My computer running Win98. And when ever i try to shut it down, it will go into frozen status instead of showing message "windows is shutting down" and auto power off after that. I ran the Norton Ultilities and it told me that my Master Boot Record (Or something in that nature) has error. How do i fix it without reformatting hardrive. Right now, I have to hit the power switch to turn cpu off and have to run scandisk when turn cpu back on because of the unproperly shut down the computer. thanks.
