Problems SInce I installed new ram

[InTroOfficial]

Hello there I installed my new RAM about 3 days ago ( I upgraded from 8gb to 16gb 0and since then my computer has been getting blue screens with error messages like 'driver overran stack buffer' or ‘Kernel Security Check Failure’ and my games have been crashing etc.
I googled the ' Driver Overran stack buffer' and it told me to run a security check ( I used windows Defender ) but that showed me an error message 'Kernel Security Check Failure'

And I don't have a clue how to fix this please help any advice will be welcome.

Here are my PC Specs if needed
CPU: Intel I7 4790k (not overclocked)
Ram : 16gb of Corsair Vengeance pro @ 2400mhz
GPU: Gigabyte 970 WIndforce edition
Motherboard: MSI Z87-G45
PSU: Cooler Master G650M
SSD: Samsung Evo 128GB
HHD WD Black 1TB
CPU Cooler: COrsair H75

does it work fine if you removed your new ram?

Is it 2x8GB, 4x4GB or 2x4GB with an 8GB stick? Regardless mixing sticks offers no guarantees they will play nice, let me know the model numbers and we can try some adjustments to the DRAM settings
