Computer Hard Freezing Fault

[Keegan_Mcc]

Hi guys, so I have a big problem with my computer. I've been building computers for at least 4 years now and I've came across this puzzle ever!

Whats happening is on my home PC I've build some time ago it's started to freeze on me. Like hard freeze to where I have to turn it on/off again to resume what I was doing. This can be me just browsing the internet or me playing game. Sometimes I can even freeze right after boot.

I've ran test with Prime, some MEM tests, benchmarks and everything. I've even replaced each part(excluding the MOTHERBOARD and CPU) with the exact same parts from my brother computer and still freezes.

I though it was HDD fault and after unplugging them 1 by 1 and re-plugging them in again appears it's not. I've narrowed down my hardware to the CPU and MOBOs fault. I'm wondering if a faulty MOBO/CPU and cause my computer to freeze like this. As i've tested all the other parts separately and no fault. I've checked all the temps for everything via speecy while my PC is running and all seems to be running at stable, low temps. I've updated my MOBO BIOS to the latest and still doesn't work. Any help guys? It's been driving me crazy as I can't use my PC without running it freezing on me.
Specs:
CPU:AMD FX 9590 8 Core 4.6Ghz
MOBO: ASUS Crosshair V-Formula Z
RAM: 2x8GB(16GB)DDR3 2400Mhz Corsair Vengeance Pro
SSD:Samsung Evo 850 250GB
HDD:2x2TB WD Blue 2TB
GPU:2xGEFORCE GTX Titan 6GB SLI
PSU: Corsair RM1000
COOLING: Corsair H100i water cooler.
OS: Windows 10 Pro

Welcome to the community, Keegan!

This sounds like a pretty annoying issue, indeed! 🙁 I'd suggest you attempt to use different SATA cables with your HDDs and SSD and see if that will improve the performance. I'd also consider reinstalling Windows and rule out any software-related issue as the source of your struggles.

You should check the health and SMART status of your booting drive (the SSD I assume) using a SSD-specific diagnostic utility. I'd also suggest you download the brand-specific SSD tool to check if you have the latest firmware installed.

Give these a try and let me know how it goes!

I've managed to try out another CPU on the computer and found out that it is indeed the CPU. No one freeze when memtesting or using Prime or anything. Leaving it longer than 24 hours and still hasn't froze. I will replace the cables to my SSD and HDDs just to be sure.

I need to reinstall windows anyway so I'll give that a shot too.

Thank you for your help. I'll post back is the problem seems to continue.
