A very nice error eh? Thing is that it doesn't tell anything about what is going on; this error is spawned on a gazillion of situations. Often, this error points at a hardware stability issue, but there's no garantuee in that.
Can you perhaps give us some more information on your system? Things like the components in it (or a model number if you're using an OEM system). And maybe you overclocked something? Or your system is running too hot?
