Hi, ever since around Feburary, my PC began to freeze at random intervals in the span of 1-2 days between each freeze. The system would run perfectly fine until suddenly the system completely locks up, with the audio suddenly stopping, resulting in me having hold down the power button to shut it down.
I can't find any indication of where to start fixing it, I've ran malware scans with no threats found, could this be a hardware issue?

Thanks.

System Specs:
Motherboard- Gigabyte 990fxa-ud5
GPU- PaLIT GTX 1080 Super Jetstream Edition
CPU - AMD FX 8350 4Ghz
RAM - 16gb DDR3
PSU - Corsair 600W
Hard Drive - Seagate 2tb SSHD
 


Temps (Idle):
CPU - 40°C
Motherboard - 41°C
GPU - 48°C
Hard Drive - 32°C

CrystalDiskInfo says that the SSHD's health status is good, Emsisoft also did not detect any malware. I have yet to try HitmanPro though which I will soon.
