is now all good.
PC shuts of randomly and restarts, dGPU issue (RTX 4090)
Hi togehter,
I resently bought a used RTX 4090. The joy was short-lived as PC startet to just shut off (blackscreen without any errorcode). As the GPU was the only thing that I upgraded I am led to believe that thats what causes the issue, simply because my previous setup never blackscreened. My power supply has enough headroom to support the 4090, so this shouldn‘t be an issue either. I already updated the drivers and reinstalled them multiple times but it just keeps happening. I have read something about „minidump“ files, sadly I don‘t know what to do with them. Can anyone here help me out?
Thanks in advance!

2026-02-14T14:50:34.04+00:00 Hi, thank you for patiently waiting. Upon checking and analyzing the DMP file you have, an error is found in nvlddmkm.sys, which is your Nvidia graphics card driver. To fix the issue, kindly follow the steps below:
Let us run a clean installation of the Nvidia driver. This differs from performing DDU or updating the driver, as it will remove all existing entries and replace them with compatible ones. Kindly follow the steps from the link below:

Watch out for ads on the site that may advertise products frequently classified as a PUP (Potentially Unwanted Products). Thoroughly research any product advertised on the site before you decide to download and install it.
Additional note: If the issue persists, I suggest removing the GPU and placing it into another PCIe port available (This is only applicable if you are using a Desktop PC or an External GPU). However, if all fails, I suggest contacting a local technician to physically check the device for any hardware-related issues.

Based on your inputs, it seems that the GPU is experiencing power loss. Have you tried to use a different PSU just to check?
While waiting, can you upload and share the Minidump files on your PC? To do this, kindly follow the steps below:
Press Windows key + E (To open File Explorer)
Click "This PC" > then follow the file path:
C:\Windows\Minidump
Copy the Minidump files and save them to another location, like the Desktop or Documents.
Then please upload it to Cloud storage like OneDrive or any cloud storage you are using, and please share the shareable link here.
To upload and share the link using OneDrive:
Go to this link: https://onedrive.live.com/, then upload the file.
Then, provide the shareable link by following the steps from this link: https://support.microsoft.com/en-us/office/share-onedrive-files-and-folders-9fcc2f7d-de0c-4cec-93b0-a82024800c07

Q&A Assist2026-02-13T21:22:21.5+00:00 AI generated content. This question contains an answer created with AI from Q&A Assist. Learn moreIt sounds like you're experiencing a frustrating issue with your new RTX 4090. Since your power supply has enough capacity and you've already updated the drivers, here are some troubleshooting steps you can take:
- Check for Overheating: Ensure that your GPU is not overheating. Use monitoring software to check the temperature of the GPU during use. If it’s running too hot, consider improving your case ventilation or cleaning dust from the fans.
- Power Supply Issues: Even if your power supply has enough wattage, it might not be delivering stable power. Consider testing with a different power supply if possible.
- Check for Hardware Conflicts: Sometimes, new hardware can conflict with existing components. Ensure that all components are seated properly and that there are no loose connections.
- Minidump Files: Minidump files can provide insights into what might be causing the crashes. You can analyze these files using tools like WinDbg or BlueScreenView to identify the specific error codes or drivers that may be causing the issue.
- Run Hardware Diagnostics: Use built-in diagnostics tools or third-party software to check the health of your GPU and other hardware components.
- Test in Safe Mode: Boot your PC in Safe Mode to see if the issue persists. This can help determine if the problem is related to drivers or software.
If the problem continues after trying these steps, it may be worth considering that the GPU itself could be faulty, especially since it was purchased used.
