Hello there,
So I just bought a new computer from HP.
This one: http://www.shopping.hp.com/en_US/home-office/-/products/Laptops/HP-ENVY/E8A23UA?HP-ENVY-17-j184nr-Notebook-PC-ENERGY-STAR-
8 GB of memory.
When I got it I started playing Titanfall, within a couple of minutes I got a popup message that said I am out of memory. and my background turned red so I couldn't click on any icons. But I went back to play and it played fine. I opened up task manager to see if I was really maxing out my memory while playing. It was capped out at 2 GB

I realize now as I am writing this that my video card is a NVIDIA GeForce GT 750M (2 GB DDR3 dedicated, up to 4 GB) as per the HP site. Question 1: does this mean for me?

Question 2: As I was on the phone with HP tech support the lady on the other side took control of the computer and changed the virtual memory from 0 to an initial size of 12288 MB and a Maximum of 49152 MB. After she did this my computer started running very hot in game, but my memory usage bumped up to about 3.8 or 3.9 and I still get the popup window but not the red background. What does this all mean!?

Any help to allow my to utilize more memory but not turn my computer into a hot box is greatly appreciated. Thoughts?
