Product: z840 Workstation
Operating System: Microsoft Windows 10 (64-bit)

I’m receiving the attached error upon booting my z840 - i’ve had this desktop for 3 years now and have never had an issue! Recently i’ve replaced my GPU from the quadro k4000 to an rtx 2070, but don’t see how the issue is related. 

After booting it starts BIOS setup then I receive the attached, or:

520 - Memory configuration requires a memory fan and this fan is not detected. 

521 - Memory configuration requires a memory fan and this fan is not detected. 

522 - Memory configuration requires a memory fan and this fan is not detected.
