Fails SupportAssist, PCI SubSystem failure?

@DELL-Cares, per this thread, what about PCI SubSystem failure? Would this be the same?

My keyboard was replaced recently, after that I had the feeling that the fans of my inspiron 14 were running louder than usual and now right before the fans start, it makes one little clicking sound. I checkted the devide manager and there was an error under "DellInstrumentation Device". There was two with the same name, only one had the error. I clicked uninstall then checked for updates and tried to find a driver for DellInstrumentation online but didnt succeed. yesterday the system froze twice, which never happened before. I had to restart it with the power button. 

Its a new laptop I only had it for about 3 months! :(

Hi @Nani04 :

While you're waiting for a response from DELL-Cares, please let us know your Dell computer model, your Windows OS (including the version and OS build shown at Settings | System | About | Windows Specifications) and whether your Dell service warranty has expired yet.

Do you have the latest BIOS recommended on the Dell support page for your computer model?  To find your current BIOS version open a Run dialog box (Windows key + R), enter msinfo32 to view your System Information, and look for the field named "BIOS Version/Date".

Is your Windows Reliability Monitor logging any errors or warnings?  If you run an advanced F12 ePSA (enhanced Pre-boot System Assessment) hardware diagnostic from your BIOS as instructed in the Dell support article How to Run a Preboot Diagnostic Test on a Dell Computer (also see the companion video at does it detect a hardware problem and generate an error code?

I don't know the purpose of the DellInstrumentation Device but some of the following information might be helpful for your troubleshooting.

I found one topic in the reddit Dell subforum at Unknown Device "DELLINSTRUMENTATION" after Win 11 upgrade that suggests that the Dell Instrumentation service (which might be listed on the Processes tab of Task Manager or at Start | Windows Administrative Tools | Services on your system) could have something to do with the temperature sensors and fans on the motherboard.  However, that doesn't seem to be the case on my Inspiron 5584 / Win 10 Pro machine.

If I open the Device Manager on my Inspiron 5584 / Win 10 Pro laptop I only see one entry for the DellInstrumentation Device (driver version, driver date 14-Apr-2022), and if I double-click to open the Properties, choose the Events tab and click the View All Events button ...

... this launches the Event Viewer and creates a new custom view called "Device Manager - DellInstrumentation Device" that displays all events in Applications and Service Logs | Microsoft | Windows | Kernel-PnP | Device Configuration that are related to the DellInstrumention Device.

All six events logged in the Event Viewer for my DellInstrumentation Device have a level of "Information" (i.e., no errors or warnings) and only occurred on two dates, 02-Dec-2022 and 08-Feb-2023,.  According to my notes these dates happen to correspond to the date I updated to Dell SupportAssist OS Recovery Tools v5.5.5.16206 (on 02-Dec-2022) and the date my Dell SupportAssist OS Recovery Plugin for Dell Update was automatically rolled back from v5.5.5.16206 to (on 08-Dec-2023).  I don't know if that's relevant or just a coincidence, but see the 22-Mar-2023 post in my thread Dell SupportAssist OS Recovery Plugin for Dell Update Rolled Back to v5.5.4.16189 that explains why I decided to uninstall all SupportAssist-related software (including Dell SupportAssist OS Recovery, also known as Dell SupportAssist Remediation) from my Inspiron 5584.

I now use Dell Update for Windows Universal v5.x to check for available Dell software and drivers, Dell's F12 ePSA (enhanced Pre-boot System Assessment) built in to my Dell BIOS whenever I need to run a hardware diagnostic, and Macrium Reflect Free imaging software to create the occasional full disk image of my hard drive in case I ever have to perform an emergency recovery.
