PC Consultation
There are a lot of PCs out there to choose from, all with
fantastic hardware specifications with lots of features and what is called "added
value" software installed. Some PCs are so cheap that it's hard to believe while
others are priced from midrange to whaaat!! OK.. so you begin to compare
prices and features and then wonder why there are price differences when the
features look the same. The truth is they are all
different in areas of hardware performance, what software is installed and
compatibilities with other external components. And unfortunately some PC manufacturers
build their systems in such a way that customers must buy add-on
software and external accessories only from them at significantly higher
prices. Well then how do I select a
system you might ask?
Approaching the selection of a PC buy comparing features is definitely the
wrong way. A consultation first determines what you want to accomplish with
the new PC. Do you need word processing, email, internet access, need
high/medium/low performance, are there a lot of files going to be stored,
what drive access speed is needed, is
the PC used occasionally or daily and so on. Once the requirements have been
determined, then the requirements for each component can be determined. All PCs
can be broken down into the following list of basic components. Each
component varies from manufacturer to manufacturer as far as features which fill different needs. The list gives
an example of some of the different features each part can have.
•
Case - # devices the power supply handles, room for more drives, room for
added cards, energy star compliant.
• Motherboard - what processors can be
installed, memory speed, system buss speed, peripherals onboard and what
standards are they compliant to, BIOS
version and compliance to Microsoft.
• Processor - speed, Intel or AMD, side
buss speed, cache size, Hyper Thread Technology, MMX compliant.
• Memory - memory size, access speed,
manufacturer, EDO/EDD, parity.
• Hard disk - rotation speed, seek speed,
interface speed and type, capacity, number heads, manufacturer.
• CD drives - R or R/W, read speed, write
speed, DVD R or DVD R/W, interface speed.
• Floppy - internal or requires expensive
external one.
• USB - 1.0 or 2.0, multiplexed or independent ports.
• Video - motherboard integrated, plug-in, manufacturer, memory size,
DirectX compliant and a lot more.
• Ports - parallel ECP or EPP, serial, firewire 1394, 10/100 LAN,
audio.
• Software - manufacturer specific, what Microsoft drivers were
replaced by installed programs, are there any programs
which can not be removed, any manufacturer
Spyware
installed.
By
first determining what the PC must do, then a list can be made of what each
component must be capable of doing and what it must be compliant with. Then a final
PC selection can be made by looking at and comparing all the different
component specifications. Some times there will be situations where an off-the-shelf
PC does not meet all the user requirements and a PC needs to be custom
built and configured. There have been many LSI custom PCs built which cost less
and have more performance than it's closest off-the-shelf system.
Software can be an even more complicated issue where off-the-shelf PC manufacturers
have "added value" to their systems by incorporating their own programs or
trial and "limited edition" software to add market attractiveness and increase sales.
Some programs are great while others can cause problems later on down the
road. To explain better, the following list gives some examples of problems
customers have encountered. Manufacturer names have been omitted.
• Want to upgrade from XP Home to Pro but
the PC only allows their version for over $500 instead of store's $170.
• XP has a better faster CD
burner program but is overwritten by another burner program which can't be removed.
• The video driver is slow so my graphic
software is slow. Microsoft says the card is not compliant.
• PC has a built in medic program which
slows the system down by continually accessing my internet connection.
• XP isn't installed right and the PC only
allows their modified version of XP.
• PC dedicates a large portion of the hard
disk to crash recovery reducing available hard disk space.
• Removed some of the junk software and
now other programs don't work.
• Stuck with the
original slow CD drive because new
drives don't fit the case and the model is discontinued.
