Technical Support for PCs
A 3/4-Day Hands-on Course

If Support, Maintenance or Troubleshooting are your concerns then this is the course for you.

As the number of PCs within organisations grows so does the load on technical support. To provide effective timely support a thorough understanding of the PC, its hardware and environment is needed.

This intensive hands-on course provides the required in-depth understanding of the PC, its major components and how they are configured, tested and maintained. At each stage the course will reflect the fact that Windows (95/98/NT2000) is the most likely desktop operating system in use.

Hands-on means just that. During the course you will build a Pentium PC from scratch, installing and testing each subsystem. This is the best way to learn and to be confident that you really understand the PC.

 Hands-on
A skeleton Pentium will be built and tested. Once this is working various additional components will be added including the hard disk, a CD-ROM, serial communications ports, a network interface card and sound card. The course is structured to give you ample opportunity to learn, practise and perfect the skills which you need but which are not easily picked up in the work environment.

Who should attend
Support and Help Desk Personnel. Providing effective support involves understanding the hardware as well as the software.
PC Users and Managers who have difficulty in getting technical support
LAN Administrators A good understanding of the hardware is a real benefit to LAN supervisors.
UNIX Support As the PC becomes the standard desktop computer many UNIX people need to include an understanding of PC hardware among their skills.
PC Procurement Specifying PCs requires a good understanding of the issues if they are to make the correct purchasing decision and avoid expensive mistakes
A+ is the industry recognised certification for PC hardware. This course helps you prepare for the core and DOS/Windows sections of the A+ exam.

KEY Benefits include

  • Reducing support costs
  • Really understanding the PC
  • Taking effective action quickly
  • Understanding the symptoms, the BEEP and POST codes and other vital signs of life
  • Configuring PCs for optimum performance
  • Providing an efficient, Professional Support Service Increasing the efficiency of the whole department

Hands-on Content

This is a hands-on course and the following summarises the main hands-on content.
Building a Pentium based PC. The CMOS will be backed up and the PC will be carefully disassembled, taking into account static and other hazards. The major components will then be examined in detail. Subsequently the PC will be rebuilt and tested. Understand the main partition issues and Partition and Format the hard disk. Additional I/O cards will then be installed taking into account interrupt and DMA conflicts. Both legacy and Plug and Play cards will be used. A Network Interface card will be configured and tested. The PCs will be cabled and the complete network tested. Understand the interface issues and install a CD-ROM.

Advanced Diagnostic Software will be used throughout the course to help identify hardware and software problems. You will learn how to identify the factors which affect hard Disk Performance and use optimising tools such as the defragmenter.

Changing the CMOS to reflect an altered configuration and enable/disable shadow Ram. Undertake a Flash BIOS upgrade and understand the issues.

Memory is a major concern. Starting by clearly defining Conventional, Expanded and Extended memory we will examine the memory’s contents and use advanced Memory Diagnostic software to test the actual memory modules.

Data recovery is provided by both DOS and many third party utilities. Using these depends on a clear understanding of how DOS\Windows stores data. You will recover system disks which will not boot and recover files which have been lost and which DOS or Windows cannot recover. You will discover how and when to use Scandisk and CHKDSK. CHKDSK is a powerful utility but using it incorrectly can be fatal.

Windows 9x/2000 supports Plug and Play. Install Windows 95/98 and install and test a Plug and Play adapter, understand the issues when using legacy cards.

Learn how to edit and backup the Windows registry.
