Way MSI not support oficial K9A2 Platinum for Windows 8 and RX3850-T2D1G This Windows work perfect on my PC but not official driver support only for Vista and 7 but this is old and not better. I ask MSI on forum don't answer me way not support Windows 8 but support Windows 98SE and 2000 - this is retarded
Your MB & GPU are just older. MSI does not support that MB & GPU any longer so there are no new drivers for the newer OS's that are coming out. MSI says that the MB does not support Win 98 or ME either. See this link:
The chipset driver is listed as Win 8 supported. But the other drivers are only listed for Visa or Win 7.
