Colif :
i can't read minidumps but this will give us a look at errors and maybe help while I wait for someone to decode the dumps
Can you download and run
who crashed - it will give us a glimpse of the errors you getting and might help us solve them
Copy/paste summary in here and I see what I can do
they are likely to be drivers. We shall see
