I have 4GB RAM and I've checked my FPS but not the netgraph. My FPS hovers around the 60s-70s when just traveling around and goes to the 40s during combat/lots of effects.
The crashes seem very random since they happen at empty areas, crowded areas, big zones, small zones and loading screens. I looked at changing the page file, but it was already at its capacity so I left it alone. Thanks for the suggestion though!
Edit: Found the problem! The RAM sticks themselves were bad so I got new ones now. I'm good to go.
