Ram usage goes high after a while?

I have 4GB and windows vista 32 bit and my ram usage goes high after a while like when im done playing my games like Call Of Duty? I am upgrading to 64-bit soon but i never used to have this problem like when i used to play my games it didnt stutter or so called lag i dont know if its cause i dont have fast enough ram or what. I ordered new ram yesterday the same 4GB but a better kind so i dont know if this will help or not but i know when i get my system up to 64-bit i will maybe wont have any problems because right now i only can use 3.25GB but i use 2gb of that 3.25 gb.

Post a screenshot of Task Manager - Performance tab when the problem occurs. The is will provide some much needed information.

Thats when its not high

This is when im done playing my games and it stays that way until i restart my pc

And if you guys say its fine its not because i like to game but i cant really when it gets like that.

There is nothing wrong with the memory usage in either screenshot. But I do find it odd that the usage is higher in the second, if that is actually during gameplay.

But the CPU usage is very high in both. Note that there is no relationship between CPU usage and memory usage. Look in task Manager -processes tab to see which process (if any) is responsible.

Are you dumb i posted a screen hot when i was not gaming and when i was done gameing i posted antother screenshot what are you retarded. JEESH
