Why Is My Computer Slow?

Windows computing systems tend to
get slower and slower as time goes along. Why is that? Based on my own
experience, I've compiled the following list of major performance
issues, roughly in the
order of frequency:
- Accumulation
of garbageware and poorly tuned software is the leading cause of poor
performance. Garbageware includes a constellation of
programs, services, and tasks that run in the background, pointlessly
and uselessly consuming memory and CPU resources. Right out of the
gate, consumer-class systems come massively overloaded with
garbageware, which hardware vendors are paid to install by garbageware
vendors. Sony even has the audacity to offer systems without
garbageware for an extra
$50.00!
Interestingly enough, business-class systems do not come loaded with
garbageware, meaning PC vendors are quite happy to willingly cripple
brand new consumer systems.
Also, as time goes along, garbageware is
concurrently installed almost every time you install other software,
such as a printer driver disk, a broadband installation disk (unneeded)
or free software such as itunes, Adobe Reader, Java, and many others.
Vista has it's own special performance issues, namely a whole pile of
built-in garbageware tasks that continuously and uselessly grind your
hard drive in
the background. In fact, Vista will come to be known as the
great hard drive
destroyer because hard drives, particularly laptop drives,
more or less fail proportionately to the amount of use they
get.
The solution to garbageware is to remove or disable unnecessary
software.
Unfortunately, this usually takes an expert to do, as it is
often difficult to determine which software is needed and which
software is superfluous. Additionally, some software should be removed,
whereas it's best to simply disable other software rather than to
completely uninstall it.
- Insufficient
RAM, particularly in conjunction with Item 1, will really wreck system
performance. Most vendors skimp on RAM on consumer-class systems, even
though this is an inexpensive component, and by far the most cost
effective means for improving performance. Just out of the
box, a system may perform barely acceptably, but one or two
unknowing garbageware installations later, system
performance can tank. Even with garbageware removed, adding RAM is a
big
win for RAM-starved systems.. Windows XP performs best with at least 1
GB RAM, and Windows Vista
needs a minimum of 2 GB RAM. On new systems that use PC5300 memory, the
cost of a 2 GB RAM kit is $30.00 for good name-brand memory!
- Bloated
all-in-one security systems like Norton and McAfee products
consume tremendous amounts of memory and CPU resources. Even worse,
they are ineffective against modern malware, and worst of all, they are
annoying and frequently cause awful system behavior problems, like
silently blocking access to some or all of the Internet. There are
free, lightweight, non-annoying alternatives that are more effective
than Norton and McAfee products.
- A failing
hard drive can kill system performance. Hard drives degrade over
time, causing the drive to silently retry accessing failing sectors
repeatedly, as well as using up the limited number of spare sectors
available for reassigning to bad sectors. Unfortunately, Windows makes
this failure process completely opaque to the user, and by the time the
first (obscure) drive failure messages begin showing up in the
system events
log, the hard drive is on the verge of crashing. Aside from slowed
performance, the first symptom of a failing hard drive is often the
crash itself. Even more unfortunately, it doesn't have to be
this way since hard drives maintain onboard health statistics that
Windows ignores. However, third-party tools can be used to read these
statistics and determine whether a hard drive should be replaced.
- Malware
infections usually create obvious havoc with both performance and
usability. However, sometimes malware infections have no other symptom
except awful system performance. With the proper tools, malware can be
successfully removed at least 90% of the time, though sometimes malware
leaves behind residual system damage that must be manually repaired.
- Once
a hard drive is 85% to 90% full, performance will really tank as the
system struggles to find contiguous areas big enough to write new data
files on. The hunt for unused areas also works the hard drive much
harder than normal and can eventually cause the drive to fail
prematurely. The solution is to replace the old hard drive with a
new drive that has larger
capacity, first cloning the old driver onto the new drive.
- Performance
can sometimes be improved if the hard
drive desperately needs to be defragmented. Defragging the hard drive
once or twice a year is usually sufficient. However,
sometimes heavy, continuous system usage requires defragmenting more
often.
