Google Chrome
GPU is your Graphics card rendering the page/whatever you're looking at. Watching videos/playing games will suck up more RAM from it. What I'm confused about is why when I add them up it only equates to about 450MB of active RAM and you're reporting 3GB. That's a massive discrepancy, so what exactly is reporting the 3GB, Task Manager?
I have always used Chrome no problems for me. Try Opera.
