Washington (dpa) - Over time, Microsoft's Outlook Express, the popular e-mail program, can develop file-based problems that prevent your e-mail messages from displaying properly - or at all. To fix the problem, you need to perform an operation called "compacting folders." From the File menu, click Folder ... Compact All Folders. Outlook Express will take a few minutes to reduce the size of its e- mail indexes, and afterwards your e-mail messages should display properly. Make a habit of compacting folders every month or so.

About once a month, you should remove the case from your PC, get out a vacuum cleaner, and gently vacuum out the inside of your PC. Also remove obvious dust that covers external vents. (dpa)
