@DELL-Chris M​ I purchased my Dell computer in December 2021.  The freezing didn't start til about 45 days ago.  Everything was fine until then.  Are you telling me they are not going to validate the Nvidia drivers?  If so this will be the first and last Dell computer I will ever purchase.

I have the same issue and my freezing started about the same time. Purchased my XPS 8940 in September 2021 and am still under the extended warranty until 2025. I have been working with Dell Technical support and so far we have not found a resolution. The forum have lot's of post on the subject.

@Robert Willis​ I know.  It's very frustrating and there should be a fix.  Currently I am trying the display Driver Uninstaller (DDU) to uninstall GPU Drivers.  You can find it here: https://www.dell.com/community/en/conversations/xps-desktops/xps-8940-freezing-again-after-almost-a-year-without-freezing/650c74c82ae49d628fae48ed?commentId=654a47211cca106642d2b4d7.

This shouldn't be that complicated to fix.

After trying everything under the sun, I finally found something that seems to work.  I used the DDU (Display Driver Uninstaller).  Go to https://www.guru3d.com/download/display-driver-uninstaller-download/ and download the DDU.  This is an excellent video that will walk you through the DDU process: https://www.youtube.com/watch?v=GrXSLaSRkw8&t=237s&ab_channel=GTEnglish. Finally you have to update the Nvidia drivers through Dell.  Go here to find the driver for your system: https://www.dell.com/support/home/en-us/drivers/driversdetails?driverid=98dyv.  This site might be helpful as well: https://www.dell.com/support/home/en-sr/drivers/driversdetails?driverid=wr7hf&oscode=wt64a&productcode=xps-8940-desktop.  So far 3 days and no freezing.  Knock on wood.  Best of luck to all of you guys in resolving this.

I tried that and it did not work. Hopefully you may have better luck.

Can you use the NVIDIA Control panel and select Manage 3D Settings and verify what your Power Management Mode is set to? I have been googling Windows 11 Freezing and this issue is not just related to Dell computers and the NVIDIA Graphic Cards. One solution that was suggested was to set the Power Managment Mode = Prefer Maximum Performance.

I have mine set that way with NVIDIA Driver V546.08 and Dell BIOS 2.15.1 and so far, I have not had any freezing issues for 24 hours.  I am going to continue the testing. 

I have two Dell XPS 8940 desktop PCs. One has the NVIDIA TX 3060 graphics card. Around early October is started randomly freezing nearly daily requiring a hard reboot. No meaningful error messages in the Windows event viewer or reliability history. Updated all the drivers, tried uninstalling various programs, and even perform a clean Windows 11 install to no avail. I began saving my work excessively never knowing when the PC would lock up.

Finally found a solution by rolling back the BIOS and NVIDIA driver and haven't had any crash in several weeks since. here is the stable combination on my machine:

Dell BIOS 2.14.0, 8/2/2023

NVIDIA 536.40 Win10 64-bit / Win11

I also uninstalled the Dell update tool so it will not try to update my BIOS automatically.

Just for the heck of it I installed the latest NVIDIA driver 546.29 today to see if it would work and my PC crashed within an hour. Went back to my previous combination and everything is fine again.

Super disappointed with Dell. I thought I would give them a shot and picked up some good deals on the XPS8940s. The overall quality isn't there and the support is useless. It will be back to custom configuring my next PC with iBUYPOWER.

I bought my XPS 8940 i7-11700 in 2021. Don't ever remember it freezing until recently. I ran Linux Mint for the first year then switched to Windows 11. Only in the last month has the freezing started. I have a low-end Nvidia GTX 1650 installed. I switched back to Linux Mint to test and it has frozen everyday since. I've tried the latest BIOS all the way back to 2.2 BIOS from 2021 - no change still freezes. Tried newer Nvidia drivers and rolled back - no difference. 

Going to test opensource Nvidia driver on Linux Mint to see if it makes any difference next. After that I'll remove the Nvidia card if it still freezes to test that theory. It's just odd that it worked for 2 years with no issues and now daily freezing under Windows or Linux. 

@kstar42​ 

Sort of confusing to me?

If I understand it correctly, you were running Linux, and about a month ago went to Windows 11? The freezing started, and then continued when you switched back to Linux?

So I have a few questions for clarity:

• About how long ago did you switch to Windows? 2 years ago?
• What did you change about a month ago?
• What BIOS version were you one and was V2.16.0 installed before it started to freeze?
• How did you Re-Install Windows, back-up or a fresh install?
• What Nvidia driver versions did you have before and now have?
• Do you have GeForce Experience and Nvidia Control Panel installed?
• When installing the 'new' Nvidia driver, do you do a CLEAN INSTALL?
• Have you kept up with ALL Dell Updates?
• Have you kept up with ALL MS Updates?

I do have some suggestions to try as well:

First thing, clear out ALL remnants of any Nvidia installed files and data. To do that, go to https://www.guru3d.com/download/display-driver-uninstaller-download/ and get DDU. Follow the instructions. You WILL need to connect your Monitor possibly to the Intel HD750, but it really isn't necessary. However, PRIOR to do this, get the latest Nvidia Driver from Nvidia's site, and you will/must disconnect from the Internet prior to running DDU and rebooting into Windows Real Mode which is where you'll need the Nvidia driver to install.

Now, a lot of people have had some success altering DEFAULT Nvidia Control Panel settings. See this link for details: https://windowsreport.com/nvidia-driver-keeps-crashing-windows-11/ and specifically section #4 Reconfigure settings in Nvidia Control Panel.

I am on Ver. 2.13.0 of the BIOS, all after it seems to have caused problems. Don't know what BIOS you are on now, but I'd suggest installing that before doing anything else.

Hope this helps.

@ispalten​ I had linux installed from the beginning when I purchased in 2021. That ran for about a year or so then I switched to a Windows 11 install for the next year or so. Never froze until recently (around November 2023.) I checked to see if there was an updated BIOS as an attempt to fix the issue and did the December 2023 BIOS update. NVidia did update in the last quarter. Yes clean installs each time. Yes GeForce Experience and Nvidia Control Panel. 

I have Linux Mint installed on disk0 NVME and Windows 11 on disk1 SATA SSD. - dual boot system now. Like I said I've tried using older BIOS's to see if it would make a difference but it did not. So Windows updates, Nvidia updates, Dell updates to me are not the issue - Linux used to run fine and so did Windows. 

Just providing info. 

I have the same issue with XPS8940 with RTX2060 since sometime in Octber 2023. BIOS 2.16.0 Tried everything including rebuilt Windows 11. I finally pinned down the problem lately after I set the BIOS to use Intel UHD graphics instead of Auto (this will set to RTX2060).  I have not had any freeze since.  So the issue is with the RTX2060.  I will now tried to find out how far back do I need to setback the NVidia Driver. Stay tuned.

Well, I don't know why you were not experiencing problems until recently, but I've had problems since the Release of BIOS V2.4.0. Varying degrees of time between lock-ups on different BIOS version. I too have an RTX2060 6GB Dell supplied card on an SE8940.
I have had varying luck controlling the problem, with a variety of proposed changes from CPU BIOS settings to a variety of both Dell and Nvidia drivers (both Game Ready and Studio) with no reliable results.
As for your changing the BIOS to the HD750, number one, these are the BIOS choices:

I have it set to Mult-Display.

As I understand this, and I could be wrong, IF your HD750 should fail, and the Primary Display is NOT set to AUTO, and you select the Intel HD750, you will not see anything on boot, at least for the DELL/BIOS screen.

My Primary Display Setting:

I don't know why this solved it for you? It is quite possible you are NOT using the RTX2060 at all. All users have tried using only the HD750 and never seen a fail, so that is what I suspect you are doing, only using the Intel adapter.

Right now, I'm on BIOS V2.13.1. I also made the Nvidia Control Panel changes to Sync and Max. Power. I use the lastest Nvidia released Game Ready Drivers installed using the CLEAN option via GeForce. I did use DDU to CLEAN OUT all Nvidia components a few months ago as well.

All I can say is it works for me.

Not sure what your use of the PC is, but you might want to check what IS the actual Video adapter you are using? Even if the cable to the monitor is connected to the RTX2060 it doesn't mean it is in use. I discovered that by accident when I decided to DISABLE the card in Device Manager and DID not change the cable to the HD750. It seems it sits on the same bus as the Intel adapter and uses its signal if the card itself is not selected/enabled.

@ispalten​ 

You are right, When I select the Intel HUD, I am not using RTX2060. I have to switch the video out cable from RTX2060 to the motherboard video out. That is why I said RTX2060 is the source of problem since I have the latest BIOS build. Now I have to figure out which driver of NVidia is the problem.

No, the problem is NOT the Nvidia Driver, or at least not the whole problem. The DELL BIOS is the problem, or the main cause.

What I did was used from GURU3DD.COM DDU to clean out all the Nvidia parts running under Safe Mode with the Internet disconnected. Before doing that, get the latest Nvidia driver from NVIDIA.COM. Also get from DELL BIOS V2.13.1. Before switching over the Safe Mode, install the BIOS, and then switch to Safe Mode. Run DDU (make sure the Internet is NOT connected before doing this too). After DDU is completed, now boot into Real Mode. Again, leave the Internet connection off (if WIRELESS, disable the Wireless Adapter, probably your Killer Wireless card). Now install the Nvidia Driver. After that installs, reconnect the Internet.

Lastly, in the Nvidia Control Panel, make the changed in #4. Reconfigure settings in Nvidia Control Panel on this web page, https://windowsreport.com/nvidia-driver-keeps-crashing-windows-11/ and almost all that have done it have cured the problem.

I have not tested ANY BIOS since V2.13.1, but later ones might work?

Give it a try. Doesn't work, you can go back to the HD750.

@ispalten​ 

Thanks, I'll give it a try. But after reading the Task Manager. It occured to me that my setting on BIOS is to have Intel HUD as the primary, and NVidia as the secondary, both are being used while playing or rendering videos. For some reason, setting the Intel HUD as primary fixed the problem. I can use either the MB's HDMI output or the RTX2060 output.  The usage will be different due to the display processing.
