I suggest you take one and Nuke-and-Pave a clean Windows install onto it. [URL]#M3401 Looks long, but it's easy. Read thru it once before you start. Verify you got the latest BIOS and it passes ePSA Diagnostics (outside of Windows). Connected to a good UPS-Battery (like APC) is best. Set BIOS to UEFI/AHCI (SAY NO to RAID) . No Intel-RST loaded ever. No SupportAssist. No Dell software or extra Processes and Services. No heavy driver-suites (keep it lean). Media Creation Tool for Windows 64bit from Microsoft.com . Do First-Time-Setup. Just Microsoft drivers (from local Windows-cache or Windows-Update). After it's working, drop by nvidia.com and get that WHQL studio driver (DCH). I bet that will work. Takes about 60 minutes, start to finish.
I purchased 3 XPS 8940 PC's.  All 3 of them blue screen intermittently straight out of the box with no changes to the factory image. If you take a look at the dump files they all indicate a driver issue with the video card: VIDEO_TDR_FAILURE There is no pattern for when they crash. One crashed overnight with no one using it. All 3 systems have a NVIDIA GeForce RTX 3060 video card. Used Dell Support Assist to make sure all 3 systems have the latest BIOS and drivers for all components. I also went to NVIDIA's site and tried using the latest Studio Driver for the card which was different than the pre-loaded driver and they still crash with the same error. Computers are used for kitchen design and not gaming. Called DELL basic support (India) and they ran a Hardware Diagnostic which passed with no errors. With that they told me nothing was wrong with the PC and have a nice day. Tried to get Basic support to escalate the situation with no luck. Called my sales rep at DELL and their solution was for me to purchase a Pro Support Plan that would get me "Advanced Support Assistance". Really? Sales Rep also says if I call into basic support more than 3 times about the issue they would probably send me a new PC. Why would I want more PC's with the same issue? What poor Customer Service. Not sure what to do next. Anyone run into this problem or something similar? DELL if you are monitoring this board can you please get me in touch with someone who can analyze the dump file and figure out what going on with these PC's. I have $9000 dollars invested and they only have been deployed for a week.
