5. Hardware Installation and Compatibility Problems Hardware problems can occur: During installation of new systems During upgrades of existing systems Incompatible components are unable to operate together in the same system May be due to incorrect installation Example: Incompatible RAM memory modules A Guide to Computer User Support for Help Desk & Support Specialists, Fourth Edition 5

6. Hardware Configuration Problems Hardware configuration problems result when hardware component settings are incorrect for a specific environment Were more common before Plug and Play standards Example: Incorrect graphics display card settings A Guide to Computer User Support for Help Desk & Support Specialists, Fourth Edition 6

7. Plug and Play Standards Plug and Play standards: industry-wide agreements among hardware and operating system vendors about hardware installation and configuration options Specify the communication methods an operating system uses to recognize and incorporate hardware components into an operational system Can help load appropriate drivers, but do not always automatically adjust software settings to take maximum advantage of new hardware’s capabilities A Guide to Computer User Support for Help Desk & Support Specialists, Fourth Edition 7

8. Hardware Malfunctions Actual malfunctions are a small percentage of hardware problems Can be reduced with a burn-in test period A 48- to 72-hour period during which a new computer is operated continuously Can discover obvious problems and identify components whose operation is: Marginal Temperature sensitive Example: Inoperative keyboard keys A Guide to Computer User Support for Help Desk & Support Specialists, Fourth Edition 8

9. Hardware Malfunctions (continued) Most likely to fail Electromechanical devices that have moving parts Examples: Hard disk drive; printer Least likely to fail Electronic components Examples: CPU; RAM memory Hardware diagnostic tools can help identify system burn-in and hardware malfunctions Example: Hardware diagnosis utilities from PC-Diag A Guide to Computer User Support for Help Desk & Support Specialists, Fourth Edition 9

11. Software Problems Installation and compatibility problems Configuration problems Software bugs Performance problems A Guide to Computer User Support for Help Desk & Support Specialists, Fourth Edition 11

12. Software Installation and Compatibility Not all software installs automatically Vendor solution: Installation software, a utility that aids in the installation of other software packages Examines hardware configuration to determine whether hardware and software are compatible Creates folders with correct path names Sets configuration options in software to match hardware Copies files to correct folders Updates Windows Registry and other start-up files Example: Applications software incompatible with new operating system version A Guide to Computer User Support for Help Desk & Support Specialists, Fourth Edition 12

13. Software Installation and Compatibility (continued) Shareware Evaluation or trial period of 10-45 days before purchase May produce conflicts with other software Freeware Free for personal use (may charge for commercial version) May not be exhaustively tested for compatibility and conflicts with other software Open Source Free for personal or business use Designed and developed collaboratively by programmers May carry OSI design certification A Guide to Computer User Support for Help Desk & Support Specialists, Fourth Edition 13

14. Software Installation and Compatibility (continued) Conflict occurs when two software packages use systems resources (CPU, memory, peripheral devices) in different and incompatible ways Result of conflicts: Inoperable system Poor performance A Guide to Computer User Support for Help Desk & Support Specialists, Fourth Edition 14

15. Software Configuration Problems Result when software options are not set for the specific operating environment or hardware May occur when users: Install or upgrade new hardware or software Attempt to use a software feature for the first time Attempt to modify configuration information in the system Windows Registry or other startup files Example: Installation of new application changes default file associations in operating system A Guide to Computer User Support for Help Desk & Support Specialists, Fourth Edition 15

16. Software Bugs Bug: a major error in a program due to: Programmers’ coding mistakes Inability to anticipate every situation Occur more often in custom-written programs and programs written for a limited market segment Occur most often in infrequently used features of a program Reduced through extensive beta testing Example: Incorrect format of large dollar amounts in accounting program A Guide to Computer User Support for Help Desk & Support Specialists, Fourth Edition 16

17. How Vendors Fix Bugs and Upgrade Their Software Patch: a replacement for one or a few modules in a software package that fixes known bugs Usually designated by adding a digit or letter to a version number Update: a bug fix software release Repairs known bugs in a previous version Some vendors offer automatic updates via the Internet to keep programs up to date A Guide to Computer User Support for Help Desk & Support Specialists, Fourth Edition 17

18. How Vendors Fix Bugs and Upgrade Their Software (continued) Service Pack (or Service Release): contains both updates and patches to fix problems with a version of a program New release: an updated version of a program Contains new features the previous release did not have New version: contains significant new features Usually the result of a substantially rewritten program Upgrade: a new version of an existing program Sold at a lower price to owners of a previous version of the program A Guide to Computer User Support for Help Desk & Support Specialists, Fourth Edition 18

19. Example of Software Release Numbering 2.0 First release of a new version May be offered as an upgrade for purchasers of version 1.0 2.1 An update release with new features 2.11 A bug-fix release; alternate: 2.1A 2.1 SR-1 An updated version with a service release installed Some vendors use year of release as a primary version designation (e.g., Office 2007) A Guide to Computer User Support for Help Desk & Support Specialists, Fourth Edition 19

20. Installing Software Patches Prior to installing a software patch or service pack Verify that the patch applies to the software on a user’s system Install patches in sequence specified by vendor Make a backup copy of the original program After installing a software patch Keep a record of patches installed in case software needs to be reinstalled A Guide to Computer User Support for Help Desk & Support Specialists, Fourth Edition 20

21. How Vendors Fix Bugs and Upgrade Their Software (continued) Workaround: a procedure or operation that accomplishes the same result as an original feature that does not work Example: Same operation may be accomplished alternately via: Keyboard command Menu command Toolbar icon Shortcut keys A Guide to Computer User Support for Help Desk & Support Specialists, Fourth Edition 21

22. Software Performance Problems System is operational but does not operate as efficiently as it can or should Often involves the interaction between hardware and software A Guide to Computer User Support for Help Desk & Support Specialists, Fourth Edition 22

23. Software Performance Problems Performance problems occur when a computer is: Operational but performance is inefficient Often result from a combination of hardware and software problems Example: Slow read/write times on hard disk drive may be due to: Lack of free space on drive Fragmented files Wasted space on drive Insufficient RAM memory results in disk accesses Malware infection A Guide to Computer User Support for Help Desk & Support Specialists, Fourth Edition 23

24. User Problems Mistakes Misunderstandings Wrong products Inadequate information or training Forgotten information A Guide to Computer User Support for Help Desk & Support Specialists, Fourth Edition 24
