Optiplex 7040 NIC disables in BIOS
I've got an OptiPlex 7040 that sporadically shuts down without a BSOD and when it is powered back on, the NIC is disabled in BIOS. We have to reboot and re-enable it. When the issue started happening, after enabling it, even a normal reboot would disable the NIC again.
I updated the BIOS and other drivers, didn't spot anything in the event log... opened a ticket w/ Dell support and they eventually replaced the motherboard.
Issue still happens, just not as frequent. Anybody else see this issue related to NIC repeatedly becoming disabled in BIOS?

I am not sure what the culprit is, but the same issue was seen here by Optiplex 5040 users and here by Optiplex 3040 users. Setting a BIOS password helped.

Great, just tried it. I'll update in a few days with results.

I've had the exact same issue on three of my 11 7040's in the last three months. I originally suspected foul play / sabotage but have discovered otherwise. I've set BIOS passwords on the three machines that did it and haven't had the problem since. I haven't tried a BIOS update though...
