I installed samsung 840evo 120gb into my computer and now a warning that says i dont have enough memory and need to close a program (game). I dont know what caused this as it never happened to me before the ssd. Before installing this ssd my memory usage was very low but now it's constantly above 1 gb. Is there a way to fix this or do i need to buy more ram?

i have:
intel i5 2500k
asus z77a
4 gb gskill ripjaws ram
powercolor hd7850 2gb
2 hdds
