I just build this pc about a month ago, at first dont have any issues at all but after a few weeks I notice that my computer is a bit laggy while playing BF4 then I looked at task manager and saw that my ram usage is at 90%. And I though that was normal thing because I was playing games but a few days later my usage suddenly increase to 90% again but this time I wasnt playing any games (was Facebooking) and even my computer is Idle, the only way to fix this problem is restarting my pc but this issue becomes more often and I have restart my pc every time this happen. What is wrong with it?
I have 8Gb Gskill Ripjaws x and I7 4790, running windows 7 64 bit,1TB HDD
