Look over the info below. That MIGHT be your problem. Though your error message is a bit different and it looks like you didn't have this problem before. If you had less than 4 gig of ram during your first install that could explain why it's occurring now.http://support.microsoft.com/kb/929777
If not that then probably a driver issue. Since it's occurring at the same point and at a time when drivers are being loaded. Maybe try to install with nothing but bare essential installed. No USB devices in particular.
