D7 mmm. 

there are diagnostic light 

red for cpu

yellow for ram

white for gpu

green for boot disk keyboard bios. 

I will recomend also to flash the bios .  Check here if the pc is brand you what are the last 4 numbers.  There is sticker here  the minimun bios is 0505

Let see what can be done from here 

I remember also a update of bios (flahs) where the usb was done incorrect also push D7 error

Hi @danielclark 

Update the UEFI to 1804 using USB Flashback method

If no change:

Please try a simple wired USB keyboard directly in a rear USB 2.0 port (no hubs, no monitor pass-through, avoid the USB-C / 3.2 ports), then power-cycle and test again.

If no change: try with 1 DRAM module in A2, GPU, and boot drive

Thanks for reply mate. So I have detached all usb’s and still same error. Tried removing Monitor and came up a d6 error. Put screen back in, and unplugged from B2 then got 99 error again.
