RAM fills on start-up

I have been having this issue for the past month or so. I'm hoping someone might have a better solution.

My RAM (8 GB of HyperX), reached up to about 95% in a short amount of time about a month ago, so I naturally looked in the task manager and found that nothing out of the ordinary was running/taking up more than about 50 MB. It didn't add up to more than 1 GB, so I shut down my computer for a while, only to find that it was still at 90% when I started it back up.

After trying several other things, I ended up restoring Windows 10 to one of the last updates, and that seemed to fix it...for about a week. It just happened again last week, and again right now. I've been having to restore Windows every time, and it's gotten pretty annoying. Just shutting down the computer doesn't fix it.

The only lead I might have is Geforce Experience. It is the only program that uninstalled itself when I restored Windows, and the only thing that I installed again since then, and my RAM is back full. As of now, i'm not going to reinstall Geforce Experience after I restore Windows and see if that helps.

In case you need my specs, Core i5 4690K, MSI Z97 Gaming 5, EVGA GTX 1070 FTW, HyperX Fury (2X4GB, 1600MHz).

Thank you so much
 
If the memory used shows up as Cached instead of In Use, then it's just Superfetch first introduced in Vista prefetching any commonly used files.

Memory used by disk cache has a low priority and is instantly dropped (the contents don't need to be written to disk as it is just a mirror of what's already on the disk) if any program needs to access a lot of memory. So technically any memory so used is still available for use.

Where would it say Cashed or In Use? Though i'm not sure, I think it might be "In Use" because it takes a big hit while playing games (big fps drops, and lots of freezing/stuttering). Also, not just games, but everything, like Skype and Chrome for example are just overall very slow while the RAM is full. Thanks!
 
Right in Task Manager, on the "Performance" tab, click Memory.

For more details click the link to Resource Monitor on the bottom and then the Memory tab. A big chunk of the bar will be Standby if it's cached, but if it's all In Use scroll through the top box to find the program with a memory leak.

Oh, I see. I just powered on my computer, and it says 4.5 GB in use, about 1.8 GB cached, and about 3.3 GB available. Before I had this issue, and after I restore Windows, it would start with about 20-30% used. Right now, it just started at about 60%.

The usages seem to add up better in the resource monitor. The biggest processes seem to Windows Defender, at about 150 MB, SVCHost (Local) at 145 MB, Chrome at 140 MB, Skype at 90 MB, and many others in the 20-30 range.

So I guess I have three questions from this:
1) If everything seems normal, why is my usage twice as high on startup now than it usually is?
2) Would buying an extra 8 GB, for 16 GB total, help this, or would Windows just assign more stuff to it by default?
3) Do you know of a way to limit how much Cache the RAM can have?

Thanks!
