Question Desktop Computer Freezing

[strocked]

My computer freezes up for about a minute at a time. It starts with 10 seconds of unresponsiveness, then the mouse stops moving. After this minute is up, it works fine for about 5 minutes give or take and then repeats.

This has been going on for about two years. I am completely lost as to what is causing this issue as well. Even with a completely clean install of windows 10, the issue still persists.

When this full system freeze occurs, I have observed a large performance spike in task manager, but have been unable to find which program is causing this spike. I have not observed any change in cpu or gpu temperature when it occurs.

Here are my specs:
CPU: intel i5-4690k
Motherboard: Asus Z97-A
RAM: 16 GB DDR3 (2x 8GB)
CPU Cooler: Cooler Master Hyper 212 EVO
Video Card: Asus Strix GTX 970
PSU: EVGA SuperNOVA 80+ GOLD
Hard Drives: SanDisk Z400s 2.5" 64GB SATA III MLC Internal Solid State Drive
OS: Windows 10 64-bit
Case: Fractal Design Define XL R2 Black Silent
Keyboard: Razer Blackwidow Chroma
Mouse: Razer Mamba Wireless
Headset: Razer Kraken V2

Steps I have taken:

1. Uninstall and Re-install many drivers. Mainly nvidia drivers.
2. Turning Link-State Power Management Off
3. Using PC without gpu
4. Re-Applying CPU Thermal Paste
5. Re-Installing Windows on Different Drives
6. Changing Ram to Different Slots
7. Using Different Monitor Inputs
8. Many small things

My cpu and gpu temperatures seem normal. They are shown in the image below:

My ram is approximately four years old, but running memtest yields no errors. The hard drive can be removed as a variable, as I have tested more than one windows installation on different drives independent from each other. I ran a hard drive health test tool which can be shown in the image link. I also ran a full bitdefender scan on my main C: drive, and the problem still persists even on a completely clean windows installation, so malware couldn't be the issue. Thanks for replying.
