XPS 8950, integrated video card failure error

XPS 8950

For the last 3 months, I have experienced monitor flickering and black screens lasting several seconds on the desktop. Support Assist app and troubleshooting individual component test for the video card fails. Dell support has replaced the motherboard 4x and the cpu once. The unit was also  sent to Texas for repair and only the motherboard was replaced. New motherboard replaced yesterday has the same error and now will not activate windows 11 and I continue to have the video card failure error, with same symptoms on the monitor. Has anyone experience this issue or have any idea what's happening. I am unable to use the system reliable. The desktop was purchased in Jan 2022 and seems to begin the failures at 6 months. Dell service is scheduled to replace the motherboard again this week.

So no add-in video card? Some recent drivers for add-in NVidia cards have been causing black screens. So you might try an older driver.

How much RAM in this system?

Does the monitor flicker on another PC?

What port are you using on monitor, DP or HDMI?

If HDMI, what kind of adapter do you have? Have you tried a different video cable?

Hello;

No NVidia drivers installed; updated Intel drivers, used older drivers, tried drivers direct from Intel site, no change

How much RAM in this system?

Does the monitor flicker on another PC?

No monitor does not flicker with another PC

What port are you using on monitor, DP or HDMI?

The 8950 I have only has a DP port. I am using a Dell 2721DGF monitor. Using the 8950 with an older monitor with a DP to HDMI converter cable gives same video card failure on testing. 

If HDMI, what kind of adapter do you have? Have you tried a different video cable?

I  only have the Dell supplied DP to DP cable. The DP to HDMI cable I have does not work with the monitor.

So you're using DP(PC)>DP(Monitor), correct?

Does the flickering occur when you're doing something specific, eg, waking from sleep or using a browser?

Look at the (Advanced) Display settings in Win 11 and if there's a hardware acceleration option, disable it. And do same in whichever browser(s) you use.

You can also try this:

  1. At desktop, open a CMD prompt window, Run as administrator

  2. At the prompt, type in: chkdsk c: /r and press Enter. Accept offer to run chkdsk at next boot and reboot PC. chkdsk will run before Windows loads so be patient. See this to read the chkdsk log when you're back at desktop.

  3. Open CMD prompt window again as in #1

  4. At the prompt, type in: DISM.exe /Online /Cleanup-image /Restorehealth and press Enter. Be sure to include a space in front of each / and note any error messages when that's done.

  5. Assuming no "unfixed" errors in #4, at the CMD prompt, type in: sfc /scannow and press Enter. Be sure to include a space in front of the / and note any errors when that's done.

  6. Assuming no "unfixed" errors in #2, #4 or #5, reboot PC and see if problem continues

Have you logged into your Microsoft account? That should activate Win 11. If not, you may have to contact Microsoft directly and explain the motherboard replacement and request activation that way.

Read this for a link to a DP(PC)>HDMI(Monitor) cable that works with XPS 8950.

Hello and thanks for the replies;

1/ there is no hardware acceleration toggle in windows advanced display. The problem occurs on windows desktop and in Excel and other  apps so I don't feel it's a browser issue.

2/ chkdsk, DISM, SFC ran without errors.

3/ when I logged in this morning I found that windows was activated. 

4/ I may try a new DP to DP OR DP to HDMI cable to see if that has any effect. I have another MB replacement this week so I  will determine next steps post replacement.

Hard to fathom you've already had motherboard replaced 4 times and awaiting #5. That would seem to suggest the problem is elsewhere, like the video cable.

Since onboard Intel Graphics uses system RAM, that's another possible cause, and/or heat issues if a fan(s) isn't working properly.

Post back and let us know what happens after the new motherboard and/or new video cable.

I wasn't going to post because after 4 motherboard, I could not image how an on-board Intel GPU could still be broken.

But I bet this is why. When you get a new motherboard, they usually just move the RAM DIMMs over. So, I suppose the ram or even the main Intel processor are suspect about now.

I have this problem with my 8940 (screen going blank periodically and severe crackle in the audio [no video card, 32GB mem etc.]). I tried replacing the RAM and got no improvement.

It was really bad with HDMI and slightly less bad with DP. I tried buying expensive cables for both with no improvement. What I am doing now is turning the monitor off physically before I boot the system and then powering the monitor on. Doing this I get blank screens very rarely (still happens though). I'm assuming there is some kind of sync problem that arises from some edge condition in the system from problems distributed across the 8940 video system, video cable and monitor. I've tested the monitor with one other computer and I've tested the 8940 with one different monitor, using the same cable in each cases. There were no problems in either alternative configuration. My current Acer monitor is the only one that fits in my desk space so I do not have the option of permanently replacing the monitor with a different model. Basically SOL.

If either of you have a working add-in PCI-e x16 video card, either a spare card or one you can borrow from another PC, try installing that card and see if it solves the problem.

Doesn't have to  be an expensive/fancy card. You just want to test video output when the monitor is connected directly to the add-in card, instead of to onboard Intel Graphics.

And there's the "when all else fails" option of trying a clean reinstall of Windows.  Be sure to image your boot drive first. Macrium Reflect (free) is a good tool for this.

After the clean install and full update via Windows Update, install only one or two key apps and see what happens. If it doesn't blank the screen, continue installing your apps until either everything is installed without problems or you find the culprit.

If the clean install fails after only one or a few apps are installed, you can re-image the boot drive back to the way it was, so you don't have to reinstall all your apps again.

So after the last MB change, change of rm and cpu, the prepost test of the video card ran fine, however, the troubleshooting test in Support Assist fail the video card test. In fact the test did not complete. So I again removed all display drivers and had windows reinstall. I received the same result with the test. Purchased a Monoprice Dp to DP 1.4 cable and rested. I got the same result again.. The only hopeful aspect is that so far there has been no screen flicker and no black screen events. Someone on the internet, said not to worry about the support Assist tests as long as the prepost tests pass, as windows may be interfering with the results. I'm not sure if I posted the video card errors from SA history; here they are.
