[SOLVED] Why my PC doesn't work with new RAM ?

[TDZ2]

I had two 4 GB 2133Mghz sticks from KINGMAX but after a year one of them died and I purchased a new RAM (KINGSTON HYPERX FURY HX424C15FB3K2/16). But after installing new RAM My PC doesn't work. Coolers are spinning, led lights are working, but no signal. Here's my other parts of computer:

CPU: I7 7700K
Motherboard: MSI Z270-A PRO
RAM: OLD(KINGMAX 2133MGHZ 4GB)
RAM:NEW(KINGSTON HYPERX 2400Mghz 2x8 GB HX424C15FB3K2/16)
Graphics Card: ASUS ROG GTX 1080

Put the old ram in the machine.
Go to the mobo site and install the latest bios/chipset driver/management driver.
Reboot and make sure everything functions.
Install the new ram and test
