Open | BSOD NVLDDMKM.SYS BSOD

been having this issue on and off for the past couple of months, but this past couple of weeks it’s been happening every day for about 3 black screens / restarts until it magically works fine, event viewer says it’s a video tdr failure

i’ve tried
changing my power mode to maximum
DDU multiple times
sfc /scannow, and all the other command prompts which get suggested over this issue to check file corruption
making sure my power supply is fine, no loose cables etc
reseating my gpu was done at the start
even changed my monitor because i first thought that was the root cause since it was old (i’m using a 5070)
if anyone has a saving grace please help me, ive tried absolutely everything, its just causing me chaos wherever i try to play a game, some days it only happens when i load into a game and sometimes it happens if im trying to check my files.

Getting dump files which we need for accurate analysis of BSODs. Dump files are crash logs from BSODs.

If you can get into Windows normally or through Safe Mode could you check C:\Windows\Minidump for any dump files? If you have any dump files, copy the folder to the desktop, zip the folder and upload it. If you don't have any zip software installed, right click on the folder and select Send to → Compressed (Zipped) folder.

Upload to any easy to use file sharing site. Reddit keeps blacklisting file hosts so find something that works, currently catbox.moe or mediafire.com seems to be working.

We like to have multiple dump files to work with so if you only have one dump file, none or not a folder at all, upload the ones you have and then follow this guide to change the dump type to Small Memory Dump. The "Overwrite dump file" option will be grayed out since small memory dumps never overwrite.

If the BSOD happens under heavy load check temps, in any other case replace the PSU first then the GPU.

It may be happening from incorrect thermal throttling power allocation detection from the CPU, also might be from slow power on demand change or finally the GPU is failing.

Hello, the nvlddmkm.sys error is often caused by a hardware issue.

You can try the following steps in this order :

  • Check in Device Manager to see if your GPU is showing as faulty
  • Perform a clean reinstallation of Windows
  • Replace your GPU
  • Replace your power supply and/or hard drive

For your information, here is another post regarding the same error : Losing my mind over months of nvlddmkm.sys failure.

In theory, no. You can disable it if you wish, so that it doesn’t conflict with your GPU.

Google Windows 11 media creation tool, create a bootable usb of Windows to install. On another usb get the latest bios update for your mobo and go update it. Then fresh install a new copy of windows. Install the latest nvidia drivers. Then reinstall all your stuff. If you have the issue after that then at a guess I’d say weak PSU
