without spending time to pinpoint the problems, is formatting your computer an options?? have you try last known good configuration? worst case will be getting a new HD and install winxp and use ur exicting hd as 2nd hd, therefore, u won't loss any data. if really needs the org system back, spent some $$ to get a tech to solve it for u onsite or bring it in to a computer store where they have those kind of service.
my computer has crashed, and when i turn my computer back on it goes to the screen where i can choose safe mode, start windoews normally etc. except when i choose one of these options it starts for a bit the ends up at that screen again. My computer is windows xp. If anyone has any sugestions it would help alot thanks.
