m17 R2, missing drivers

Question

Hello Community, Recently did a factory reset on my Alienware m17 R2 laptop. Previous version of Windows 10 Pro was 20H2 I do believe (worked just fine & all drivers installed with no problem) but after the reset it installed version 21H1 which I've been trying to avoid like the plague! Downloaded windows updates as usual and used Dell Support to download most 'urgent' drivers that Windows Update won't keep up to date. Also used the Alienware Update program which only found a Nvidia graphics driver with the same version as Dell Support which was released in Sept.2021. Side note, GeForce Experience had an even newer version released on Nov.16th,2021 so of course I installed that version. So with all these drivers downloaded, I check Device Manager and in the 'Other Devices' section, I have the following drivers not installed...even after right-clicking each one and attempting to Update Driver. I've included the hardware I.D. numbers, so I'm asking for help with a possible link to where I can find these.  -PCI Data Acquisition and Signal Processing Controller (A379) -PCI Device (A324) -PCI Serial Port (A373) -SM Bus Controller (A323) I do apologize for the long post, but just wanted to give you an idea of most of the steps I've taken. Far from an expert but I can get my way around most pc problems I come across...just not this one. Thank you all for your time and assistance in regards to this matter!

I decided to put a fresh install of Windows 10 Pro (1904 build). All driver issues resolved problem solved.

Update: I've tried many online solutions I read about as well. Couldn't find anything on Microsoft Update Catalog using the Hardware/Vender I.D. numbers either. I need help with this! Thank you
