OK, that sucks but it's not over yet.
1.) You mention nothing about why all the freezing and warm/cold boots or if you run **Current** up to date anti-virus programs. If you were having unusual problems right before, it is highly likely you picked up a virus or a highjacker adware program. If you haven't done so and you can, run a current updated anti-virus program as well as a current anti-adware program (like Pest Patrol) to insure there are no lingering bad programs.
2.)Depending on operating system, follow the advice above for restoring the OS. Remember, it time consuming and not fun but Microsoft support gives you 5 free technical support calls on every operating system they sell. If you have any questions/doubts, call them and let them walk you through the issue and it's fix for the best possible chance of recovery. Don't even think of calling unless #1 is complete though.
3.)If this doesn't work, look up data recovery companies. Depending on the value of the data, your wife's pictures are special I'm sure, it may be worth it. It's not cheap but neither is divorce! [img]/ubbthreads/images/graemlins/shocked.gif[/img]
