Make sure it is fully seated. Try different slots if there are.

Check if the memory is supported by the motherboard/bios.
You might have to update the bios if it continues to not post.

Really thin on the details. Are you replacing both modules with a single 4 GB DIMM? Did you try the 4GB DIMM in both slots (or all four if it has that many)?

Yup. A Dell Core i5 2nd gen in office needed the 4GB DIMM to be taken out and installed again in a different slot after every shutdown. After almost eight (!) BIOS updates, it has worked flawlessly ever since.
