Update I am running a Dell XPS 8930 Special Edition, purchased in October 2019, with Windows 10 Pro, x64, Build 1909, fully updated, including February Windows 10 updates.  I was intrigued by boheap's reply, in this topic here because I also run Malwarebytes Premium 4.04 (fully updated).  Malwarebytes was not throwing any errors when I tried to run Scan Hardware with SupportAssist 3.4.1.49, nor was the SupportAssist program itself. Rather than disable my Malwarebytes Premium (MBP), I decided to add the following folders to the MBP "Allow List" before testing whether disabling MBP had any effect.  I "allowed" the following folders to be exempt from any MBP protection: C:\Program Files\Dell\SARemediationC:\Program Files\Dell\SupportAssistAgent I rebooted my computer, and now Scan Hardware works just fine and passed.  Also, under Troubleshoot, I can now see my hardware components, whereas before no hardware components would show even after I clicked on "Refresh". I will be posting my experience on the Malwarebytes Forums in the Malwarebytes for Windows Support Forum later.  I hope that Dell and Malwarebytes will get together and address this issue, since users have no way of knowing that Malwarebytes is preventing certain components of Dell SupportAssist from working properly, since no errors and "blocking" is reported by MBP.  I will be posting there under my usual user name "garioch7". I hope that this helps someone else, and I extend my gratitude to boheap for his reply which got me motivated to do some testing with MBP. Have a great day. Regards,-Phil
I have tried scanning hardware several times today, rebooted, and also did a cold power start.  The scan starts and jumps to 100% almost immediately.  I have run this scan before many times, and it does take about 10 minutes, as stated.  The History shows this: "Hardware Scan Result (Manual) - Default scan - Test Not Started - February 1, 2020 1:51:30 PM" .  SupportAssist itself is showing no errors: it just goes to completion in a few seconds and states "Passed". I wanted to run this scan because my monitor suddenly blanked out, complaining of no signal.  I did a cold-power start and reseated all of the cables (none were loose), and the problem went away, at least for now. The computer is a new Dell (October 2019) XPS 8930 Special Edition, running Windows 10 Pro x64, Build 1909, fully updated as of yesterday. Any suggestions appreciated.  Have a great day.

SupportAssist will not scan hardware
