My HP All-in-One PC is currently running Windows 11 24H2 and has been since around this time last year. Since last year, i have been experiencing intermittent lockups, where the PC freezes and the only way to get it going again is by pressing the power button off and then on again, which i never like doing. I have been working from home since June and now notice these lockups a lot more frequently. There is no pattern to when they lock up. Sometimes, i can go all day without a lock up, sometimes a few hours but yesterday, twice in half an hour and 5 times in total throughout the day. Reading online, there are reports that 24H2 can cause lockups, PC screens to turn black for a few seconds and then come back on, and also BSOD. I have experienced all 3 of these problems. About one month ago, i installed a completely fresh version of Windows 11 24H2, thinking that might cure it, but it didn't. Of course at the time, i was not aware that 24H2 could be the problem otherwise i would have reinstalled 23H2 instead. People who have reported similar problems to mine, have backdated to 23H2 and not seen lockups, black screens or BSOD, but i don't want to have to go through the long process of installing 23H2 and then reinstalling all my software packages. Are there known problems within 24H2 that could be causing lockups, black screens and BSOD? If there are, when are they likely to be fixed? If there are not, can you suggest anything that might be causing the problems because it is becoming increasingly frustrating, trying to work only to have the PC lock up at crucial moments.

Before the install, i was experiencing intermittent lockups and black screen flashes for a few seconds and very ocassionally, BSOD, although i have not experienced one of those for a while. In the last 20 minutes, my PC has shut down and rebooted twice. Both times it has saved a minidump in the Windows - Minidump folder, so when you are back online, drop a message in this thread, and i'll send them onto you. I'll be back online from 8am Friday UK time. 0 comments No comments Sign in to comment Add comment With reference to my 2 previous messages, my PC is now even more unstable than it was before i ran the fresh install of the graphics driver.

Update: After the driver installation, my PC was running okay for about 3 hours, then i received a black screen for a few seconds before my screen came back on. Around 9.30pm, my PC locked up again. I have checked the Minidump folder, and there is still just the one file in there from 4th September, which was the one i sent to you a few days ago. 0 comments No comments Sign in to comment Add comment Update: After the driver installation, my PC was running okay for about 3 hours, then i received a black screen for a few seconds before my screen came back on.

Alan • 20 Reputation points 2025-09-18T13:16:52.86+00:00 Hello David, Thank you for the details above. With the internet disconnected, I've used the DDU tool, removed the Nvidia driver in Safe Mode and then reinstalled the previously downloaded driver from the HP website link you provided. In my Device Manager, it still shows up as Nvidia GeForce MX350 - Driver Version: 30.0.14.7262 - Driver Date: 07/11/2021 which is a little concerning because the HP site shows the driver date as March 10 2022. There is no revision number in Device Manager like there is on HP site (Rev.C). I'll see how it runs for the next couple of days and if there are any lockups, i'll get back to you with another message. I've had 2 lockups today, before the reinstall, so hopefully, the new installation cures the problem. I've checked the minidump folder after this mornings lockups (prior to the new install), but there is still only the one file which i previously sent to you. 0 comments No comments Sign in to comment Add comment Thank you for the details above.

However, depending on the cause of the crash, the system may sometimes fail to create minidumps, which in some cases can make diagnosing the problem more challenging. The minidump indicates the driver " nvlddmkm.sys " as the cause of the crash. This driver belongs to your PC's Nvidia graphics card. I suggest performing a clean install of the Nvidia driver as instructed below. Download the latest driver for your graphics card from the computer manufacturer's website. Then, use the free DDU tool to remove the current driver. Then, install the latest driver using the installer you downloaded. I suggest disconnecting from the internet during the entire procedure. (Turn off Wi-Fi or disconnect the Ethernet cable.) DDU : https://www.guru3d.com/files-details/display-driver-uninstaller-download.html Nvidia driver download : https://support.hp.com/us-en/drivers/hp-pavilion-27-inch-all-in-one-desktop-pc-27-d1000i/model/2100364216?sku=4J9L0EA Driver name: NVIDIA GeForce Graphics Driver (Windows 11) Version: 30.0.14.7262 Rev.C (You will need to expand the Driver-Graphics category to find the mentioned driver.) (For laptops and All-in-Ones, it is recommended to use the latest Nvidia driver provided by the manufacturer.) (Run the downloaded EXE file and follow the on-screen instructions to install the driver.) If you have the GeForce Experience or Nvidia app installed, disable the automatic driver updates in the application settings. See if the system will work stably after this. If the crash occurs again after doing this, please share the minidump it created. If you need a tutorial for using DDU, I recommend the video below. https://www.youtube.com/watch?v=bP-2B14Nckw Feel free to ask back any questions.

I'm David, and I'm happy to help you. These behaviors can occur for several reasons. It is necessary to investigate. Please see if your computer created minidump files. These files are in " C:\Windows\Minidump ". (If you don't have a " Minidump " folder, check if it is in the plural " Minidumps ".) Copy any files you have to your desktop and store them in a ZIP file. Then, upload the ZIP file to the cloud (OneDrive), choose to share it, and get the link. Then, post the link to the ZIP file here so I can have a look. I await your reply. 2 comments Show comments for this answer Alan • 20 Reputation points 2025-09-17T15:06:17.02+00:00 Hi David, Thanks for your reply. I've found the minidump folder within C:\Windows, but oddly. there is only one file from 4th September. I'm not sure if it is supposed to create a minidump every time the PC locks up?
