Running on Vista gives me sporadic BSOD

I’ve been getting BSODs with Vista RC1 and BitComet 0.71. They are random, and I think seem to occur most often when I’m downloading more than one torrent. After the reboot, Vista asks me to run the Memory Diagnostic Tool, but even after running that it says my memory is just fine.

Any ideas why this is happening?

For starters don’t use BC 0.71, it has some major errors. Use 0.70 as it is a stable release. Also keep an eye on your permission settings as people have had problems with that on Vista.
