I’ve got an odd issue on my workstation PC - brief specs;

7950X

128GB Ram

4TB SSD

RTX4080

When I first boot my PC, and use it for a few hours it’ll have about 10-14GB of ram “in use” and ~8-12GB “cached”. Everything is perfect, and there are no issues.

Over time, the “cached” amount of ram will gradually increase to encompass the entire amount of RAM. I’ll have something like 12GB in use, and 116GB cached.

Now I know this in itself isn’t unusual, but my PC starts acting super weird. For example, I won’t be able to open Photoshop anymore as it will show as error that there isn’t enough ram (I mean - there’s over 100GB of unused ram, it’s just all “cached”). I also won’t be able to interact with the start menu - I’ll be able to click the start icon to open the menu, but I can’t click anything in the menu - but if I use the keyboard I can interact with stuff. Right clicking on the desktop will cause explorer.exe to take a dump, screen will flash and then the taskbar/explorer.exe will reload.

I’ve tried reinstalling Windows, updating drivers, etc etc. But it still happens. When the entirety of the ram gets cached and things start going weird, I just have to restart the PC and everything will go back to normal.

This doesn’t happen on my 7800X3D based gaming PC, nor on my 3950X based media PC.

Anyone got any ideas before I yeet this thing out of the window?
