Points to a bad motherboard. If this was purchased new, then return it. There is no other reason for the system to not accept RAM in any of the other RAM slots.Pc will only boot with 1 4GB stick in DIMM4. If I try to add more sticks into any slot or add a single 8gb stick into any slot I have not boot.
Didn’t find any bent pins, I’m gonna guess that I got a bad motherboard :/Points to a bad motherboard. If this was purchased new, then return it. There is no other reason for the system to not accept RAM in any of the other RAM slots.

Edit: One other possibility is a botched BIOS update.
If I use the 8gb stick in DIMM4 I get not boot, same if I use the same 4gb stick and any slot.You said the PC boots with one 4GB module installed in DIMM4. Please confirm that you've attempted using that particular RAM module in each of the other slots. If so, what were the results? Also please confirm that you attempted the one 8GB module, by itself, in DIMM4. What was the result?
