I newly own an ASUS Z170-A Mainboard and the Intel Network Driver for the I219-V Adapter causes the Machine to crash regularly.
By uninstalling the Driver, the Computer runs stable over 2 Days.
With the driver installed, the crashes occur latest after about 2 Hours.
The rest of the components are:
Intel Core i7-6700 CPU
Samsung SSD 840 Pro (250GB)
Crucial 16GB 2 DIMM Kit (CL15)
Corsair 650 W Power Supply
Seagate ST3000DM002-1BJ166 3 TB HDD
For now, the system is of no use for me, since it's only stable when offline.
And searching the net, I am by far not the only one having this problem.
Please update driver soon.
