Hardware Drivers :: Can 8.0 Chipset Drivers Be Used For Windows 8.1?

I'm having a problem with system file corruption on two computers with ASUS Sabertooth 990FX Rev 2 motherboards and some resulting issues after upgrading from Windows 8.0 to 8.1. ASUS still doesn't have 8.1 chipset drivers available for their AMD motherboards but they have 8.1 for their Intel boards, which is interesting. I have been told by a third level MS Support person that the corruption is caused by a hardware issue and he refuses to troubleshoot the computer until the corruption is resolved. He said that in the 8.0 to 8.1 upgrade, Microsoft made some significant changes so he thinks that 8.1 chipset drivers should be installed.

Every few days, when I run sfc /scannow, it finds corruption. If sfc can't fix it, then I run the dism /online /cleanup-image /restorehealth command and eventually it gets fixed. In the meantime, some strange things happen with Window's operation but I don't get BSODs and other major things but the computer can hang for a while.

I have contacted ASUS but I get conflicting information from them. I see that here: ASUS Windows 8.1 - Ready Motherboard : Get you Onboard, that many AMD boards have passed the WHQL test (only very recently--the Intel boards had already passed some time ago) but when you click on any link to an AMD board, there are no 8.1 drivers available, even where it says they have some. I have been told by ASUS's Customer Care Manager that AMD provides the chipset drivers. I have spoken to AMD Support and they say that they do NOT provide motherboard drivers--the motherboard manufacturer does. I then told the ASUS Customer Care Manager this--then he said:

"ASUS would have to work with AMD in the development of such drivers, and since our testing of Windows 8.1 with the current 8 drivers has worked without further issues there is no word of further development of a Windows 8.1 chipset driver set for that motherboard. It isn't deemed necessary as of now. This is also due to the fact that AMD is working with ASUS to develop other products with their FM2+ socket and APU processors such as the board in the link [URL] .....

As far as the appropriate chipset driver for the Crosshair V Formula-Z, it is already available but it the same driver that is used for 8, and the only driver that needs to be updated further after that should be the USB 3.0 driver. The webpage you described is just dated and isn't meant to be used for continued reference. Our product page just hasn't been updated to reflect the information I am providing."

I wonder how much in depth testing ASUS did with the AMD boards which supposedly work fine running Windows 8.1 on a motherboard using 8.0 chipset drivers?
