Question All my storage suddenly 100% usage

Apr 29, 2020
Hi forum (forgive my English)

So my pc ran into an issue when all of my pc storage (1 SSD, 2 HDD's) suddenly going 100% usage on task manager and it makes my pc froze and nothing I can do except to restart the pc.
This problem only happen while I'm recording my gameplay with OBS, sometimes happen while playing games without OBS recording, but I often record my gameplay before and never ran into that issue until a couple of days now.

My pc specs :

CPU: FX 8350
GPU: HIS R9 280x
RAM: 16gb
Storage : 1 SSD PNY 120gb, 2x 1TB WD Black
Mobo : Gigabyte GA-78LMT-USB3 R2
OS: Windows 10 Pro 1909 Build 18363.778

Any help appreciated, thanks.

So far I've tried, disable SysMain (superfetch), changing MSI value to 0, resetting virtual memory, trim SSD, defrags my two HDD's, disable compattelrunner, but the problem still exist.
My last resort was I finally changed my SSD (OS drive) to a brand new one, because I was shocked when I check on HD Sentinel, my SSD health was at 9%, and in hope that the problem will be gone. Turns out the problem still there but this time it was way less than before. I don't know what else should I do at the moment.
