so after trial and error and a few fixes
i no longer dual boot vista
i am running straight leopard
my final problem with getting my system to stop crashing when doing high stress work loads on the cpu
and my problem was a 1gb ram chip that i had in my system it was different than the other 3 gb sticks in my system
so now i am totally leopard no more windows (thank god)

just thought i would share
i have not had a system crash in a good 3 hours
i usually have to restart every hour but gone strong
