I started receiving the same error message after running SupportAssist on 04/17/25.

@RetPC​ 

That's exactly what happened to me.  I attempted to open the BIOS to run the troubleshooter but unable with my wireless keyboard.  I tried the F12 while starting as well as the Fn but it won't boot into BIOS.  Wonder if this is happening to everyone as well.

i had and still have the same issue...   you guys get blue screen stop codes too?   they've replaced my motherboard three times i think it was...   

@SUB666​ Yes, I have all the same issues with my desk top.  Blue screen errors and when running support assist get these errors on a consistant basis.  Dell support has no resultion for this

Go to system management

Click down arrow next to dellinstrumentation

Uninstall the outdated driver - It will be the one with an older install date. It will also have next to it a yellow triangle with a "!" in the middle of it. Right-click it and click uninstall. 

This helped fix the problem on my Dell XPS13 9210 laptop

Hey this problem not solved yet from Dell  Date: 20/06/2026

Just got my PC back from dell for a bad Ethernet. Now as soon as I opened up the PC from the box I ran updates and Hardware scan, Behold also have same problem. They fixed one problem only to give me another. They will be fixing this one. This pc been to Dell a few times. I bought 11 Alienware PC's and this is the worse one so far.

Here is 2nd picture.

Hi ribbit69er1:

What is your Alienware computer model, Windows version and OS build number [open a Run dialog box (Windows key + R) and enter winver], and current BIOS version (open a Run dialog box, enter msinfo32 to open your System Information, and look for the field named "BIOS Version / Date" in the summary).

Regarding your first image of the WD-xx warnings for your PCI bus and fan, was that hardware diagnostic generated by SupportAssist v5.5.1 or some other program/version?  If you run an ePSA (enhanced Pre-boot System Assessment) Quick Test and advanced scans for your PCIe bus and fan as instructed in my 22-Apr-2025 post <above> do any of those ePSA hardware diagnostics generate an error code?

Regarding your second image about the yellow exclamation error in Device Manager for one of your DellInstrumentation Devices, the answer <here> from Google's Gemini AI chat bot states in part that:

"The DellInstrumentation device in your Device Manager is a software-defined virtual driver used by Dell management tools like SupportAssist, Alienware Command Center, Dell Optimizer and Dell TechHub. It monitors system health hardware components such as fan speeds, temperatures, and power states, applies hardware configurations, and helps manage updates. It is not a physical computer chip."

Dell TechHub is a shared service used by SupportAssist (and possibly other apps like Alienware Command Center???) to run hardware diagnostics. Dell TechHub also comes bundled with newer Dell/Alienware Update v5.5.x apps (including Dell Command | Update, Alienware Update for Windows Universal, etc.), which seems odd to me since these smaller update utilities cannot run a hardware diagnostic.  See my 05-Apr-2025 Dell Update v5.5.0 (rel. 01-Apr-2025) Installs Unnecessary Bloat for more information.

I don't know if your DellInstrumentation Device error in Device Manager is related in any way to SupportAssist (e.g., a corrupted SA installation, a known bug in SA v5.5.1, a lack of compatibility with hardware components in your specific Alienware computer model) but you might want to read my comments about the DellInstrumentation Device in my 12-Jan-2024 post in Nani04's Fails SupportAssist, PCI SubSystem failure?. At the time I wrote that post all SupportAssist-related software had been uninstalled from my Inspiron 5584 and I was using Dell Update for Windows Universal v5.1.0 to check for available updates, but I uninstalled the bloated Dell Update for Windows Universal v5.5.0 in April 2025 and DellInstrumentation Device is no longer listed in my Device Manager.
