Hi,

I am getting Blue screen of Death when playing Warcraft 3, Dota in Garena.
It occurs occasionally, only once or twice in a day.

This is my computer Spec:

M/B: MSI P43 Neo3F
RAM: 2 X Kingston PC2-6400 2GB
Video: Leadtek NVIDIA GeForece GTX 260

OS: Windows XP SP3

I have attached the most recent minidump file. I would greatly appreciate if anyone can help.
