I have an ASUS Sabetooth z97 Mark2, updated to the latest bios and when I install Windows 10 the first thing I notice is it is using the default microsoft video driver. I have an ATI FireGL v7350. I downloaded the latest driver and installed it, but it does not get picked up. I have updated the chipsets with the latest drivers and still no luck. I have four other computers that are a lot older and didnt have a problem one installing Win10. This box which has the z97/ati video/32g of ram/SSD. just will not upgrade properly. I am out of ideas, any help would be appreciated.
