Top 10 things you should be doing to maintain your computer

Written on April 29, 2008 by Melissa Hermanson

Everyone loves computers when they work. Everyone screams at them when they don't. Here's ten ways to keep your computer running smoothly into its old age. While I can't promise that these tips will keep your computer from ever having problems, it will at least help prevent them, and make recovery easier when they do occur.

1. Back up your data.

When was the last time that you backed up your data? Not 'when was the last time you thought about it', or 'when was the last time you told someone how important it is', but when was the last time you actually backed up your data? And how much will you lose if your current hard drive fails right now and you have to rely on that backup?

Think about that for a second. Now, go create a backup.

If you don't know how, don't have a regular plan, or just want to see what's new in the field, Consumer Reports has a good overview of the most common options. Personally, I have very little media on my computer, so I burn my files to CD once a year or so, and copy files to a flash drive in between. It's quick, inexpensive, and secure enough for my needs.

Another decent solution is to use a program like Foldershare to synchronise your files between two computers (even better, two locations).

If you have the opportunity, make a full disk image (a 'snapshot' of your entire hard drive) immediately after reloading the OS and all your programs. This gives you a clean starting point to go back to if you need to reload everything again, and will be much faster than redoing everything manually. Acronis True Image 11 is good for the job.

2. Clean dust from your computer.

Computers are some of the most efficient dust collectors known to man. Aside from looking gross and possibly being an allergy hazard, a dusty computer will trap heat, which can reduce its performance and lifespan. The easiest way to clean it is with compressed air - open up the case, take it outside, and blow the dust out. The exterior of the case can be wiped down with a damp cloth. Be careful about using household cleaners, as they can easily destroy circuit boards. For most computers, cleaning once every year or eighteen months should be adequate.

Beyond just getting the dust out, here are some other steps to consider: Dust often collects inside the CPU and video card heatsinks, consider disassembling and cleaning them if you're comfortable doing so, or at least using compressed air to specifically blow them out. While the case is open, plug in the computer and turn it on long enough to make sure all the fans are still spinning. Replace any that are dead or noisy (a common sign of a worn-out fan). If there is sticky residue or dirt on the circuit boards, it can be removed with a cotton swab dipped in rubbing alcohol, which will evaporate cleanly. (Make sure the computer is unplugged first!) If you're not comfortable with working inside your computer or suspect your computer has chronic overheating issues, Puget Systems or another professional repair service can help you out.

3. Clean up your cabling, and everything else too.

There are probably two things behind your computer: a mess of cables, and dust bunnies. If you're moving your computer, take the opportunity to clean your desk and floor as well. While I can't claim that a clean work area will improve your computer's performance or lifespan, it will certainly improve your peace of mind, and clean cabling will help prevent snags and stresses on your computer ports. If you have a lot of peripherals, consider using cable management of some type. Twist ties work fine, or make a trip to any large office supply store. You can use a full out cable solution, but even a five dollar cable wrap can neaten up your desk considerably.

  • While you're wiping down your desk, wipe down the monitor too. CRT screens can be cleaned with any mild glass cleaner, but LCD screens can't tolerate it. Use a dampened cloth or a product specifically made for LCD screens.

  • Keyboards can be turned upside down to dump out crumbs and dirt, or keys can be pried off and the whole assembly cleaned with compressed air. There are some good step-by-step guides available on Lifehacker. Take a picture first so you can put the keys back in the right place! If you're feeling adventurous (or just have a really disgusting keyboard), some people advocate running it through the dishwasher.

  • This is a good time to take a look at where your computer is located. Is there adequate ventilation? Is the computer out of direct sunlight, and away from heat sources? What is it plugged in to? There's no excuse for not having a good surge protector (not just a plastic power strip!), and battery backup units have become affordable for most users. This will affect the lifespan of your computer.

  • Smoking will make a mess of a computer faster than anything else I know of. While we at Puget Systems have never seen one quite this bad, we can always identify a smoker's computer as soon as we unbox it. Electronics absorb the smell very easily, and even an all-metal case will retain the odor after all the components have been removed. Plus, there's usually a layer of dust and tar on the circuitry that tends to be a giveaway as well. Please, if I can't convince you to quit smoking all together, at least take it somewhere away from the computer!

4. Organize your installation disks

Keep software, peripheral, and driver disks in a single location, preferably close to the computer. A shoebox works fine. Make sure you have them handy before attempting computer maintenance or repairs - it's amazing what can become necessary in the middle of a lengthy troubleshooting session, and it is common to not know what you're missing until you need it!

5. Run antivirus and spyware scans regularly.

This item should go without saying, but I'll say it anyway. Any computer that is connected to the internet needs to have some sort of antivirus software. There is a tremendous variety available, everything from AVG Free to enterprise-level solutions. Use whichever you like best. Most antivirus software will monitor the system for threats in real time, so a full daily scan probably isn't necessary, but do make time to run a full scan every month at the least.

Some antivirus programs also protect against adware and spyware, but not all. If yours doesn't, or if you just want an extra layer of security, AdAware and SpyBot are two of the best known (and free!) products available. While they may not be as destructive as viruses, adware and spyware will compromise privacy and slow your computer drastically. Run scans for them at the same time as your antivirus.

6. Clean up your software.

Every few months, look through the 'Add or Remove Programs' interface that is found in the control panel. If there's software on there that you don't use any more, remove it. This goes triple for browser toolbars, free games, and other resource-eating bits of fluff. Be a little cautious, though - some system drivers appear in this list, and can cause hardware to stop working if you remove them.

There's an excellent scanning utility on Steffen Gerlach's website that gives a graphical representation of the data stored on your hard drive. This will give you a good idea of just how much room your music collection really takes, or how much space is going to old games.

7. Clean up your OS

Windows is not the most efficient operating system, and sometimes needs attention itself. It saves a large amount of unnecessary information, mostly in the form of 'temporary' files (which never get deleted) lists of recently performed searches, and the like. There's an excellent program called CCleaner, which will clear out most of the unneeded data automatically. If you're interested in further optimizing your OS, there's a wealth of information available online, including an article on improving XP performance available here on Puget's website.

8. Update everything

Check for updates for your hardware and software. This includes running Windows Updates, checking for updated drivers, and checking for software patches. The easiest way to find these is to go to the manufacturer's website, to their support section, and then look for a 'downloads' section or search for your product's name. If you've been having problems with a piece of hardware or software, be sure to check for patches or updates - if other people have been having similar problems, it's likely the manufacturer has released a fix for it.

The exception to this is motherboard BIOS updates. Flashing a BIOS can be difficult, and if it's done incorrectly you may need to send the computer for professional repair to get it working again. If the update was specifically released to address problems that you've been dealing with, it's probably worth it. Follow the manufacturer's directions carefully! Otherwise, leave it alone.

9. Defragment

Once your hard drive has been cleaned up, it's a good time to defragment. This organizes your files, leading to faster disk access times and improved system performance. The Windows defragmenting tool (Start > All Programs > Accessories > System Tools > Disk Defragmenter) works well, or there's a list of open source and commercial defragmenting software available on Wikipedia if you'd rather use something else.

10. Read more articles like this one

Last but not least, continue to read articles like this one, and anything else computer related that catches your eye. The computer industry is constantly changing - even if you have the same computer, there will be innovations that affect you. At the very least, you'll go into your next computer purchase far better informed than you would be otherwise.

We at Puget Systems always encourage our customers to learn about computers in general and their system in particular. Well educated users tend to have fewer difficulties with their system, and besides, we love computers and think everyone else should too! Our commitment is to create a computer to meet your needs and budget, using our experience to assist you every step of the way from the first visit to our website to tech support calls two years later. We accomplish this in part through friendly sales and support reps, an informative website, and publishing articles on a regular basis. Give us a call or email, we'd love to hear from you!

11. Do not let your cat sit on top of your computer. Fur=bad.

I can't tell you how much cat hair I've blown out of systems over the last decade...

LOL! Even with our boxes up on the desk we still have to watch out for the cat hair!

I am in the turn the computer off camp but I think the bottom line on that is personal preference.

What are the thoughts on doing a fresh install of the OS every so often (year or so)?

What are the thoughts on doing a fresh install of the OS every so often (year or so)?

i only do a fresh install when i notice a problem or it seems to have slow down way to much havent had to do it much though

Posted on 2008-05-06 18:39:58

i only do a fresh install when i notice a problem or it seems to have slow down way to much havent had to do it much though

I reinstall my OS every 60-90 days, but that's because I do a lot of uninstalling and reinstalling...I do beta testing of applications and games, and installing different clients can make a big mess.

If you have a lot program errors, reinstall. If you're like me and leave a lot of file detrius behind, do it more frequently.

Posted on 2008-05-07 15:24:18

Sorry to revive an old thread, but I'd got a great alternative to that program by Steffen Gerlach's, called article.

@PC Heather:

Like you, I install/uninstall software quite frequently. To make matters worse, much of what I'm installing is beta or RC software with many sub-components. Here are a couple of things I do to make this process easier so that I don't have to re-format and reinstall everything all over again.

1. Set restore points before installing anything. It's so easy to just jump back to a restore point.

2. If your system is beefie enough, try using virtual machines. I set up a base XP SP 3 (with all patches and drivers) vitural machine to use as a base image template and then when I have to test anything I make a copy of that virtual machine and install whatever I'm testing. When I'm done with that piece of software, I just delete the .vhd file.

Be warned though that using virtual machines requires a good amount of RAM to dedicate to the image and each image will create a file that is, at a minimum about 13GB!

I agree with you and your suggestion can assist me to a great extent as your second point i like the most as you said
2. If your system is beefie enough, try using virtual machines now this chart will always be with me for safety of my computer

when my pets sit on my computer, it gets dirty and i dont bother clean it. when it breaks (because of too much dust) i let it rust away in the backyard and i go buy a new one (usually the most expensive one being sold at the time), then the cycle repeats, as long as i have pets, in which i love animals.

yeah all those tips are good they have worked wonders on my system over the past years.

12: Another one that works well is to actually turn it off at night when you go to bed. i can't count the times people ask me why there hard drive died when they leave it on for months on end IE:if your pc is not being used as a server it does not need to be on 24/7 they don''t take that long to boot anymore.

Posted on 2008-04-28 18:04:37

I'm not trying to start a Flame but....
I have to disagree with turning your computer off. (I have 10 computers) 3 of which are now Puget Systems computers :-)
I leave all my systems on 24/7 unless a thunder storm is coming then they go off. I have one system that is running Windows 3.1 and it's still working, I also have another that I run 98 on and that is still working as well. Ok one system is an Apple so maybe we shouldn't count that because they are just way more stable the Microcrap based ones.
I have a few others that I have made a habit of turning off at night and I have also found that I have replaced the power supplies in them often.
Maybe you should set your computer to turn off non working items such as Monitor/HD ect... in the power scheme but as I said I have to disagree with powering all the way down just for the sake of powering down. The 3 systems I have from Puget are on 24/7 and no problems.

Posted on 2008-05-02 20:37:56

In my opinion, there are good arguments for and against:

Why you SHOULD turn it off:

1) Power savings
2) Possible longer component life (debatable)
3) Quieter!
4) Less dust buildup (no airflow = nothing to suck the dust in)

Why you SHOULDN'T turn it off:

1) Heat up / cool down cycles shorten component life
2) Turning components on and off can lead to failure (added stress during power up)
3) More hassle

Myself, I set my monitors to go into standby after 20 minutes, and my hard drives to power down after an hour. That way I get a good part of the power savings and additional quiet, but not as many of the downsides.

Even devices in standby draw power though -- so if I am out of town for even just the weekend, I do completely power off the computer (including turning off the power strip).

Sometimes I need to remote control my computer, which makes the decisions a little more complicated too :) But I have my work computer set up for remote control as well, and I mirror my documents between home and work, so in general I treat my work computer as the one always available for remote control.

i let my computer run 24/7 so my pets can be warm as they sit on my computer all the time, and when the old one breaks, i toss it in my garage (literally, toss) and let it rust away. I just buy a new one the next day, so the cycle can repeat.

Posted on 2017-11-10 05:25:23

yeah it's is good to set the drives to turn off after a certain amount of time, i was refering to the average computer user that don't know about that feature and leaves them running along with the monitor maybe in a screensaver. sorry for misconceptions. it could also come down to if your components are good quality like your pugets they have great hardware and where built very well most oem factory pc's like dells,hp's and others are made quickly with cheaper components all these things factor into it also. granted some pc's from corps are great and well designed just not all of them. i think older ones were made better even just like almost everything else lol.

Posted on 2008-05-04 06:07:40

That looks interesting. I've always been a "pie chart" kind of guy myself, but I think I could get used to it, and you see a lot more at a glance with that program.

Wow, I love this post though it's a bit old. If I may add a suggestion, refrain from putting food or drinks near your unit or the ants may attack it. My friend's unit had a fatal crash only to find out hundreds of ants inside his laptop.

Posted on 2020-08-31 02:14:58

I can't recall if we've had an updated article in quite this same vein or not, but I do think some of the advice here is pretty timeless. The first three especially - backing up data, cleaning the inside of the computer, and keeping your cabling tidy - are all excellent and will be applicable as long as tower PCs are a thing :)

I'll ping our support folks and see if someone there wants to write an updated post on this topic as well.

It's good to know that to maintain a computer, it's important to run the antivirus software monthly. My husband and I are thinking of opening a computer shop in town to help students without any PC at home. We would need to have the computers maintained properly, so it would be wise to hire an IT support service. Thanks. https://www.businesspcsuppo...

Your Way Of Explanation was good. You add some valuable points. Here I am sharing some information about hardware and networking.Hardware and networking training plays a very important role in being a professional in that field Most of the companies looking for professionals who can handle their networking department or the networking requirements very efficiently. For that kind of professionals in hardware and networking and also if you want to grow your career you should surely think to forgo a hardware and networking training course. To provide the maximum performance for their use is the basic purpose of hardware and networking.For Internet to work properly we need proper Hardwares. Inorder to maintain those Hardwares we need proper connectivity. Thats where Networking comes into picture. For all these things to work we need technicians and engineers.Therefore, if you are looking for a top hardware and networking training in hyderabad amongst these, it is highly recommended to see if the training facilitator which you will be opting for, is well associated and experienced with hardware and networking.
