I have a brand new NUC (D54250WYK). It has 4 GB of RAM; 128 GB SSD; Intel wireless card.
I installed W7 on the machine. I down loaded and installed the driver bundle to the machine; the machine now freezes just after successfully logging on to Windows. I re-installed the OS and installed just the graphics driver. Same behavior.
Installed W8 on the machine. Same behavior.
In all cases, before I load the current graphics driver (10.18.10.3345; from the intel website), the machine is stable.
