PC locking/freezing | High RAM usage low CPU usage

Starting a week ago, my desktop has started to freeze or lockup randomly. I can not do anything as audio cuts and keyboard/mouse does not work until I manually restart the PC. The times in which the freezes happen are completely random. One day it'll take approximately 54 minutes before it happens, the next time will be hours.

I thought it might be a hardware issue regarding heat from research and experience. All the fans are working correctly. CPU, GPU, and PSU are not hot to the touch and temp readings are in the normal ranges from what I have looked up.

I don't have any specific programs open when the freeze occurs nor is my CPU or RAM usage above 50%.

I have reinstalled recent windows and driver updates, cleared out any new programs/files I have installed in the past month as well as using various anti-virus software programs.

Currently, I have not had a freeze in the past 24 hrs, however, my RAM usage is now at a constant 25%-35% with only Chrome open (this has never been like this). Even after reboots my RAM spikes to the same range while my CPU stays at 5%-15%.

Also currently, without RAM or CPU usage going any higher than 50%-60%, any programs such as Chrome, Discord, Steam, Task Manager will stop responding for various amounts of time but will never be slow in use.

I stopped various services under svchost that could have been causing some spikes but still no change.

Added pictures for Task and Resource manager.

Any advice or help is appreciated.


PC Specs

OS: ...win7 pro x64
GPU: GTX 660
CPU: AMD FX-6300 Six Core
RAM: 8 Gbs

A problematic HDD can be the cause for freezing.
Schedule a check disk
Open a CMD window and type chkdsk c: /f
It will say the drive is in use and if you want to schedule to next start = yes
Reboot. Pay attention on the results, specially bad blocks or bad clusters.

Back to windows, do a system file check
Open a CMD window and type sfc /scannow
