PC freezes after about 5 minutes. Recently upgraded build

PC Specs:
Motherboard: Asus Z97-AR
Processor: Intel Core i7-4790k 4.0Ghz
Power Supply: Corsair CX600M
Video Card: MSI GeForce GTX 970 4GB
Cooling: Corsair H100i GTX
Memory: Corsair Vengeance Pro Series 16GB (2X8GB) 2400Mhz and Kingston HyperX 8GB (2x4GB) 1600Mhz

I added the new motherboard, processor, and liquid cooling yesterday. I ignored the CPU fan in the BIOS to accommodate the liquid cooling and lowered the DRAM frequency to 1333Mhz in the BIOS as well. Last night, I was able to use my PC for hours with freezing in one session. Previous sessions before that would freeze. This morning, the same settings I had began to freeze my PC as well. I believe the main problem may be that the motherboard is forcing overclocking or the memory may be incompatible, even though it recognizes the 24GB. Can anyone help?

if you remove the Kingston hyperX 8GB ram, see if it freezes again.

It mostly freezes when I start a game up. I tried removing the 16GB first and starting up a game but it still crashed. I'll try the 8GB right now. Thank you

Removed the 8GB and it still froze when I opened a game.

Check if you haven't bent any pin in the motherboard socket and see if you have got any thermal paste in it too.

No thermal paste leaked and I disconnected and reconnected everything but nothing

Have you tried taking the build out of the case and breadboard it?
Make sure the motherboard isn't touching the case and isn't shorting.
