i've been dealing with this issue for months and i've tried so many solutions
basically, sometimes* when trying to read from or write to the harddrive, it kinda 'locks up', freezing the entire computer sometimes for around 1-30 seconds. insanely annoying.
this pretty much makes my computer really hard to use or even impossible to use if i can barely do anything on it anymore due to this goddamn issue.
when i'm doing something entirely dependant to the harddrive, such as using a screen recorder, rendering a video or even copying files, it becomes impossible as the system just freezes.
*for around 1-2 weeks it keeps freezing, but then around a month of not freezing at all.
harddrives i have:


image:
see: both disks i have are affected. note the disk transfer rate; its completely blank when disk's active time is 100%, and only does very little transferring when not frozen. CPU is shown as it appears to spike at the only moment when the disk isn't frozen, showing that it's freezing everything else on my computer.

things i've tried already:
- checking cables in computer
- disabling 'superfetch' service
- disabling 'windows search' service
- restarting (you think i've kept my computer on for months?)
- removing resource-heavy programs (disabling steam made the freezes less frequent)
- changing 'power plan' options, setting disks to perform as high as possible at all times
- updating storage spaces controller drivers. right now i'm using the windows default, the motherboard i have (asus m5a78l-m) doesn't have any drivers for this higher then windows 7, and the windows 7 drivers bring up this error.
- checking temperature, both harddrives aren't overheating
- uninstalling windows 10 store apps (Candy Crush)
- manually setting the virtual paging file instead of letting windows 10 do it
- checking HDD health (completely healthy apparently)
- checking for viruses/malware
- changing SATA type in BIOS (caused windows 10 to bluescreen)
- running memtest, no errors/faults whatsoever
- i've probably forgotton a bunch of other things i've tried to solve this
computer specs if needed
