Very high Idle ram usage

[GauntletV2]

So, I'm having an issue with windows where my ram usage is higher than I believe it should be, a lot higher.  I sit at about 70% after booting, and even after dumping my ram will cause it to slowly climb back up to at least 60% over the next hour.  It was at a point where it would actually hit 99%, but after fixing my pagefile from 16gb to 3 gb, it got me to where I am now.  I cant find anything out of place, I dont download anything on this computer, so I couldnt have contracted some shit virus, and I cant fix it.  SO any information would be great!

How recent is this issue? Have you updated windows, installed any drivers or programs? Does anyone else use the computer? Have you run a virus scan? Do you have a Windows backup you can revert to?
