Hi @Foxelion 
If you were having some issues with DRAM module detection I would recommend reseating the CPU, especially if you've moved house.
DIMM detection issues can often be a CPU pin pad contact issue.

Hello Foxelion

To add to Silent_Scone's suggestion.....

Code A2 and d7 with no display could be pointing to something with the gpu.

When moving or cleaning your pc, maybe some cables got bumped.

Check the pcie power cables to your gpu are firmly in place.

Check your monitor cable is fully inserted at both ends.

Check your monitor is in stand-by mode or press the power button to turn it on.

If nothing is helping, try reseating your gpu in the pcie slot.

If all else fails, try clearing the cmos, if no help, reflash the bios.

Hello, @Foxelion 

May I ask what the current model of motherboard you are using is?
We recommend referring to the installation instructions in the motherboard user manual to ensure all hardware connections are correct.
Additionally, the Q-Code table at the end of the manual can provide further reference.
Meanwhile, please refer to [Motherboard] Troubleshooting - No Power/No Boot/No Display and test with minimal components to isolate the possible cause.

Thank you.
