My PC with Win XP Pro is locked in a continuous rebooting without loading Windows. As soon as Windows tries to open a get a blue screen for a fraction of a second (too short to read) and then the PC reboots. The same process continues over and over. When the blue screen appears I can see a statement about a Registry problem but the screen goes away so fast I cannot read anything more. Can anyone help. This is the second time I've had this problem in the last 6 months. Last time the only fix was to completely reinstall Win XP PRO and all applications software.
