Usually doing so leaves the manufacturer-specific application and features alone, although sometimes you do end up having the customized manufacturer's application replaced with the OEM's specific one.
WHAT DO CHIPSET DRIVERS DO INSTALL
However, I will also download and install device drivers directly from the chip manufacturer (AMD, Intel, Nvidia, Realtek, etc.) and use those to update the OEM drivers. I will typically download and save the manufacturer's OEM drivers for hardware that I purchase throughout its lifecycle, especially if it is something that contains manufacturer-specific functionality, such as specific sound card features or co-branded applications. So - what would you do in this case? Clearly I am not going to break out the original motherboard CD that came with the product - but do you bother with OEM updates that are 3, 4 or 5 years old when rebuilding a PC or just use whatever Windows decides to use? The other side of my brain also tells me that I have read forum posts and other stuff saying that one "should" install these old timers (especially for the chipset and possible the Management Engine components). The logical side of my brain says that Microsoft must offer at least a basic driver for these components that would be newer (while stable) coming from either the OS ISO file or from Windows Update. However - if I hit the ASUS site and download the "Latest" driver as supplied by ASUS - most of them are between 3-6 years old. These old P8Z77-V PRO boards may be aged on the calendar but they run Windows 10 just fine. Now - let me preface this by saying I have a wide array of hardware here - some of it just 4 months old and other stuff dating back to 2013 (ASUS). I am in the process of rebuilding a few workstations here at home and was wondering what the consensus is between downloading (and installing ) OEM specific drivers for the motherboard vs simply letting Windows 10/Windows/Windows Update handle the drivers during install of the OS.
