I've updated the graphics drivers, reloaded the game, defragged the computer, checked the memory, and was about to lower the sound. I doubt this will fix it, however, as I've been researching similar problems on the boards.
Specifically, the effects are thus: I will be playing, the screen will freeze. Sometimes the computer goes from the frozen screen to black to Windows Startup screen.
Sometimes the screen has little blocks all over it, sort of like what an old DOS hex-editor used to look like, greenish-bluish-purplish. THIS kind of concerned me. Then it goes from that to frozen, or black. Ctrl-alt-delete makes the thing restart instead of taking me back to windows, even if only pressed once. My system more than meets the recommended requirements.
I even added a room fan to hit the bottom/back of my laptop where the three fans are, and it still kicked me, the computer felt much cooler than it sometimes does, so I doubt it's heat.
Could anyone tell me what that hex-editor screen might mean, or what it is? Haven't seen that before with any other program, and it is only happening when I'm running Guild Wars.
Thanks.

btw, I think the company will fix it. Another thread reported about half of the people playing guild wars and reading these boards are having this problem. Here's to hoping!
