Chapter 14 Purchasing a PC or Building Your Own
You Will Learn… • Some guidelines to use when purchasing a PC • How to prepare for assembling a PC yourself • How to assemble a PC from separately purchased parts
Selecting a PC to Meet Your Needs • Consider upgrading if cost of the upgrade does • not exceed half the value of current system Don’t upgrade a computer system older than five years
Alternatives When Selecting a PC • Buy a brand-name PC • Buy a clone • Buy parts and assemble a PC yourself (personally designed clone)
Selecting a PC to Meet Your Needs (Hierarchical) • Identify the intended purpose • Define the functionality needed • Define hardware and software needed to meet • • the functionality Decide on your budget If a clone will meet your needs, do you want to assemble it yourself?
Purchasing a Brand-Name PC versus a Clone • Brand-name Costs more than a clone § Generally provides better after-sales service and additional support § May be more proprietary, making upgrading and repairing more difficult §
Selecting Software • Choose operating system first • Choose application software § § § Functionality Compatibility Training Documentation Upgrade policies Popularity
Selecting Hardware • Most important criteria: Compatibility § Functionality § • Consider motherboard first • Other considerations (eg, Pn. P, modem selection, power supply)
Considerations When Selecting a Total Package • What hardware and software included? • Warranty and return or exchange policy? • On-site or local service available? • ACPI and Energy Star compliant? • What software preinstalled? • What documentation provided? continued…
Considerations When Selecting a Total Package • Manufacturer’s Web site maintained? • Motherboard allow for expansion of RAM? • What expansion slots are not being used? • Can features be disabled? • How much does it cost?
Selecting a Total Package • High-priced to middle-range PCs offer more: Network capability § Expandability § Support § Prior testing §
Why Build Your Own PC? • Knowledge gain • Complete control over every part • Availability of documentation and original • software disks Personal satisfaction
Why Not Build Your Own PC? • • • Takes time High likelihood of encountering problems No overall warranty on assembled product Possibility of selecting components that are incompatible Need access to an experience technician or technical service center Probably won’t save money
Getting Ready for Assembly: Selecting Parts • • • Selecting each component requires reviewing your functionality, compatibility, and budget needs Select motherboard first, then CPU and RAM (all from same local dealer, if possible) Select the case and accompanying power supply Select hard drive and other drives Select video card and other peripherals (mouse, keyboard, monitor)
Getting Ready for Assembly: Final Preparations • Prepare a work area that is well lit and • • uncluttered Read all documentation and plan entire assembly Get questions answered before you begin
Steps for Building a PC 1. Verify that you have all the parts 2. Prepare the computer case • • Install case fans and I/O shield Remove plates covering drive bays and install spacers 3. Install drives 4. Determine proper configuration settings for motherboard; set jumpers and DIP switches continued…
