backup of your crucial files. To do this, you can use a CD-burner, a backup tape system, or a removable disk drive (such as a Jazz, Zip, floppy or flash drive). Keep copies of these backups in another location, just in case you need to perform a disaster recovery. V Firewall Protection: Symantecs Norton personal Firewall keeps personal data in and hackers out. Right out of the box, it makes your PC invisible on the Internet so that hackers cant find it. The programs Intelligent Intrusion prevention technology blocks suspicious Internet traffic. And easy-to-use privacy controls prevent personal information from being sent out without your knowledge. VI Internal/External Component Cleaning: Dust is one of the leading causes of hardware failure. All moving components are thoroughly cleaned and lubricated during service visits. The case is opened and dust is removed from the motherboard and all system boards. The CPU fan, power supply fan and any other board fans are cleaned, lubricated and tested. All data cables are checked to be sure they are securely heated on system boards. CD and floppy drives are opened, cleaned and tested for data transfer. External components such as keyboard, mouse, monitor and printers are cleaned of dust and debris and all cable connections are checked. Connections to surge protectors or UPS are checked. VII Scan and defragment your hard drive on arrive: Your hard drive stores information in open areas of your hard drive. As you delete data on your drive, open space appears. The computer will utilize this open space to store new information. Sometimes information for a particular file or application is separated on a drive into several different locations. The totality of the information may not fit in the open space in one area, so the computer will divide the information into several pieces. When you scan and defragment your hard drive, you are minimizing the risk of having problems and slowdowns caused by separated data on your hard drive. The defragmentation will locate, delete open spaces and place associated files back together again, helping your computer to run smoothly and faster.

Disk Defragmenter


Disk Defragmenter is a system utility for analyzing local volumes (an area of storage on a hard disk. A volume is formatted by using a file system, such as FAT or NTFS, and has a drive letter assigned to it. You can view the content of a volume by clicking its icon in windows Explorer or in My Computer. a single hard disk can have multiple volumes, and volumes can also span multiple disks) and locating and consolidating fragmented files and folders. You can also defragment (Defragmentation is the process of rewriting parts of a file to contiguous sectors on a hard disk to increase the speed of access and retrieval. When files are updated, the computer tends to save these updates on the largest continuous space on the hard disk, which is often on a different sector than other parts of the file. When files are thus fragmented, the computer must search the hard disk each time the file is opened to find all of the files parts, which slows down response time) disks from a command line using the defrag command. The best practices for fragmenting a volume are enumerated below.  Analyzing before defragmenting Analyze volumes before defragmenting them. After analyzing a volume, a dialog box tells you the percentage of fragmented files and folders on the volume and recommends whether to defragment the volume. Analyze volumes regularly and defragment them only when Disk Defragmenter recommends it. A good guideline is to analyze volumes at least once a week. If you seldom need to defragment volumes, analyze volumes monthly instead of weekly.   Analyzing after large numbers of files are added Volumes might become excessively fragmented when users add a large number of files or folders, so be sure to analyze volumes after this happens. Generally, volumes on busy file servers should be defragmented more often than those on single-user workstations.
