KAG KAG crashes computer randomly

When playing KAG Beta, my computer sometimes crashes 3-30 seconds after joining a game. (blue screen of death) It happens in multiplayer and singleplayer. It doesn't happen every time, but in about 50% of joins.
This has happened in all versions of KAG Beta, and even in KAG classic, but more rarely there.
Operating system: Windown XP 64-bit
Graphics card: Nvidia Geforce 9500 GT
RAM: 1 GB

Here's logs of one crash (build 935):
I went to singleplayer sandbox, and after 10 seconds computer crashed.

This computer might just be too old and bad for this game though. But just in case someone knows why this might happen.
