So, the PROBLEM I am running into is that when my COMPUTER is running for an extended period of time (can't gauge the timeframe well. Maybe an average of 7 hours of uptime), I eventually run into insane slowdown. Of COURSE, I'm trying to end any high tasks in Task Manager that could be sucking up this much RAM, but that doesn't seem to be the culprit. I wish I could give you the reproduction steps to what gets it in that state, but I was wondering if anyone had any ideas on why this was happening, what I need to be on the lookout for, and some ways to fix it. I can't tell if I have a memory leak, a malicious program, or something else.

A) When the slowdown occurs, I look at my Task Manager, and sort the Processes by the Memory % descending. I see it is calculating around 99% total usage. The first lookover is that a lot of processes are not using a lot of memory, so I don't know 99% of it is being used all of a sudden.
B) I basically need to power cycle my machine to return it to normal, until it happens again.
C) When I open the Resource Monitor and watch the Memory Tab. Even when I idle, I see the Physical Memory in use going up
D) Tried to look at some guides to see if they could address my issue:

Here are my computer specs:
- Windows 10 Pro 64-bit
- Intel(R) Core(TM) i7-9700K CPU 3.60GHz Processor
- 32 GB RAM (between two 16GB CORSAIR DDR4 RAM sticks)
- MSI PRO Z390-A PRO LGA 1151 (300 Series) Intel Z390 SATA 6Gb/s ATX Intel Motherboard
- MSI RTX 2060 GAMING Z 6G GeForce Graphics Card
- SAMSUNG SSD 970 EVO 1TB

Here are some things I did while I was attempting to troubleshoot:
1. Originally had 16 GB of RAM. Bought a new stick and replaced it to see if I had faulty RAM. It happened again, so I inserted both. That is why I now have 32 GB of RAM
2. Ran a virus/malware scan with Avast antivirus, Malwarebytes, and SuperAntiSpyware. No viruses or malware was found.
3. Ran a disk cleanup and fixed broken registries with CCleaner Pro
4. Disabled some startup programs
5. Modified the COMPUTER\HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\Ndu\Start registry value from 2 to 4
6. Modified the COMPUTER\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\ClearPageFileAtShutdown registry value from 0 to 1
7. Stopped & Disabled the SysMain service
8. Running the following commands in Windows Command Prompt
- Dism /Online /Cleanup-Image /CheckHealth
- Dism /Online /Cleanup-Image /ScanHealth
- Dism /Online /Cleanup-Image /RestoreHealth
- SFC /SCANNOW
9. Enabled Google Chrome hardware acceleration (it was off)
10. In Google Chrome, turned off "Preload pages for faster browsing and searching"
11. Updated all drivers I could with CCleaner Pro
- This caused some issues, so I had to do a System Restore
12. Updated the graphic card's drivers in NVIDIA GeForce Experience
13. Ran Windows Memory Diagnostic to see if there were any issues (there weren't any)
14. Disabling "Automatically manage paging file size for all drives" via Virtual Memory

I'm also going to link some screenshots I managed to grab of the usage before I noticed the slowdown and eventual crash happening:
