Know your system. Help-desk people will want that info. Make an emergency boot disk.
Some computers come with a boot disk.
This is a disk that allows you to restart from the floppy drive if there's a problem with your hard drive. You can make a boot disk automatically with Norton Utilities . Tune your hard drive regularly. Scan your hard drive surface for bad sectors and run a defragmentation program to make file storage more efficient. Store with a plan.
