I have a DG31PR motherboard and the Mass storage controller driver is missing on device manager. It has a ! next to the mass storage controller. Do you have a link to download this driver? I have Windows 7 Ultimate Greek 64-bit.
Hello Marios14, thanks a lot for posting your inquire at Intel communities.
Regarding your situation, please make sure you have all necessary driver installed on your system such as Chipset driver, graphics, Management engine, USB, LAN and audio.
If you continue having this behavior, please check if there is any other device connected to the board than needs some drivers.
