Can you tell me what nvidia drivers you have for your vista and xp? I have reinstalled vista and xp 6 times so far. I install XP first then install vista 64 which replaces the xp boot manager and I select earlier version of windows during boot. Also, are you using the latest intel drivers or the one's off the abit cd?

Thanks for your response...this is annoying I tried booting from vista into XP in safe mode and it didn't crash, so I suspect you are right about the drivers.
