This happens when you don't have enough ram and you need to use too much of your page file (which I believe is a small portion of your hard drive that can be used by your RAM to store stuff that it doesn't currently need but that it may need to recall later). The same thing happened to me on my old computer when I played TF2, because it only had 1GB of ram. I guess you could increase your page file, but you'll need to look up how to do that because I don't know how. An even better solution is to just buy more ram. Or you could probably just do nothing, because nothing bad actually happened to me other than having the red message up in the corner lol.
It has nothing to do with your graphics card, marcem.
