Win XP System Restore Won't Work

I've had this "System Restore" (SR) problem a lot over the last several years (as I've had a lot of computer problems -- seeminlgy "security" related).

 

SR worked for a while, recenlty (last several months).  Now, not (reliably) working again.  Sometimes does -- most times not.

 

[Running Toshiba laptop, Win XP SP3, NIS 2009, GHOST 14.]

 

I'm aware of the issue with SR, regarding NIS "Norton Product Tamper Protection" settings.  I've always turned this  OFF when I create a SR point -- and when I do a SR recovery from such a point.

 

Lately, that doesn't seem to work.

 

Some have suggested running SR in "Safe Mode."  Should I try that?  For both the created and restore?

 

Also, I read here that one should do a "Live Update" after a System Restore.  Is that when one is created? Or used?  Or, both?   And,why?

 

Appreciate any help.

 

Kind Regards,

Robby
