What should I be doing to maintain my computer?


What I REALLY need to know is the basic, day-to-day regular preventive
maintenance, etc. that I should be performing on this equipment. Stuff that is
probably so basic to PC usage that no one has thought to tell me — what do I
need to know and DO to keep my computer trouble as well as virus free?

The virus-free part is addressed in my article
Internet Safety: How do I keep my computer safe on the internet?
I consider
that one of the most important articles here on Ask Leo!

But you raise a good issue – what other kinds of things should we be doing
to keep our systems running smooth?

First off, if you do nothing more than the steps outlined in
Internet Safety: How do I keep my computer safe on the internet?
probably about 80% there already.

In no particular order, here are few other things I think that every PC user
should consider doing on a regular, or semi-regular basis.

Windows Update: Setting aside malware, Windows Update is a
good place to visit for additional non-critical updates to your computer.
Updates often include bug fixes that, while not related to malware, can
sometimes manifest as crashes or annoyances if left unfixed. Related: How do I make sure that
Windows is up-to-date?

“… performing those steps on a regular basis can help keep your
computer running just a little faster, a little better, and perhaps a little

Backup: Something will break, and the contents of your
computer’s hard disk will *poof* disappear. You might be able to get
it back or you might not. Are you prepared for the “might not” case? Related

Defrag: I used to do this nightly, but now do it only once
a week. There’s nothing really wrong with never doing it, but on a seriously
defragmented drive you may notice a minor performance improvement if you do.

Delete Temporary Files: They have a tendency to accumulate
and eat up disk space. I don’t have a formal recommendation for how often to do
it. Personally, I do it when I remember or when my hard disk seems to be
running low on space. Maybe once a week or once a month or so. Related

Dust or Vacuum: Something that people overlook regular is
the accumulation of dirt and dust in and on their computer. Particularly for
those of us who are pet owners, it’s often easy for fur to accumulate inside the
computer and prevent it from cooling properly, thus shortening its life.

There are a few things missing from that list that others may consider

Ultimately your computer will for the most part run just fine even if you
ignore the all steps at the top of this article (except

critical). However performing those steps on a regular basis can help keep your

  1. CCleaner works for me and it is a great way of removing stubborn programs like Symantic security. I found using the config remove all programs failed to remove some of the Symantic files but ccleaner did it and it is free:-)

  2. When vacuuming the computer use the brush attachment not the straight hose. Once when cleaning the keyboard I thought “the brush works good, the hose will work even better”. Wrong!! It sucked some keys right off the keyboard. I had to dig through the dust bag for all the little parts and then spend an hour putting the keys back on the keyboard. Not fun!

  3. Hi
    I have been running the same win xp pro instalation now for the last three years , throughout hardware upgrades , even a new motherboard and xp is still running fine , never reinstaled , this is how i keep my pc in good order:
    1. antivir free edition runing 24/7
    2. sygate firewall on all the time
    3. winpatrol plus
    4. AVG antispyware gaurd running 24/7
    5. I run full virus check once a week
    6. I run Norton systemtools windoctor once a week
    7. I run Ad-aware once a week
    8. I make a new restorepoint once a day and keep 4 old ones on backup
    9. I run motherboard monitor 5 and sysmetrix to keep a eye on temperatures and other system actions
    10. I open my pc case once a month to clean the fans and blow dust out of system.
    11. I Run explorer proceses as seperate proceses
    12. My pc never gets switched of , only when i do upgrades or cleaning of components.
    13. My broadband conection is active 24/7

    I find win-xp pro to be the best os there is , I do run vista as well but just to learn the os as a second os on a seperate partition. but my xp – tweaked with x-setup pro and customised with style-xp , Yahoo widgets and a few others to make the system look and operate beter and more stable than vista. I never get crashes , mabe a lockup now and again due to unstable codecs , but rarely and no harm done.
    I never install any new software without first making a restorepoint.
    And last but not least i always read all the Ask Leo articles as i get the newsletter updates because there is very interesting articles.

    all for now
    Keep well

  4. Hi Leo,

    Thanks for sharing this helpful list. This is certianly helpful.

    I agree that it helps to follow some basic recommendations/best practices on keeping your computer healthy.

    One of my colleagues recently shared a similar helpful list of recommendations which could help your readers as well – so I thought I’d share it with you.

    Thanks again – nice work!

    Good luck!
