I've assembled an M8 Barebone Gaming PC and then, as the first software, installed Windows 8.1 64bit. The system is up and running but I've noted that the Card Reader (cannot read an SD Card) and Internal Audio (headset connected to PC is mute) is not working. I'm assuming then that the Microsoft Windows Drivers doesn't support all the motherboard functions / chip. On the ASRock web site I can see a list of Drivers and Utilities and, while it is not very easy to understand whether the Microsoft Drivers are more recent tan the ASRock ones, I ASK YOU if it is a "safe" policy" to INSTALL ALL the software proposed by ASRock for Windows 8.1 systems (like mine). Thanks.
