In the following sections, we'll try to come
up with some possible reasons for your slow PC. The best way to
proceed is to elimiante those which do not apply.
Remember, these are POSSIBLE roadblocks.
They're NOT BARRIERS. That said, I would highly suggest you
take the recommendations here to heart. Your problems will only
get worse as time goes by if you aren't willing to solve some
of these problems now. If you're confused at any point, or have
questions, please feel free to email me, and I'll do my best to provide
you with some guidance.
the last time your computer was
The first question I always ask is, when was
the last time you restart your computer. It's a good idea to
restart your machine, at least once every week or so.
Some people turn off the computer when
they're done with it. This is okay practice however it does
actually cause additional wear and tear to the power supply,
because it's a mechanical part in turning off and on frequently
can reduce its life span. Some would argue though that by
turning it off. The fan is running 24/7, which are smart and
less wear and tear on the power supply. Whichever you decide is
fine, but I recommend leaving on all the time, unless you go
away for an extended period of time.

may be able to tell you when you bought it.
Look on the back of you PC to determine if there
are any stickers indicating the date of install or
setup (some manufacturers use these for quality
Look up your computer's model number or one of it's
parts (like the video card) on the internet for
things like firmware revisions or the likes
When you purchased your computer, it likely came
with computer manuals and/or CDs, which may have a
copyright year on them
Worst case, you can always try and dig up the old
Chances are, if it's more than 4 or 5 years
old, this might explain why you're having troubles. There are
several of possible reasons:
you may have upgraded or installed a newer version
of some applications which require more memory than
your system supply, so the operating system is
constantly swapping to disk
it's likely that you haven't reinstalled or
restored Windows since you bought the PC, in which
case there's probably a lot of unnecessary clutter
on the box
your hard drive may need to be defragmented
you may not have enough free space on your hard
