In task manager it says 95-98% of my RAM is being used when I'm idle or in browser, about 7,5 out of my 8GB. I've built a pretty good system with Windows 8.1 on it, and this is the first time this has occured... I tried playing CSGO but I kept getting lag spikes (I'm using Intel HD 4600, didn't get a GPU yet). Also, my CPU is on 3-10% usage so I supposse thats okay. How to fix this bullshit?
