Simple steps to take when your computer refuse to come up

How do you feel, when you press the power button on your computer and it refuse to turn but you shut it down yourself the last time you used it?
It is frustrating especially when it’s not just cable problem.
There are two major problems with computer
1. The computer refuse to power on
2. The computer is on but it does not boot to desktop may be it always restarts on the way.

In this article, I will be showing you series of troubleshooting tips to take when your computer to on.

First, check the AC current, if it is up to your normal AC rating in your country. Over here in Nigeria, I will check if the AC current is up to 230-240 Volts because that is the normal current in Nigeria. If it is, that means it can power the computer.

Check the power pack: check your power pack if it smells burnt that means the power pack is blown. Some power pack has a switch that can switch to either 110 volts or 230 Volts. If that is how your power pack is then switch it to your country’s current rating.
Now you are sure that the power pack is ok and the current can carry your computer.
Make sure the computer is correctly connected. If it is rightly connected, power the computer. If the computer does not come up,

Check the ram: how do you check the ram? Make sure that the power cord is not connected , Open the computer system unit look if your computer has two ram slot, if it does then remove the ram and clean it also dust the slot with a brush, then insert the ram in the other slot. Connect the power cord and power the computer now. If it is not coming up.

Check the Cmos battery: use a tester to check the battery voltage if it reads lower that 2.5 volts then may be it’s the cmos battery. Change the cmos battery, Next check your cmos jumper and make sure that the cmos jumper cap is in pin 1 and 2, and power the computer. If it does not come up then do what is called isolation.

Isolating system component: this means that you have to isolate all the system component and start reinstalling them one after the other. Finally check if your processor is good.

Check Processor: How do you check processor? Uninstall the cooling fan and heat sink, insert the processor without the cooling fan and heat sink, them connect other component and power the computer. Place your hand on the processor to know if the processor is hot or cold if its cold that means the processor is bad and vice versa. If you can replace the processor, then replace it. If you cannot then say good bye to the computer cause it’s gone.

If you have any problem and questions comment on the post for answers or subscribe to my full feeds for update.

How to remove autorun virus from your flash drives and any hard disk drives

Have you at one time or the other used your flash drive in someone else computer and try to use it on your own computer and you discover that when you click on your drive to open, it opens in a new window?
Do you always see a notepad file with the name BOOTEX.LOG inside your flash drive?

This is a sign that you have autorun virus in your flash drive. Autorun virus is transferred through flash and storage disk from an infected computer to a none infected one. When an infected flash drive is inserted into a none infected computer the virus uses autorun.inf to execute the virus on the system. The virus is always resident in the root directory of the flash drive and other storage devices. It has file extensions like .bat, .exe, .com, .BKK and file name like autorun.inf, o1.com, etc.

Sometimes even when you scan your computer, some antivirus does not remove it.
To remove this autorun virus from your flash drive or any other drive, you have to check if your flash has autorun virus or any root directory virus.

To check your flash drive, click start in your task bar, click run, inside the dialog box type cmd when the command prompt opens, change to your flash drive directory. To change to your flash directory type you drive location and semi column (e.g. K :) and press enter. Then type dir /ah (i.e. dir space forward slash ah) this will display all the files in the root directory of the flash. If there is no virus it will some thing like the screen short below or it will write file not found. If you see any file with .com, .exe, .bkk, .inf, .exe extension on the flash drive. That means you have a virus in the flash. To delete the virus Type del /ah /f (i.e. del space forward slash ah space forward slash f) followed by the file name and press enter to delete the virus
Like the screen short above I know that BOOT.BKK is a virus in my Hard drive I will type del /ah /f BOOT.BKK to delete it. if i had more virus on my drive i will delete them one by one until there is none left.
Note: you have to type the name of the virus the way you see it because it is case sensitive.
After you have removed the files, type dir /ah to confirm if the virus has been remove.

If you followed through and took the steps as I have outlined then you will not see the virus files again that means that the virus has been removed. To remove autorun virus from your hard drives, follow the same procedure above to remove the virus. Then restart your computer and the virus is gone.

6 things to consider when buying a new computer

Is your computer very old?
Is it too slow or the memory is filled up, that you are thinking of buying a new computer?
Before you go to the computer shop, let me show you 6 things to consider when buying a new computer.

1. Computer brand: when buying a new computer the first thing that should come into your mind should be what brand of computer do I want to buy. Brand of a computer is determined by some fact like brand popularity, brand durability and availability of parts in the market.

2. Purpose of the computer: secondly the purpose of the computer should be considered. You have to ask yourself what am I buying this computer for, is it for my personal use, are you using it for DJ, is it for your office, you also have to consider the kind of program that will run on the computer.

3. Facilities available: you also have to consider the facilities that you want the computer to have, facilities like wireless enabled, Bluetooth, camera, card reader etc.

4. Memory Size: you also have to consider the memory of the computer. Computer memory here is the ram and the ram is what runs the applications on the computer so the size of the ram matters a lot, for a brand new computer the ram size is also dependent on the operating system that the computer comes with. If you want to buy a windows vista computer the ram should be like 3GBto 4GB because windows vista needs more memory to run than windows xp, For windows xp 2GBto 3GBwill be ok.

5. Hard disk: the next fact to consider is the size of the hard disk drive. Using large amount of hard disk is the best since some part of the hard disk is assigned to the ram to enable it perform effectively. If you use small size of hard disk and some part is assigned to the ram you will be left with a very small size that makes your computer run slowly. So large hard disk size is the best.


6. Processor speed: another fact to consider is the speed of the processor: you will notice that within the last two years there has been tremendous competition between processor manufacturers. So there are various kinds and types of processor. There are two major processor manufacturers which are Intel and AMD so you have to make your choice based on your research. You have to get a processor with high speed. These are the 6 things to consider when buying a new computer

After considering these facts you are sure to get a good computer when you enter the computer shop.

Types of Computer Virus

Types of Computer Virus

A computer virus is a self-replicating computer program written to alter the way a computer operates without the permission or knowledge of the user. Computer viruses are similar to biological viruses in the way they multiply in number and in the way; they need a host to survive. However, in both cases there must be a cause, such as weak immune system or an expired anti-virus program, in order for the virus to penetrate and spread. The way a computer virus infiltrates your PC depends on the type of virus it is. Because all computers viruses have their own features and factors that make them unique and dangerous to the health of your computer. In this article, I will be sharing with you types of computer viruses so that you can better protect your computer.
Some times when you are infected, you rely know which of the virus is affecting your computer. Below is the list of the most common viruses affecting most computers:

1. Trojan Horses
2. Worms
3. Email Viruses

A Trojan horse appears to be nothing more than an interesting computer program or file, The Trojan virus once on your computer, does not reproduce, but instead makes your computer vulnerable to malicious attacks by allowing them to access and read your files. This makes the virus extremely dangerous to your computer. This virus can be minimized when you avoid downloading unnecessary files and software’s, and only download software’s and files that you are sure of.

A Worm is a virus program that copies and multiplies itself by using computer networks and security flaws. The worm may do damage and compromise the security of the computer. It may arrive via poor system security or by e-mail. Once Copied, the copied worms scan the network for further vulnerabilities and flaws in the network. The best way to protect you from worms is by updating your security software’s. You should avoid opening email attachments from unknown senders.

Email viruses use email messages to spread. An email virus can automatically forward itself to thousands of people, depending on whose email address it attacks. To avoid receiving virus-laden emails, always check that your antivirus software is up-to-date and stay clear of opening attachments. Also, block unwanted email viruses by installing a spam filter and popup blockers.

Other type of viruses exist and one should be careful to prevent himself from getting infected examples are

Boot sector Virus:
A virus that attaches itself to the first part of the hard disk that is read by the computer upon bootup. These are normally spread by floppy disks. To prevent this virus use an antivirus that scan boot files and make sure that the antivirus is updated Examples of boot viruses include: Polyboot.B, AntiEXE.


Macro Virus:
Macro viruses are viruses that use another application's macro programming language to distribute themselves. They infect documents such as MS Word or MS Excel and are typically spread to other similar documents. They usually have the infected file name with .exe extension e.g. m-sword .exe instead of doc. They always run from your driver folder. In system 32 folder. Example of such virus is raila odinga virus. For how to remove raila odinga virus read it here

Memory Resident Viruses:
Memory Resident Viruses reside in a computers volatile memory (RAM). They are initiated from a virus which runs on the computer and they stay in memory after its initiating program closes.

Direct Action Viruses
The main purpose of this virus is to replicate and take action when it is executed. When a specific condition is met, the virus will go into action and infect files in the directory or folder that it is in and in directories that are specified in the AUTOEXEC.BAT file PATH. This batch file is always located in the root directory of the hard disk and carries out certain operations when the computer is booted. Examples are i.exe, autorun.inf.

Overwrite Viruses
Virus of this kind is characterized by the fact that it deletes the information contained in the files that it infects, rendering them partially or totally useless once they have been infected.

The only way to clean a file infected by an overwrite virus is to delete the file completely, thus losing the original content.

Examples of this virus include: Way, Trj.Reboot, Trivial.88.D.

Polymorphic Virus
Polymorphic viruses encrypt or encode themselves in a different way (using different algorithms and encryption keys) every time they infect a system.

This makes it impossible for anti-viruses to find them using string or signature searches (because they are different in each encryption) and also enables them to create a large number of copies of themselves.

Examples include: Elkern, Marburg, Satan Bug, and Tuareg.

File Infectors
This type of virus infects programs or executable files (files with an .EXE or .COM extension). When one of these programs is run, directly or indirectly, the virus is activated, producing the damaging effects it is programmed to carry out. The majority of existing viruses belongs to this category, and can be classified depending on the actions that they carry out.

FAT Virus
The file allocation table or FAT is the part of a disk used to connect information and is a vital part of the normal functioning of the computer.
This type of virus attack can be especially dangerous, by preventing access to certain sections of the disk where important files are stored. Damage caused can result in information losses from individual files or even entire directories.

Logic Bombs
They are not considered viruses because they do not replicate. They are not even programs in their own right but rather camouflaged segments of other programs.

Their objective is to destroy data on the computer once certain conditions have been met. Logic bombs go undetected until launched, and the results can be destructive.

Virus tips

Virus Tips

A computer virus is a self-replicating computer program written to alter the way a computer operates without the permission or knowledge of the user. Some viruses infect existing files on your computer, transforming regular files (like Word documents or system files) into infected files. Other viruses delete certain types of files on your computer. Virus sometimes interferes with your mouse cursor making it hard for you to control. A virus can spread from one computer to another when its host is taken to the uninfected computer, for instance by a user sending it over a network or the Internet, or by carrying it on a removable medium such as a floppy disk, CD, or USB drive.

Viruses are sometimes confused with computer worms and Trojan horses. A worm can spread itself to other computers without the need to be transferred as part of a host, and a Trojan horse is a file that appears harmless. Worms and Trojans may cause harm to a computer system’s hosted data, functional performance, or networking throughput, when executed.

Symptoms of a virus infected computer
The following are some major symptoms that show that a computer may be infected:

• The computer runs slower than usual.
• The computer stops responding, or it locks up frequently.
• The computer crashes, and then it restarts every few minutes.

• New icons appear on the desktop that you did not put there, or the icons are not associated with any recently installed programs.
• Strange sounds or music plays from the speakers unexpectedly.
• A program disappears from the computer even though you did not intentionally remove the program.
• You see folders created inside folders, with the name of the containing folder and then “EXE” extension i.e. new folder.exe
Note: These are common signs of infection. However, some signs may be caused by hardware or software problems that have nothing to do with a computer virus. Unless you have a good and an updated anti virus Software, you may not be certain whether a computer is infected with a computer virus or not.

In this article I will be sharing with your 6 techniques/strategy to becoming your own computer engineer so you don’t have to call an engineer when your computer brakes down.

1. DON’T FEEL FRUSTRATED

Don't be afraid of computer problems. It is often the best opportunity to learn. Trouble-shooting is part of the fun of owning a computer. Imagine the satisfaction you could get by solving a problem yourself.
Of course the fun could run out quickly once you are frustrated and have spent too much time on the same problem. If you feel frustrated, it's time to leave it for a while and go back with some new ideas

2. CONFIDENCE

Confidence is the first technique to solving any computer problem, believing that you solve the problem will make your mind to think and also makes you not to quit on the problem, it prompts you to take steps and you will be surprise to know that you have solve the problem because your confidence was in place.

3. RESEARCH

In computer engineering research is a major criteria if you must be relevant. The difference between you and the other engineer is just the amount of knowledge you have on the field and this knowledge come as a result of deep research. how to make research, if you have a problem and you don’t know what to do just examine the problem then go on the net and search solutions for that problem. e.g. if your computer has raila odinga virus and your antivirus is not removing it, you can type how to remove raila odinga manually on www.google.com, read through the sites that are saying what you want to know about click on the site ti read the full details that way you have adequate knowledge to solve the problem. Note that there is no problem that you will encounter in your computer that no body has encountered, so going online to search for solution is a smart way to solve the problem.

4. TRIAL-AND-ERROR

When your computer encounters a hardware problem, what you need to do is to know the kind of problem and the hardware responsible for the problem, because Personal computers are highly modular by design. The most powerful technique is to isolate specific component by trial-and-error. Swap compatible components and see if the system still works. Try that peripherals on a different machines and see if the same problem occurs. Make one change at a time.


5. ALWAYS TAKE NOTE

Take notes of what you have done and all the error messages. You may need to use them later. For instance, when you see an unusual blue screen with an error message. Copy the entire message onto a piece of paper. In many situations, that message may point to the right direction in getting the problem solved quickly. Always remember to use the internet when it becomes difficult.

6. TROUBLESHOOTING HARDWARE

It's OK to open a computer case and take a look inside. There is only 5V and 12V DC voltage supplied to the components outside the power supply. Those who have never seen the inside of a computer are often amazed by how simple it looks. Of course, still always power down and unplug the power cord first.
More than 70% of all computer problems are related to cabling and connections. Ensure all cables are connected firmly. IDE and floppy ribbon cables and power cables can often go loose. Ensure microprocessor, memory modules, and adapters such as video card and sound card are inserted correctly and didn't "pop-up" during transportation.
