[SOLVED] I have 16gb or ram but only 4.5gb is being used?

Randomly last week my PC started to slow down and stutter. Certain application can't run, Any game cant run unless if I turn off the majority of settings. I have tried a good few things but nothing works. I have also run the memtest86 and it came out with no faults.
Specs
GPU - Gigabyte Geforece RTX 2060 OC
CPU - AMD Ryzen 7 2700X Eight-Core Processor
RAM- Corsair Vengeance LPX 16g (2x8) DDR4 3200MHz
System- windows 10 64 bit
storage - ssd 120g hhd 2tb
Motherboard - Gigabyte B450 DS3H


-------
From what I can tell it ism't using enough of my ram. When in game my ram usage goes upto 90-95 percent while the game is only using just over 2 g of ram. The game freezes and stutters sometimes just crashing.
This is what my system information panel says about it.

Installed Physical Memory (RAM) 16.0 GB
Total Physical Memory 7.95 GB
Available Physical Memory 3.56 GB
Total Virtual Memory 17.8 GB
Available Virtual Memory 9.21 GB
Page File Space 9.82 GB
(The available virtual memory was much worse but has shot up after messing around in settings and many hard restarts)
If someone knows a way to fix this it would be much appreciated.

PSU: make, model, wattage, age, condition (original, new, refurbished, used)?

How full is that 120 GB SSD? Make and model? Is that SSD the boot drive?

Look in Reliability History and Event Viewer.

Either one or both may be capturing error codes, warnings, or even informational events when the problems occur.

PSU- Corsair CP-9020177-UK RM550x 80 PLUS Gold 550 W Fully Modular ATX Power Supply.
The whole setup was made in 2020 just before COVID with all new parts.
The SSD is an Kingston A400 and has about 25g free, it was alot less but I cleared space hoping it would do something but no luck. (Yes it's the boot drive)

The HDD has a good amount of room left.

I've checked both event viewer and relability history and from what I see there's nothing relating but then again it's the first time I've looked at either so I could be missing something.

How did you clear space? Disk Cleanup? Or some other tool/utility?

Thinking that, overtime with Windows, etc.. that the 120 GB has been outgrown....

Let Windows manage virtual memory - determine if that makes a difference.

Use Resource Monitor to observe memory and disk usage. First before gaming and then while gaming.

Objective being to determine the resources being used and what is using any given resource.

Reading back I am also wondering about physical memory. "Missing module"?

What does using "WIN" + "I" > System > About > Installed RAM = ?

Power down, unplug, open the case.

Clean out dust and debris.

Verify by sight and feel that all connectors, cards, RAM, and jumpers are fully and firmly seated in place.
