Computer Repair Issues: All-in-One Desktop PC Repair and Maintenance

All-in-One Desktop PCThe PC repair realm has a new challenge.  All-in-One desktops are now all the rage.  These are the type of computers that have the CPU and screen in one single unit.  In other words, there is no separate tower.  This is a real space saving and convenient design.  MAC desktops took this form years ago, and now Windows desktops are following suit.

There is one drawback to having this type of unit however.  Maintenance and the cost of repair.  The main issue is heat, which wears down components or burns them out.  They really cram lots of components into a small space, so they tend to run hot.   These units are basically laptops on a stand, with the LCD screen attached, so they are more expensive to repair, just like laptops are.

They tried making these PC’s several years ago, but it was a disaster because back then, processors chips and hard drives ran very hot.  It’s a lot better now with the lower voltage, cooler running components, so it’s a better unit overall.  Still, you have to be careful.  Here’s some tips to help you.

1) Keep the unit in a well ventilated area, so it can get air to pass through it freely.  Keep the surrounding area free of dust, so it doesn’t get into the vents and clog things up.  If the PC will be in a dusty area, like a workshop, don’t get one in the first place.

2) Don’t run too many programs at the same time, or run heavy duty applications, like video editing or high-end games.  This works the PC very hard and generates lots of heat.

3) Check your start-up programs and any other background programs that may be running.  If too many are running, this works the PC harder and generates more heat.  If you know how to check for these, by all means do it.  If not, take your unit to a computer repair technician and have them tweak and tune up the PC so it runs less background programs.

Feel free to buy one of these types of computers if you like, but just keep the above tips in mind.  Do not buy one if you’re a heavy gamer or if you work your computers really hard.  They’re not designed for that type of use.  If you’re a casual user that mostly uses the internet and email, these units are just fine.

I hope this helped you.  If you need any more information or have more PC Repair needs or questions, please see the Saguaro PC Tech website for our conntact information.  Thank you.

Free PC Diagnostics: Confusion and the Truth

You see free diagnostics advertised everywhere. This subject needs lots of clarifying. It’s a touchy subject that angers both customers and computer repair shops alike. I’m no exception.

First, lets address the confusion. What exactly is a diagnostic?

… Is it a quick look at your PC and an educated guess?
… Is it a thorough testing of all your hardware and software?
… Is it a thorough troubleshooting and testing service?

The answer is yes to all of these. Therefore the question becomes, what can you expect for free? Do you really expect a repair shop to spend hours working on your PC for free? Do you think they can survive if they do this? Let me ask you this… do you work for free? What would happen if you did? Could you survive?

Now that we’ve cleared this up, let’s ask “What is a Free Diagnostic?” It is one of two things:

1) A “Bait and Switch” scheme to get you into the store
2) A quick look at your PC to get a general idea of the problem, i.e. a quick consultation.

Any honest repair shop will take a quick 10 – 20 minute look at the problem, or even do a simple repair for free, but that is all. However, some computer problems are complex to the point that even an experienced technician will not know what the problem is unless he or she does some in depth troubleshooting. That is not free, nor should it be.

Honest shops will not charge for all their time in these more complex cases if you decide not to do the repair, but they will charge a small diagnostic fee, usually somewhere between $30 to $60 (more for laptops). They still lose money, but at least they get something for their time.

The dishonest shops will pretend they did a diagnostic and then make up a story to get you to do an expensive repair, like replacing a hard drive, motherboard, or reinstalling Windows. This is also what usually happens with Big Box stores (including Office Supply stores). They also use this method to sell you a whole new computer.

In closing, a Word of Caution:

Do not pressure a repair shop to do a free diagnostic. If you do, they’ll either turn down the job and send you away, or recommend a major repair. They can’t spend the time to do a thorough diagnosis unpaid, and will recommend a broad range (i.e. major) repair to cover all the bases, which will definitely fix your computer.

If you’re fair to them, you may get out with a $100 repair. If not, it may be $400. This is more survival behavior than dishonesty (yes, I know it’s a fine line). They have bills to pay, and a need for food, clothing and shelter, just like you.

Laptop Repair: Overheating Issues

Does your laptop shut down on its own?  Does it get so hot you can’t keep it on your lap?  Does the fan scream or make grinding noises so loud it scares you?  If so, you could be having overheating issues.

What’s happening here?  First of all, if the processor (CPU) gets too hot, the laptop will shut itself down to protect it from burning out.  There are other reasons for unexpected shutdowns, but this is a major one.  This can also happen if the video (graphics) chip overheats.

This could happen for several reasons, but the major causes are as follows.

The fan is clogged or is going bad: 

It could be gunked up with dust or pet hair, preventing the air flow of the fan.  Sometimes the bearings on the fan go bad, resulting in grinding noises.  Dust and hair can either damage the bearings directly, or block the fan from rotating freely, which in turn can damage the bearings.

The Thermal Compound on the CPU has dried up and/or cracked:

In this case, the laptop will shut down on its own, or the fan will run really fast.  Why?  There is a thin film of heat conducting “grease” that sits between the CPU itself and the surface of a metal plate called the “Heat Sink”.  It’s like a radiator and has thin metal (usually copper) fins to help dissipate the heat from the CPU.

The thermal compound forms a seal that ensures full contact between the CPU and the heatsink, so that it efficiently pulls off the heat.  Over time, it can dry up and crack, breaking that seal.  Old, dried up compound also loses it’s ability to transfer (pull off) heat from the CPU.

Repair & Maintenance Options:

1. Get a can of air and blow it into the cooling vents of the laptop.  You’ll be surprised at what comes out.  If you wait too long however, there may be so much caked up in there, this won’t help.  The laptop may have to be opened up, so a technician can get in there and clean it up.

2. Broken fans have to be replaced.  This is not usually a big job, and the fans are cheap.  On some models however, the fan and heat sink are an integrated assembly and you have to replace the whole cooling system.  This is a bit more expensive, but still not too bad.

3. Remove the old thermal compound and put on a fresh layer.  This costs a little more, as you have to remove both the heat sink and fan, so you can get to the CPU.  When we do this, we use a higher quality compound than what the laptop came with.  We use a silver-impregnated compound that makes the laptop run up to 10 degrees cooler than standard ceramic compounds.

Online PC Tuneup Sites – Most are Useless or Even Scams

What’s the deal with these sites that promise to double your PC’s speed with just the click of a button?  Yes, we all hear the commercials where someone is ecstatically happy because his or her PC is running “faster than ever”.  Oh really?

You may think I’m posting this because I’m a repair technician and get angry when I hear these.  Well you’re right, but not because I’m afraid of the competition.  I’m angry because these claims are mostly scams that take advantage of people.  You can speed up your PC by downloading any of a wide selection of free utilities, versus paying these bozos.

Now I’m only talking about very basic cleanup processes on PC’s that are basically in good shape, because that’s all that these sites or the free utilities can handle.  A badly under-performing PC that locks up and freezes, or gets Windows errors cannot be fixed like this.  These sites dupe people into thinking they will, and that angers me even more.  Then, they start charging extra fees for more extensive procedures.

Why not Clean Your PC Yourself, for Free?

I recommend a great little free program called “C-Cleaner“.  It’s very popular among PC Technicians and is part of our arsenal of standard tools.  You can download it from the “Resources” tab on our Saguaro PC Tech website, or at Download.com.  There’s a paid version too, but you don’t need it.

To clean and tune a really slow PC suffering from lockups and errors, several procedures are required, including checking for viruses and spyware, checking the health of the hard drive, removing outdated programs, installing Windows and driver updates, etc.  The list goes on.

Again, these sites will charge for more work, but many of these procedures can’t be done very well, or even at all via on line support.  Don’t waste your time or money.  You may find that taking your PC to a reputable local repair shop will be both cheaper and more effective.

Laptop Repair: Liquid Spills on Keyboard

What should you do if you spill liquid on your laptop’s keyboard?  How can the damage be repaired?  What’s the possible extent of the damage?  These are common occurrences unfortunately.  We can repair laptop liquid spill damage, but the seriousness of the damage and the needed repairs depend largely on what you do when it happens.

Possible Extent of Liquid Damage:

I’ll just describe the worst-case scenario.  This would be if the liquid goes through the keyboard and into the the deeper parts of the laptop.  It can short out any of the internal components, including the motherboard (or logic board).

Even if it dries and works for a while, if the liquid was anything other than water, it can corrode the electronics and the machine could die later on.  This is why I always recommend letting a technician look at it.  The damage can get worse over time, thus costing more to repair if you wait.

Emergency Procedure:  If you spill liquid on your laptop, do this immediately:

  1. Close the lid and turn the laptop upside down. This prevents the liquid from seeping too far into the laptop.
  2. Unplug the power and remove the battery. Cutting off all power prevents short circuit electrical damage.

Don’t worry that this will cause an improper shutdown.  It’s better than ruining the machine and occasional improper shutdowns are not a big deal.

Leave the laptop this way and let the liquid seep out of the keyboard.  If the spill was just water, let it dry out for several hours or overnight.  When you get home, you can open up the lid, but leave the laptop upside down, perhaps propped up against something so you don’t damage the screen.  When it dries, turn it on.  If it works… cool!  If not, bring it to a repair shop.

If the spill was not water, bring the laptop to local PC Repair Shop.  I mean a real repair shop, not a big box store, as they’re clueless.  If you’re adept and adventurous, you can try to do more, but I strongly advise against it.  I’ve seen people mess things up pretty bad when they tried.  Still, if you insist, try the following.

Get an Electronic Cleaning Solvent…. Do Not Use a Household Cleaner!  You can pick up these special solvents at an electronics store.  I don’t mean an Ace Hardware either.  I mean a real electronics store.

If you’re not up to removing the keyboard, get the solvent in a spray can so you can get it into the keyboard while keeping it upside down.  If you do remove the keyboard, you can soak it in a tray of solvent.  Inspect the area under the keyboard and see if the liquid got in deeper.  If so, stop and bring it to a repair shop.

In closing, don’t try this yourself, but if you do, be careful!  Some of these repairs are difficult.  It’s not always apparent which component was damaged, so we often have to test everything.  Give us a call and we’ll do everything we can to save your laptop.

Laptop Repair Issue: Deciding on New or Used Parts

If you need parts for a broken laptop repair, an important choice to make is, should you get new or used/refurbished parts?  Here’s my thoughts and policy that I use in my repair business.

I’m talking about major components here, like motherboards and LCD screens.  Other minor parts are no big deal, as they’re not expensive.  For these major parts, the difference in cost between new and used/refurbished can be as high as $100 for LCD’s and $150 for motherboards.

If your laptop is over 3 years old, you’re better off with used or refurbished parts, unless it’s a high-end model (e.g. if it was over $1000 new).  If your laptop was a basic model with only a year or two of life left in it, you want to keep your repair cost low.

If your baby is a high-end beauty that still runs fast and is pretty up to date, you want to stick with new parts, as they are more reliable and will give your laptop longer life.  You want a good machine to last a while, since you spent a lot to buy it in the first place.

For newer laptops (less than 2 years old), you want to stick with new parts.  You want your machine to last 4 or 5 years, so you want the longer life and reliability of a new part.  Of course, if your laptop was a budget unit you bought for $299, it’s probably not worth doing a major repair.

What other considerations are there in choosing new versus used, or even in doing the repair it at all?  This is a cost/benefit decision.  If the cost of the repair (including labor) is half the cost or less of buying a new unit, you should definitely repair it.  If you can do this with new parts, go for it!

Most of these major repairs cost $300-$500 using new parts, or $200-$350 with used parts.  A good, solid mid-range laptop these days goes for $600-$800.  So you can see it’s a close decision.  If you bring your laptop to us, we’ll advise you on what’s best to do.

Extending Your Computer’s Life: If Your PC is over 3 Years Old

I often hear the question from my customers, “My Computer is getting old.  What do you recommend I do if I can’t afford to buy a new one?”  Here’s what’s happening and what you can do.

The major issues that deteriorate the performance of older computers are:

1) Insufficient Memory (RAM):

Machines that are in the 3-5 year range of life have low amounts of RAM by today’s standards.  This is because as time goes by, all those Windows updates you’ve been getting have actually made Windows bigger, thus needing more RAM.

You may also have installed new software (programs) over time.  Newer software has more features, and so is often larger than older programs, thus needing more RAM.

2) The Hard Drive:

This is the storage device inside your computer.  It is a mechanical device and like any mechanical device, the more usage you place on it, the more it wears down.  It can become increasingly inaccurate as it reads and writes data, thus causing file corruption, data loss and a slowing down of its operation.  What can you do?

Defragment Your Hard Drive! This will make your hard drive last much longer and help your machine run faster.  Why?…. Over time, the data on your hard disk gets fragmented and spread out all over the disk.  This means the drive has to look all over the place to get your files and has to work much harder, stressing and slowing it down.

All versions of Windows have a built-in defragmenting utility, but in my professional opinion, 3rd party “Defraggers” do a better job.  I like the free “Defraggler” program, made by Piriform Software.

What if this doesn’t help? Then it may be a good time to replace the hard drive.  This gives you multiple benefits.  The most important preserving your data.  If you wait until it fails, you will lose your data, such as your pictures, documents, emails, address books and videos.

The second benefit is performance.  With a new hard disk, you have the chance to reinstall or upgrade your Windows to a newer version.  A fresh installation of Windows gives you a huge increase in performance.  Your PC will “run like new”.  Also, the newer hard drives are faster than older ones, giving you a further boost in speed.

3) Old Software and File Buildup (junk files):

A lot of the software that came with your PC is outdated and is taking up space.  You may also have lots of programs running in the background that you’re not even aware of.  Some of these programs came bundled with programs that you downloaded, but piggybacked themselves into the download and installed themselves without your knowledge.  The biggest culprits here are Toolbars (Bing, Google, Yahoo, Ask, etc.).  You should uninstall these unneeded programs, but be careful, if you’re not sure, don’t touch it.  Call a professional computer technician.

Finally, there are many files that get created automatically in the background by the programs you’re running.  These are only temporarily needed, but are left behind even after they’re no longer needed.  Clearing these out with a good cleanup utility, like “C-Cleaner” can help regain performance.  This free utility is also from Piriform Software, the same people that make “Defraggler”.

So there you have the basics.  The two utilities we mentioned can be a great help.  You can find these on our website’s links page, or at CNet’s Download.com site.

Antivirus and Security Software Ratings: Who’s the Best?

As the owner and operator of a computer repair company, I have tried them all.  Over the years, things have changed with Antivirus software, but some have consistently rated very well year after year.

Believe it or not, some of the best Antivirus products out there are free.  Why?  It’s because these are lesser-known companies, usually European, who are trying to break into the US market.  They know that technicians will recommend them because of their superior performance, but customers may not want to change their software because they just purchased or renewed a subscription to their current software.  However if the change is free, they will usually go with the technician’s recommendation.

Eventually they hope the customer will buy the full version of the program, which has more features, better protection, plus no more prompts to upgrade to the full version.  Still, the free versions do a very good job and most of our customers have stayed with the free versions for several years.  If you are an average user, are not very adventurous in the types of websites you go to, and don’t have kids, the free versions are good enough.

Of course, no Antivirus or Security program can give you 100% protection.  The virus and spyware writers change their code so fast, that the Antivirus companies can’t keep up.  Sure, they may update their software several times a day but still, some infections do make it through.  The best you can hope for is that your software will block 97–98 percent of the infections.  This usually translates to years of virus-free computing for most people.  So essentially, the best programs will protect you, but just know that there will always be a slight chance that an infection may get through.

Just so you know, all of today’s Antivirus programs also provide Anti-Spyware and Anti-Malware protection as well, so you covered from these other threats tool.  Actually these days, most of the infections we see are Spyware (or Malware)

So what software products to we recommend?  Our favorite free programs are:

1)      AVG Antivirus

2)      Avast Antivirus

3)      Avira Antivir

Among the paid programs, we recommend getting the full security products, which add firewalls, anti-spam and parental controls to the basic antivirus protection.  If you’re going to pay, you might as well get full protection.  Our favorites are:

1)      Norton (Symantec) Internet Security 2010

2)      ESET NOD32 Smart Security 4.0

3)      Avast Professional

4)      Avira Premium Security Suite 2010

5)      Kaspersky Internet Security 2010

6)      PC Tools Internet Security 2010

Finally, we recommend getting a standalone Anti-Spyware/Anti-Malware program as well, since these types of threats are the most prevalent today.  Standalone Anti-Spyware programs generally do a better job because they are totally focused on these types of infections.

Unlike the free Antivirus products, the free Anti-Spyware programs do not run full-time in the background or automatically update.  You need to manually run them, update them and scan once a week.  Again, for the average user, this is fine.  If not, get the full versions.

The nice thing about these is that you can run them alongside your Antivirus program.  On that note, you should know that you cannot have more than one Antivirus program on your machine.  They will conflict with each other and your protection will be compromised.

Our recommendations are:

1)      MalwareByte’s Anti-Malware

2)      Ad-Aware Anti-Malware

3)      PC Tools Threat Fire

You can find all these programs at the popular website Download.com.  For more information, please visit our website.

Good luck and happy, clean computing.
