The system is a HP N40L which is a Microserver running an AMD CPU. In this I have placed a nVidia GT620. Whenever the onboard NIC Is enabled (via BIOS) the system either throws a Watchdog Violation or simply sits at the Win8 loading screen (where the little circle goes round and round) and never loads. As per DPC_WATCHDOG_VOILATION after install windows 8 - Microsoft Community and dpc_watchdog_violation during windows 8 upgrade - Microsoft Community others are having this problem as well, however we all appear to have the latest NIC drivers (Windows 8 x64 188.8.131.52 10/29/12). Attached is the information i have gathered from that system View attachment N40L.zip Thanks in advance!
