Computer Beep Codes: What do They Mean?

Have you ever noticed that when a computer is turned on there is a single quick beep before you see the screen load?  There is a reason for this other than knowing the computer is on.  It is to let you know that all the functions of the Power On Self Test passed or POST.  In the BIOS of the computer’s motherboard there are many different things that need to be recognized before the computer will will function as a whole such as the CPU, Hard Drive, Video Card, and more.  When a computer sounds off more than one beep or a series of long and short beeps, then that means there is something wrong with the hardware.  Below is a generic general translation of the beep codes.

No Beep:

• There is likely a short circuit, no power, or possibly loose cards/peripherals.

One Beep:

• All is well, nothing to worry about.

Two Beeps:

• There is an error in the BIOS/CMOS.  This will depend on the error message on screen, as to what it is yelling at you for.

One Long Beep and One Short Beep:

• There is a problem on the motherboard.  This can be related to blown or failing capacitors.

Two Short (Sometimes three Short):

• Video Card:  If you card is on-board, you may need to replace the motherboard unless there is a slot for a card to be installed.  If you have a video card, try re-seating the card or cleaning out any dust around the slot before re-seating.  Otherwise, it just likely you have a failed/broken video card.

Three Long Beeps:

• Keyboard Error:  Check for stuck keys, or altogether just replace the keyboard.

Repeated Long Beeps:

• Memory Error:  Memory has died or is failing.  Replace with new memory.

Continuous H-Lo Beeps (Sounds Like a Siren):

• Computer Processor Unit is over heating or heated.  Turn system off immediately.  Check thermal compound between CPU and heat-sink, apply new if needed.  Check the fan on the heat-sink to be sure it is spinning.  This can be done after the computer has cooled down for at least 30 minutes.  Briefly turn system on, and see if the fan is running and then turn it back off.

Remember, not all beeps are the same.  They can very from manufacturer to manufacturer.  Checking with your manufacturer’s motherboard manual may be a little more descriptive if the beep error code isn’t listed above.

PC Email Errors

In this article, we will discuss the following topics:

•  The name and purpose of three common file types associated with e-mail client programs,     such as Microsoft Outlook.

•  Steps to resolve common file type errors.

Common e-mail file types

.nk2 file extension and its purpose

An .nk2 file is commonly referred to as Outlook’s AutoComplete file. Outlook is a popular e-mail program from Microsoft. The .nk2 file format was first introduced with Outlook 2002 and since then has become an important component of the Outlook application.

The .nk2 file is used by Outlook to store details about the e-mail addresses to which you have sent e-mails. Outlook’s AutoComplete feature works in conjunction with the .nk2 file to help a user when he/she types an e-mail address or recipient’s name in the To, Cc, or Bcc field. For instance, when you type a letter, say ‘a’ in the To field, the AutoComplete feature refers the information stored in the .nk2 file and displays all the e-mail addresses starting with the letter ‘a’ to which you have previously sent an e-mail.

.idx file extension and its purpose

.idx files are index files that are used by various applications, including Microsoft Outlook Express. The .idx files store an index of mail messages and are used when you import old Outlook Express mailbox into Outlook Express version 5 or later.

.nick file extension and its purpose

A .nick file is commonly referred to as an Outlook 2000 Nickname file and these files allow you to designate a string of characters as a nickname of an e-mail address.

Resolve file type errors

In case you receive an error, such as ‘Windows cannot open the file’ when you try to open a file, then either the program required to open the file is not present on your system or the file in question is corrupt.

To fix the issue, you need to identify the program with which the file opens and install it on your computer. If the error persists or you already had the required program, then we recommend you use a reliable file extension repair program to help you open the desired file.

In case the file type error occurred while opening an application then plausible causes include: a poorly installed application, malware infection or registry errors. To fix the error in such cases, perform the following steps:

Step #1 – Uninstall and re-install the program with which you are receiving the error

Using the built-in Add or Remove programs utility, uninstall the application that is generating the error and reinstall it. If the error persists, move to the next step.

Step #2 – Perform a malware scan

Update your security software with the latest malware definitions and security updates and run a malware scan on your entire computer. To ensure all residing threats are aptly removed, you may run the malware scan twice.

Step #3 – Perform a registry scan

Using a professional registry cleaning software, perform a registry scan to fix registry errors and restore the integrity of the data stored in your registry.

Common File Extension Errors And How To Resolve Them

Is your computer screen flooded with a myriad of file error messages?

Are you unable to open a particular file on your computer?

Are you unable to launch an application because one or more application files are either missing or corrupt?

If you answered YES to any or all of the above questions, then what you require is not a computer expert’s help but the simple steps provided in this article to get rid of your computer woes.

Errors related to different types of file extensions such as the .pgm file extension, .asp file extension, and the .ex_file extension can cause great discomfort by preventing you from opening/editing/saving/converting an important file. Further, file extension errors may prevent you from launching the software to which the faulty file is a part of. The comfort comes from the fact that file extension errors can by easily resolved.

The purpose of this tutorial is to equip the average Windows user with the means to tackle irritating file extension errors on their own.

Perform the following 3 steps to troubleshoot file extension errors:

•  Use a file extension repair software – If you are unable to open a particular file then it is recommended that you seek the services of a reliable file extension repair tool. These tools are quite easy to use and facilitate easy opening of various file types by fixing the file ‘openers’ on your Windows computer.

•  Run a malware scan – If the file extension error is of a serious nature, for instance if the error message hints that one or more files are corrupt or damaged, then it will be prudent to run a thorough malware scan.

Malware programs are notorious for corrupting and deleting essential files and causing various errors, including file extension errors. The remedy in such a case is simple. Restart Windows in Safe Mode and perform a thorough malware scan. The steps illustrated below show you how to restart Windows in Safe Mode.

1. Quit all the running programs and restart your computer.

2. As Window reloads, press and hold the F8 key.

3. Select the Safe Mode option in the Windows Advanced Options Menu, using the arrow keys and press Enter.

After you have quarantined or deleted all reported threats, do not make the mistake of lowering your guard. In the future, prevent re-infection by regularly updating your security tool and scheduling regular malware scans.

Clean your registry – Although this point is mentioned last, do not let that dilute the importance of a clean registry.

Did you know that the majority of file errors occur due to incorrect file associations?  Yes, that is right. And errors in the registry are the biggest cause of incorrect file associations on Windows computers.

The solution is fairly straightforward – use a reliable registry cleaning tool to clean your registry. You will be pleasantly surprised to find out how easy it is to clean your Window registry and perform other registry maintenance tasks with the help of a good registry cleaning tool.  All you need to do is click your mouse a few times. The benefits of a clean registry are aplenty – the most noticeable benefits include faster computer speed and the disappearance of errors, such as file extension errors.

Perform the above 3 simple steps to get rid of file extension errors for good and enhance your computing experience.

Computer Fans and Their Importance: Cooling a Computer

Probably the most overlooked component inside of any computer (laptops and desktops alike) are the fans.  These devices are very inexpensive, however if they fail can lead to a very expensive repair.  In this article we will cover what computer fans are, their function, and some general maintenance that should be done.

Purpose of a Fan:

The primary purpose of a computer fan is to keep a computer cool.  CPU’s and other chips inside the computer can become very hot, in fact hot enough to fry an egg or even hotter.  So keeping the air flowing is critical, unless the system uses a liquid based cooling system (we will not be discussing liquid cooling in this article.)

Types of Fans:

•  Power Supply:  Most PSU’s (Power Supply Unit) come with one 90mm or 120mm internal fan, however some power supplies (recommend) have two, one intake and one out-take.  It is very important to keep a power supply cool as it will prolong the life of the power supply.  A power supply that needs this type of cooling that does not have an operating fan can reduce it’s life significantly, because it will only be a matter of time before things get too hot inside that little box for components to melt or even explode due to heat.

•  CPU (Central Processing Unit):  It is very critical to have a well working and operating fan on this component.  Most modern CPU’s range from 35 degrees Celsius to 75 degrees Celsius (or 95F to 167F.)  So, keeping the heat moving off the heat sink is essential.  Never let a CPU go without an operating fan that a heat sink requires.  Most CPU thresholds are 80 degrees Celsius before physical failure begins, which can further damage a motherboard and connected components.

•  Chipset:  Some motherboard chipsets come with fans and others have passive heat-pipes.  I prefer the passive heat-pipes over fans, however don’t be fooled by the importance of these tiny little fans.  When they fail, the most common problem that arrives is system halt blue screens or also known as the blue screen of death (BSOD).  The system chipset needs to stay cool just as much as the CPU does, period.

•  GPU (Graphic Processing Unit):  These fans can be found on the medium to upper end video cards.  Much like the CPU Fan, all the above applies.  If you want to keep your games running smooth without artifacts and other anomalies, then keep your video card chilled as much as possible.

•  Case (chassis) Fans:  Not all system setups need or come with case fans, but I would never recommend it.  Relying on your systems power supply to cool the inside temperature of the case is not going to work effectively. Case fans can come in all different sizes varying on the style of case.  Having a minimum intake and out-take fan in place will make a big difference in your setup as long as the room temperature is less then the temperature inside the computer.

•  There are other supplemental fans that can be installed such as hard drive, CD style (front of case), and PCI slot (great for helping CPU’s and video cards.  These fans are typically more optional and not mandatory than the above fans, but will add some degrees in differences.  Every degree counts inside of a computer.

Because of dust, animal hair, cigarette smoke, factory air, etc. fans aren’t entirely maintenance free.  Depending on the environment, will depend on how often you clean the fans and alike components.  Be sure to stop by our “How to Keep a Computer or Laptop Dust Free” page for preventative maintenance and cleaning tips.  Fans are typically rated between 50,000 to 80,000 hours (that’s between 5 1/2 years to 9 years of continuous use.)  While this number almost rarely is achieved because of environmental variables such as the above, it isn’t too far off if they are well maintained.  Unfortunately fans will fail before their time.

Replacement:

When replacing fans, be sure to replace with a good brand and a quite one.  We recommend Vantech Stealth Series fans.  They are very quite and run up-to 3,000 rpm’s.  They don’t sound like jets taking off in other words.  However when you need more air flow, you will have to sacrifice some noise.  Gaming rigs need this kind of air, so noise reduction will become a challenge with fans in the mix, unless you go with liquid based cooling.  Don’t forget if you are adding more fans than your system originally had, be sure your power supply has enough output to supply for the additions.

Cleaning Screens: Right & Wrong Ways, LCD & LED

You may not be aware that there is a right and wrong way to clean a LCD screen, but there is.  There a few common mistakes that users make when they clean their LCD screens.  Below is a list, and the following is why.

•  Using Water

•  Using a normal towel, rag, or paper towel

•  Pressing hard on the screen’s surface

•  Using a window cleaner (such as Windex)

LCD screens are sensitive to all the above.  Non of them should be used for the following reasons:

•  Water:  Being that most of the country (USA) used well water, we all understand and know that there are many potential natural impurities in the water like iron, calcium, lime, etc.  So, using this on a scratch sensitive screen would be a really bad idea.

•  Towels (including paper) and rags:  Can be abrasive, as the same with water, it can leave scratches.

•  Pressing hard on the surface:  LCD’s are liquid, and if the liquid is dispersed too much, it will permanently damage the screen.

•   Window Cleaner:  Is meant for glass, not an LCD screen.  It is possible to bring more harm to the screen by creating a permanent haze over the screen using window cleaner.  While this may not happen to all LCD screens it can happen to some.

The right way to go about cleaning a LCD screen is to use a commercially (specifically made) product for LCD care using a lint free cloth in a gentle circular pattern while the screen is off.  The screen can be on while cleaning, it just makes it a bit more difficult to see what it is that your trying to clean off.

LCD Cleaners are safe, scratch-free cleaning for virtually all LCD displays. Because LCD surfaces are especially susceptible to scratches, you need a top-quality cleaner that won’t damage your screen.  Television sets, laptops and PCs demand special attention that only a quality cleaner can provide, and safely.

How to Keep a Computer or Laptop Dust Free?

Keeping a computer or laptop dust free is as much of a challenge as keeping weeds out of the garden.  While this may sound next to impossible, there are some basic preventive measures  the user can take to help keep the inside of a computer free of dust or at least keep it to a minimum.  First let’s see what bad things dust does to a computer.

•  Clogs vents (fans, heat sinks, power supplies, etc.) which leads to over heating and eventually hardware failures.

•  Dust can hold moisture, moisture can cause short circuits, which means you can say goodbye to the computer eventually.

•  Laptops often overheat due to dust clogged in it’s CPU heat sink.

Where Does Dust or Foreign Objects Come From That Get Into a Computer?

•  Plants

•  Animal’s hair and dander

•  Cigarette or Cigar  Smoke

•  Road Dust (Often from city traffic or if in the country, likely from farm fields)

•  Sand (desert conditions)

•  Factory by products such as metal shavings, wood particles, etc.

•  Grease (just don’t have your computer in your family kitchen, period)

Example of what can happen to computer components as seen to the right is when vents get clogged, electronics will begin to overheat.  A component can only take so much heat, so eventually something will have to give.  Many times what gives will be capacitors.  In the case of the picture to the right, this is a video card that overheated and capacitors began to pop. When they pop, they sound like .22 cal bullets being fired.  This particular video card overheated due to common household dust being collected in its vents over a 2 year period. While it was a simple thing to replace the card, the electronic explosions can  potentially cause data lose and of course loss in productivity when you can not use the computer until it is fixed.  Problems such as this can intermittently work will having the blown capacitors for a little while, but eventually will lead to blue screens, boot failures, then eventually the system will not power on.

How do I keep my computer clean?  There are a few preventive measures you can do before you dust out your system.  RCCS has been to many different places with different environments.  Some places are oddly clean to where the 5 year old computer that has never been opened and is completely clean to the opposite extreme where we thought we were going to be attacked by the particles.

Preventative Measures:

• Don’t expose your system to harsh environments like in the above list.
• Don’t smoke at or around the computer.  Smoking is the worst for killing a computer prematurely.
• Keep the computer off the floor and preferably away from carpet or dust collecting areas.
• Keep the computer away from forced air heating or air conditioning.
• Install an air filter into or around the computer. Alternative a computer could be installed into a controlled environment (clean room, very expensive.)
• Keep animals away (Typically next to impossible with cats and dogs.)
• Easy way out:  Air Purifier!

How often a computer is to be cleaned depends on your situation and environment.  Some computers due to their harsh environments may need cleaned out weekly where others are every 6 months to a year.  It really depends on your environment.  A rule of thumb is if you see dust mounding around your exterior vents, power supply, and/or connections, then it is probably time to clean up the inside.

When cleaning out a computer it is best to use compress air to blow out the loose dust.  Do this with the computer unplugged and powered off for at least 30 minutes.  If the compressed air would to happen to blast freeze condensed air onto a hot chip it will crack it and destroy the electronics.  Laptops must be cleaned from inside out as well.  Do not think that blowing air into any computer will help, because it will not.  It will only cause more room for new dust to build up.  If you are not comfortable with cleaning the inside of your computer, then have a professional come and help you.  Other forms of foreign substances such as cigarette smoke is very sticky and can not be just blown off.  This will need to be removed with isopropyl rubbing alcohol by a technician unless you have been trained in doing so.  Computer and electronics are sensitive to static electricity, so be sure you are grounded anytime you are going to be coming into contact with the insides of a computer.
