So I build my new PC just under two months ago and everything was going smoothly. FPS and performance great.
Suddenly today I notice its starting to be really jolty/micro freezes. For context my main game is WoW. Up till today 0 issues.i check the in game meters and FPS is still healthy but I'm still getting microfreezes, loading screens pause and the cursor sometimes changes to the Windows blue loading wheel which is never a good sign when in a game! This is when I notice RAM usage is at 100%. I've just upgraded to 32GB and there is no chance that WoW and chrome (only two open apps, chrome with a singular tab) should cause that? Especially as it was fine just a day ago playing WoW, multiple tabs open with YouTube etc.

I've tried a brief read of processes and I don't see anything unusual but there are hundreds of little ones?

Any suggestions?

Edit (specs):
Ryzen 7 7800X3D
32GB Corsair Vengeance DDR5
Nvidia GTX4070Ti Super
Asus ROG Strix B650E-F

It sounds like you probably have a memory leak in one of your applications, which could be due to a bad update, or a bugged tab/website. It is not always shown with a memory leak because the app is failing to release the memory properly, though it is strange it would happen after you just upgraded.
 
So even with battlenet and wow closed which was the biggest user I am at 93%.
Details in task manager is showing 29/31.2GB.
Nothing bigger than 304mb which is Discord currently
 
Update: seems to be Windows that fixed itself. I did the Windows reset function where it does a self repair but keeps your programs etc. After it's now back down to 25% idle memory usage and capping at 55% with WoW and Chrome open

I noticed a lot of the small processes that were there (and I'm talking dozens) are now no longer showing. Any idea what could cause this to avoid it in the future?

Could quite possibly be windows update
It's got a habit of sometimes messing stuff up

Probably a good time to suggest
If you don't have an image backup or clone
Of your drive
You should make one
The reset function won't always get you
Out of trouble

If it was a memory leak it can be caused by anything, since any application (including Windows itself) could have had a dodgy auto-update, but shutting down and rebooting the PC should usually fix it until the app has been running for awhile again. If an auto-update causes the problem, then another auto-update can fix the problem, unless it is caused by corruption that only an uninstall/reinstall can fix.
 
Also worth noting that if you Start Menu->Shut Down your PC every night then under default windows settings fast startup is enabled which means the PC doesn't actually end running processes it just hibernates.

So when you power up again nothing has been cleanly shutdown and restarted, leaving any ****** processes still in a ****** state.

A Start Menu->Restart will do a full shutdown and power on again. Or you can disable fast restart in the power settings.
 
If you don't want/need hibernate
Just delete the hyberfil.sys file
I have always done that
Bit of a habit as the more ram you have
The bigger the file is
So I have always deleted it to lower my backup
Image file size
I just use sleep instead if I don't do a shutdown
It's not as important nowadays
Since I have all nvme drives the extra size gets written
In a few seconds
But old habits die hard I guess

I did not actually know this. Will definitely look to change this, I usually shut down because I want a full restart every day
