The problem that you are having could be related to a lack of power from the power supply. The fact that it only occurs when all modules are installed, might be due to the fact that your power supply is not able to power all the hardware on the system.
Another alternative would be a compatibility conflict with the RAM. Bear in mind this processor does not support RAM voltages higher than 1.5V. Please confirm that your memory does not require 1.6V or more to work.
Dear Jose ,
I use 450 W power supply and he memory is on 1.5V
To troubleshoot the problem, I would still recommend testing a larger power supply. Please let us know of outcome.
