Because MSI didn't set a buzzer for this motherboard, if the problem is due to RAM, you won't ever know. So if you can, get a buzzer and install it on your motherboard is the best way to solve this problem. But before it, you still can do something to test other components.
Pulling the CPU fan from the motherboard, then Power on and touch the surface by your finger and to see whether CPU will hot (Be careful! You must power off the system in 'very short time', if not, your CPU maybe burn out!). If yes, congratulation! Your CPU work normally.
