New Windows 8 install on DZ77GA-70K board. About every 24-48 hours the 82574L integrated NIC fails hard--all communication through it stops and Windows will not shut down--the NIC seems to be hanging it. I see the same thing when looking at the NIC properties when it is hung and trying to apply any changes (e.g. IP address change)--the properties dialog hangs.
Have updated to latest drivers and latest BIOS. Problems continue. Am about to RMA the board.
