windows restarts when using ms backup

[Splower]

 :-?
I always used msbackup before.  Now I had to format my computer and start over.  Everytime I am using the ms backup utility my screen goes black and restarts???  It is not happening with any other program.
It happens at different times while I am using the utility.  Sometimes during backup, sometimes while I am programming it in.
Please help.

Using windows 2000.  Like always.  Using Telus security like before.  Use mozilla and google spam blockers and such.  All same as before.
