It\'s not a problem, finding your system specs is quite easy :) You can right-click on \"My Computer\" and hit Properties, and under \"Computer:\" you\'ll see your processor type, speed, and your RAM. If you don\'t know what graphics card you have, point to the Start button and click Run. Type \"dxdiag\" (no quotes) in the box and press return. In the new window, go to the Display tab, and read \"Name\" and \"Manufacturer\". \"Name\" is the name and model of your card, and \"Manufacturer\"... is self-explanatory ;)
How is it happening that you are falling off the world and dying? Can you detail when this happens? Is it random, so you could be just standing around just chatting, or are you climbing hills?
It seems that not everything about the \"You should not be able to see this\" message is known, but the usual assumption is that it is something odd with your connection. Hm.. someone else will have to come along and offer some suggestions on that issue.
