Lots of text, but way faster than I could read it.

It could be a RAM issue - that is the most common error that causes blue screens - how are your timings, and all that in the bios - did you change anything recently?
I did put 4 megs of G.Skill memory in it, put I pulled it and put back the tried and trued original 2 megs back in, no luck.

If not, then it is likely something to do with the cards and/or drivers. Do you have old drivers in there?
I don't know if I have the old drivers still installed (probably so though), after I put the 5870 in there I installed the current ones, so I guess the old one is still there?

Did you do a complete uninstall of the old drivers first, before installing the new ones?
I didn't

Also, it works better if you get one of the cards in there working good, before you put the other one in (for crossfire or just crunching on two).
Someone told me that crossfiring them was not a good idea for BOINC. I have no idea.
