Optiplex 3030 BSOD on Windows 7 Boot

We have several 3030 AIO desktop computers running Windows 7 on our campus.  Any of these machines imaged with Windows Deployment Services will BSOD at boot.  The error is:

stop 0x0000007E (0xFFFFFFFF80000003, 0xFFFFF8800536F02D, 0xFFFFF88003FD8EC8, 0XFFFFF88003FD8720)

We have another server (2012r2 upgrade) that deploys Windows 7 to these AIO desktops without issue, so we know it's not our image.  It would seem the drivers are OK too, since the other server doesn't have the same issue.  That said, we can deploy images to any other Dell computer, desktop or laptop, without BSOD and Windows 10 works fine.

So far we have tried:

the driver .cab files from 2014, 2015, and the most recent 

Server 2012 R2 and 2016 (completely fresh install)

Dell's diagnostic utility (Pre-boot System Assessment)

Resetting BIOS to default

We've hit a dead end and I'm hoping someone can recommend something new to try.

Thanks in advance!
