Hi all,

Recently my computer has been freezing at random intervals, usually during games but sometimes during desktop work. The freeze is not temporary, I have to switch my PSU on and off for my computer to reboot. I reinstalled windows, made sure that my ssd was defragmented, and made sure i had enough space on my computer. Not sure what could be causing this. My OEM Partition is almost full which is a little odd, but I believe this all began when I tried to compress my OS (stupid move btw). I've also made sure that none of my parts are overheating. Any tips on how to fix this?

specs:
gpu:asus strix 1080
cpu: i7 6700k
mb: Gigabyte Z170X-Gaming 5
ssd: samsung evo 850 (250gb where OS is located)
hdd: wd blue 1tb
