It stops at 0% for quite a while, then it gives in ..

Could this be the reason, if so how do i stop it ..

You might need to uninstall and reinstall SupportAssist and/or Dell Update. Manually set a System Restore point first, to be safe...

Many thanks for your quick response.

I have uninstalled and reinstalled three times, also I have made sure that windows 10 was fully updated.

Its only gone wrong for some reason in the past few days, in that time I have installed DropBox, but I shouldnt think thats anything to do with it, what do you think ??

Sometimes, but not always I get the message ...

A task is currently in progress. Wait for the previous task to finish.

Then it gives up on hardware scan.

Can we assume you reboot the PC after you see that error?

Did you install the dropbox app?  Is it set to load and run in background after every boot? In that case, have you tried disabling it and then running SupportAssist?

You could try doing a System Restore using last restore point available before you installed dropbox. Then see if SupportAssist works again, without dropbox being installed.

How are you uninstalling SupportAssist? Sometimes things get left over when SupportAssist is uninstalled that messes up the reinstall. If a System Restore doesn't get SupportAssist working, try using Revo Uninstaller (free) to uninstall System Restore. Then reboot and install it again.

thank you Ron for your reply. 

still no progress I’m afraid. I’ve tried running it with and without Dropbox installed, it didn’t make any difference. 

also I have uninstalled and installed Dell SupportAssist, with rebooting, still having no effect on failed hardware scan each time. 

im still scratching my head, it was working a week ago, so why not now.

Follow this Guide from start to end, I have had countless remote sessions with TECH support and this is what they do to fix the issue, 

Follow this Guide from start to end do not miss any steps 

You may find that a few thing I am recommending to delete are already deleted from your computer so skip those steps.  

1 Use Microsoft's Installer : 

This step is crucial as Microsoft's uninstaller disables the services as well. Choose SupportAssist and uninstall, Uninstall Dell updates by running the the uninstaller again. If Support Assist doesn't show in List ignore this step. 

Reboot (important) 

2. Delete following folders and ignore the once which are already deleted. 

C:/ Program Data/ PCDR 

C:/ Program Data/Supportassist 

C:/ Program Data/Dell/Dell data volt 

C:/ Program Files/ Dell/Supportassist 

C:/ Program Files/ Dell/ Dell data Volt 

C:/ windows/Temp (everything inside the folder 

Remove these Registries 

Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services key.

Delete Dell hardware service, Delete Dell client management service, Delete Dell updates. 

Open device manager > system devices : If you see 2 Dell dala volt devices, please uninstall the second one. 

Reboot 

install SupportAssist 

I have tried doing it via the support page and the check for drivers update gets stuck on 90%. Is very disappointing that this is happening with a 6 months laptop. For some reason, I feel the fans are running higher than usual so was thinking an update may fix some bug from a previous bios update.
