There are several problems associated with computers irrespective of the size, OS and brands; desktop computers, laptops, MacBook, Windows PC etc and some of the common defects affect the starting of the PC.
To carefully deal with “my computer power is on but laptop does not turn on” problem, computer turning on and off again, failure to boot, standby green light on motherboard but wont boot, beeping noise, no fan and others, you should understand the signs relating to each problem type.
3 Categories of PC Starting Problems
The computer starting problems can be basically grouped into three, Power on but not turning on, OS not starting (Windows booting) or the hard disk not detected or similar problem. There are signs to note in order to get where the problems lie but here today, we want to give quick solutions to these problems.
Even though you don’t know jack about computer repair, you should be a ‘small engineer’, study the booting process and pay attention to some signals and get to know when the computer stops the process of coming up; differentiate between when the laptop can’t turn on st all, stops working when it’s trying to boot Windows or in BIOS.
This will aid you to understanding the cause of the problem or at least, the parts of the system that’s faulty.
The computer won’t turn on
When your computer does not turn on at all, it’s possible the problem is with your power source ( the electric socket and others) or the cable wire you plugged and connected to the computer system.
It could also be the motherboard that’s not working properly or the computer hardware. In some cases, the problem could also be from from the computer processor (CPU)
If you want to take bold step to solving the said problems and also minimize the cost of assessment and repair when you take it to the engineer, you can do ‘guess work’ by testing the socket with another electrical appliance and also test your laptop with another cord.
If there is no light on the motherboard, you can ask a friend to help you with his or hers to use with your laptop and if it works fine, that means you need to replace the motherboard.
Hard drive is not detected or related problem
If your hard drive is not recognized in the BIOS of your computer and the hard drive is making clicking noise, it means there’s a problem with the hard drive, either it’s internal or external hard drive is to be loaded.
There are several causes for this, if you’ve just changed the hard drive, it may be that the ATA or Serial ATA drive is not installed properly or not enabled in the BIOS, it could also be problem in the configuration of the drive or your hard drive is not working, among other problems.
Depending on the problem, the computer may beep 3 or 4 times on startup or continue beeping while the system is running. In some cases, it can be making random beeping noise from the computer central processing unit and there would be no display on the monitor.
Each of these beeping sound is a signal to fine tune the problem with the hard drive; however if the laptop stops the booting process, the defect is for sure from the hard disk and you’re just one step from fixing the issue especially if your computer pop up a message about the system setup, that is, the system BIOS or CMOS setup.
Computer not booting into Windows
This seems to be the commonest problem experienced with computer booting problem. Unless you choose to boot your computer from other storage or safe mode, it’s expected to boot into Windows and load your programs but if there’s problem with any of your applications, the PC may not be able to load the operating system.
We’ve covered this problem and solutions to it extensively. You can boot into safe mode, use other storage etc, backup your system and use Windows startup repair tool. If this problem persists or reoccurs later, you may need to install new Windows. Just make sure you create a backup.
There are several reasons you may want to factory reset your iPhone, it may be because you’ve just bought a fairly used iPhone, you’re about selling the one you’re using, you jailbreak your iPhone and it’s now infected with virus from non-certified apps or you just forget your password; in whichever way, it’s important you know that you’re likely going to delete your iCloud account, the Apple ID and password or lose data if you’re not sure of what you’re doing.
If you’re resetting your iPhone when you forget your password and you want to restore it, the first thing is to backup your data to avoid losing your media files, contacts and other information.
There are iPhone backup apps and you can transfer your data to other devices, back up with iCloud account or sync with computer and migrate your videos, Audio-books, pictures, contacts and others to the PC. After that, you can continue with factory reset.
There are many ways you can do this; you can delete an iCloud account if you don’t know the password, you can erase your Apple ID with your password and when ‘Find My IPhone‘ is on or factory reset with iTunes or without it.
To factory reset your iPhone without computer
Go to your iPhone settings, tap General and scroll down to click Reset. To completely delete everything on the phone, select ‘Content & Delete’settings and input your password to authorize this action and your iPhone OS will be reinstalled. You can now restore your data from backup and make other necessary settings and start using the phone again.
There are other preferences on the ‘Reset Tab’, some to help you manage the iPhone memory space if you’re running out of memory and the phone is becoming slow, hanging or freezing up; some to reset some personal settings and preferences.

After reset, you’ll see the “Configure” option which will appear on your iphone screen and you can now follow the inbuilt iOS configuration panel to reset your iPhone.
If the previous ways I discussed is not helping you, you can reset your iPhone in the recovery mode. This is how some people unlock and reset locked or stolen iPhone without iTunes Cloud account or Apple ID password or better contact Apple support or discuss it with other users in the Apple support forum.
To factory reset using the Recovery Mode
Just as I’ve said, the last option if you’re having problem resetting your iPhone may be the recovery mode method, when your iPhone is disabled and you want to reset it without iTunes or it’s locked and you can not use it.
The first thing is to turn off the phone ( if the iPhone can not be turned off, press and hold the home button and power button at the same time for few seconds to turn it off)
Let’s start with factory reset using iPhone app like Dr.Fone toolkit repair
With this iOS app, you’ll not have to worry about backup as it’ll handle everything for you. It has versions for android, iOS devices and PC.

How to Restore iPhone with ipsw files installation tools
This method is only suitable for iPhone geek or a developer. You can install a particular version of the iOS software with .ipsw files if you don’t want the new automatically updated firmware.
Search and find the compatible .ipsw file for your hardware and download it, connect your iPhone to your computer, open iTunes, select your phone and set the phone to the Restore Mode. After that, Click update to open the .ipsw selection dialog, press and hold the Option key and click Update to select the .ipsw file you’ve just downloaded and use it.

With iTunes, you’re able to connect multiple devices with your account and share your music, albums, audiobooks, apps etc across these devices; phones or computers. To do this, you need to synchronize your iPhone to your computer, iPad, or iPod in order to transfer your song playlists to these devices.
However, In order to use this feature, you need to activate your laptop in your iTunes account.
How do you now authorize a computer and add a new device to your iTunes account?
How to create Apple ID The first thing is to register your account and create your Apple identification code (Apple ID). To do this, Go to settings, Tap iCloud and create a new Apple ID, Enter the required information like your date of birth (DOB), Name and create an iCloud email address or select the existing email.
If you already have Apple ID and contents are in your Apple ID account but want to transfer the contents to other devices, you don’t need to create another account again, jump the account creation stage above and authorize your PC.
How to Authorize Computer Go to the Apple store menu on your new device and tap “Enable this computer” option and enter your Apple ID and passcode, after that, click the activate button and viola, your new device is now authorized to use your purchased contents on the iTunes store. With this, you can share your account with your spouse and family with just one time purchase.
Note:you cannot authorize more than five computers but iOS devices (iPad, iPod touches and iPhone) are exceptions. However, If you’re not able to authorize a new computer, it’s likely you’ve reached the limit and only need to manage the authorized computers by deauthorizing some of it; that’s the simple fix.
If iTunes says your computer is not authorized but it is, and keep asking you to authorize computer that’s already activated each time you want to add the device, this is becoming common as iOS devices are sometime counted even when they’re exceptions to this 5-computer- limit, just contact the Apple support to help you rectify this, sometimes, fee is attracted.
If you’re having authorized computer that is now dead, you no longer have or want to use with your iTunes anymore, you’ll have to de-authorize such computer.
How do you now find out to see the list of authorized computers on your iTunes account and which one you need to deactivate?
Go to the Apple store, Tap account and click View account, Enter your passcode. Tap the iCloud and select “Manage Device” and you will see the number of authorized computers associated with the Apple ID. Note: there’s no information about each computer that’s authorized, you can only see the number of the list.
How to De-authorize all computers If you want to de-authorize all your computers and reauthorize new PC, you can only do this once in every year and this seems to be the Almighty solution to deactivate old PC that are authorized but no longer used.
To do this, open the iTunes store, go to the menu bar and choose your account, Tap account authorization and click on the De-authorize button. Your login details would be requested and just fill in your Apple ID and password and click De-authorize. Once this is done, your computer would be deactivated from getting contents from your Apple ID.
If you want to de-authorize all synchronized computers, after you’ve logged on, scroll down to the tab you see “Computer Authorization” and Tap De-authorize all and confirm this action and all computers synced to your account would be deleted.
If you’re in doubt of what happens when you de-authorize all the computers in iTunes, you don’t need to worry as you don’t lose your songs, playlists or apps etc; everything will still be in your account, only that the computer you’ve de-authorize would not be able to access and use these contents unless it’s reactivated again.
Scanning your document from Mac computer should not take much effort since we’re having different ways you can do this and modern scanners that are now developed are more sophisticated to make everything goes swiftly.
I’d like to discuss two ways you can scan document on Mac OS X system. You can do this directly from scanning machine or using image capture software
To scan the document using the scanner, connect the scanner to the computer, make sure you use the appropriate USB cable and plug to the appropriate port on the Mac system, go to file on that specific page and click on the import button.
You can set other preferences like the resolution, size, the format to save your files and others.
Click on the icon for printing and scanning and select your scanner from which you want to scan the document and click print, another option would pop up and you can now select Scan.
Print and Scan Printing If you want to print the document, place the document in your ADF (automatic document feeder) or on the scanner glass, select mode and scan size. However, if want to also scan; Once you place your document on the scanner glass, select “Flatbed” (Note, If you’re not using ADF scanner, the option will not come up)
Set the color, either “Black and white” or “Text”, Select the resolution at which you want to scan the document, the paper size and how the content is going to fit onto the page, that is, the soft copy of your document, and also the orientation.
If your scanner machine can make duplex scanning, Here you can select whether you want to scan duplex from the ADF and select the destination folder or the target application.
Enter the name you want to assign to your scanned file and Choose the file format. Also, you can make some adjustment on the brightness, color, saturation of the file and others.
Image Capture App
If you’re using image capture application, you can use the image capture with Mac OS X 10.7, however the ICA scanner driver must be installed. For some models, CUPS printer drivers are installed or Mac OS X 10.7 has the ICA scanner driver.
Once you connect your computer and scanner together, launch the image capture/editing program on your laptop and select the scanner, place the document on the ADF or on the scanner glass as previously explained
What is the best practice for organizing files and folders on my laptop computer? this is one of the questions I usually receive when I publish article about data management. It is true that we don’t fill up our offices and homes with physical documents any longer, yeah, the days are gone.
Now, we use our laptops for both personal use and businesses, not only online businesses but also also offline businesses, to complement some of our activities and to also improve efficiency.
However, you can still encounter the challenges of unorganized documents and files, especially if you use your laptop for business more than for personal use.
Even for personal use, over time, you can have hundreds of downloaded files, photos, and videos which can all contribute to slow operation of your computer and the computer’s performance can suddenly become poor.
So, if you want to manage the files on your PC properly and keep everything nice and clean on your computer, here are the most important things to take note.
Regularly delete old and irrelevant files Most of the files we prepare or download become less important over time but we don’t usually put our mind in finding these files and delete them; we even have duplicate copies of these files sometimes or even have loads of images that are extracted from webpages.
Tracking these files and getting rid of them from our PC could be a daunting task as we’re most lazy to carry out maintenance activities. To ease things, you can download duplicate file remover app and a junk file cleaner app that works with your computer OS, both will automatenthe processes and get unused files deleted fast.
Categorize your files One of the best way to manage your files well is to organize the apps, choose labels and create different folders, each containing files with similar properties or importance. You can create big folders and some sub-folders.
For example, you can create business folder, and sub folders for sale, marketing, revenue etc. With this, you can easily locate your files, update or delete the ones you don’t want again without hassle.
One mistake we often make and lead to loads of duplicate files is to save a single file in multiple directories, this is because, we want shortcut in locating them for immediate use.
You should avoid saving files to your desktop, this can affect the booting of your laptop negatively and it really mess up your laptop.
Carefully select the appropriate folder that fits every single file you’re either downloading or created and everything would be well organized for your comfort and also the health of your computer.
Always Backup your file Hmmm, we never understand the importance of backup until our system crashed or we had problem with our file storage. Many computer don’t realize how much important it is to backup files, we only think this is not necessary especially if the computer is not used for business purpose.
Even when we backup, we don’t usually inculcate the habit of routine backup in order to be totally safe from losing important files from our PC.
I still find it difficult to forget the ugly scenario when I was in college and lost all the files on my computer when I tried to update the Windows on the system. I had about two uncompleted books I was writing and couldn’t start from the beginning to rewrite the book again.
I never knew there are even several data recovery apps that can help out in that situation, but it is always better to have all of your files stored somewhere that’s secured.
You can sign up for a cloud storage service that will automatically sync up your files as you add them. If you are working with a limited storage space, we recommend that you keep only your important files there.
Routine check up This is somewhat impossible for many, especially when you’ve to make this a ritual, checking your files and separating the less useful files. You can be doing this weekly or if you’re always having busy schedule, you can make this monthly exercise.
It should not take more than one hour or two, get a coffee or chocolate, open your laptop and sort the old files you’re not likely to use again. Keep them I’m a separate folder and review them, after that, you can decide to delete them to lessen the load of your PC and make it work better.
Takeaway File management is very important, not only with physical file folders but also on your computer. You may find this not so important or stressful, yeah, we’re likely to be lazy about it but it’s so important we do. We can’t pay the price of losing some important data on our computer.
Either the system is for person use, business use or both, always check your list of files, group them into different folders, get read of junk files, some logo or banner extraction from pages; this small files, when compounded, can occupy much space without our notice.
Take care of your electronic document, just the way you will care for your physical document, and even much more.
Have you heard of the programming language,HTML (HyperText Markup Language) and CSS (Cascading Style Sheets)? If you have, then it is good, and if you have not, then you will become aware of these two languages through this post and other articles about programming languages on this blog.
You will learn how to make stylish, standout and responsive image gallery with simple HTML and CSS photo gallery codes. We’ve made it easy with free template you can follow line after line.
Before going further and digging dip, you’re advised to open notepad, and save the file with name index.html in a folder (name the folder, gallery). You should make another folder with the name, images in gallery folder. You should put three images of the same size, for example 400*400 size images in images folder. Write the following codes in index.html file:
In the body (between <body> and</body>) of your HTML, you should write the following codes:
<h1>Gallery</h1> <div id=”gallery”> <ul> <li> <img src=”hxxps://drsamrobbins.com/wp-content/uploads/2014/03/apples-burn-fat-400×400.jpg” class=”pic”/> <label>Caption Here</label> </li> <li> <img src=”hxxps://noao.edu/image_gallery/images/d2/m51-400.jpg” class=”pic”/> <label>Caption Here</label> </li> <li> <img src=”hxxps://i.pinimg.com/736x/9e/4a/1e/9e4a1e2ce8fdd5e8f2eafba6f7c34bf0–glitter-wallpaper-black-wallpaper.jpg” class=”pic”/> <label>Caption Here</label> </li> </ul> </div> <!—that’s how comments are made in HTML (start comment)(
Note: <div> is an HTML tag that divides HTML body into portions, and h1 is a heading tag, <ul> is a tag for unordered list, <li> is a tag for list, and class is a child of id in HTML. I have used links to generate pictures in HTML body rather than using the pictures in the folder.
Note 2: Change the hxxp in bold to http
<!—that’s how comments are made in HTML (end comment)(
Now you should open a blank notepad document, and you should name it style.css. Put style.css file in the same folder where your index.html file is. In the style.css file, write following codes (note that comments in stylesheet files are given by typing // next to semicolon):
h1 { text-shadow:gray 3px 3px 3px;//will give text a gray shade box-shadow:gray 3px 3px 3px 3px;//will give box a gray shade }
#gallery ul li { border:5px solid black;// will create a border of 5 px with black colour float:left;//will move the images to the left width:27%;//images will be created with 27% width margin:1%; //will place images at a distance of 1% from one another position:relative;//image will be positioned list-style:none;//will hide the bullet points }
#gallery ul li .pic { width:100%;// image will be made with 100% width height:200px;//image will be 200px in height -webkit-transition:-webkit-transform 3s linear;// it’s a CSS3 property for transformation }
#gallery ul li .pic:hover { -webkit-transform:rotate(360deg);//will rotate the image to 360 degree; you can also use 180deg instead of 360deg }
#gallery ul li label { background-color:black;//will color the background of label, black color:white;//will color the text of label, white bottom:0%;//will fix the label at bottom opacity:0.5;//will make the background color 50% lighter position:absolute;//it is often used with relative property height:30px;//height of the label will become 30px width:100%;//will make the width of label, 100% text-align:center;//will align the text in center -webkit-transition:height 2s linear;//will call –webkit-transition property } #gallery ul li label:hover { height:80px;//caption will rise to 80px, because of hover command }
You can use above codes to try out making a standout gallery yourself. Remember –webkit-transition property is not supported in Internet Explorer, you should use the Google Chrome or Opera browser to test above codes. You should remember that ids are called by # in stylesheet, and classes are called by dot (.) in stylesheet
Interactive and responsive gallery looks more pretty, hence you should also try to make standout galleries. This is the same way how Google shows images on browser. HTML and CSS languages are not very difficult to learn, and you need to give time to study these languages as they need practice.
The more you practice HTML and CSS, the more command you will have over HTML and CSS. HTML and CSS are interesting languages, hence you will not face problem learning it.
Following are some of the things about HTML and CSS that you must know about:
HTML tags are both open and closed. For example, <p> is an open paragraph tag and </p> is a close paragraph tag.
<h2>, <h3>, <h4>, <h5>, and <h6> are heading tags in HTML, whereas <h6> has the lowest size, and <h2> has bigger size than h3,h4, and h5 respectively
<br>This tag breaks the line in HTML
In order to create a circle through HTML & CSS, programmer must define an item either through id or class in HTML, for example <div id=”box”></div>, then the programmer must define same height and width in style sheet with background-color and border-radius as shown below:
#box
{
width:200px;
height:200px;
background-color:blue;//will color the background, blue
border-radius:100%;//will make square a circle
}
font-style, font-weight, cursor, padding, margin, and * are some of the commands that are often used in CSS
How much knowledge have you gained about HTML and CSS through this post? Now, you can make a gallery just like Google images gallery. You are also aware of various html tags and stylesheet code now. You should carefully go through this post again, and you must also open notepad to practice creating standout gallery through HTML and CSS.

Computer is an electronic device that’s capable of processing and interpreting data to give output; this is the common definition to computer in our high schools.
Ever since computer has been invented by Charles Babbage, although in what could not be regarded as the modern computer that we use today, it has evolved beyond just processing data, become so relevant as good as man in every sphere of life.
Computer has found itself being deployed and used in Education, law, arts, engineering, science, health, accounting, used in almost all companies in the world performing simple tasks to complex ones and it’s become a common household tool with almost 2 billion computers that are used in the world.
What is Supercomputer and what is it used for?
Computer’s performance is measured in MIPS, meaning, million instructions per second but today, we have supercomputer which is known as high performance computer (HPC), the set of biggest, largest and fastest computers in the world with high processors that are capable of processing quadrillion of FLOPS. It’s performance is generally measured in floating-point operations per second and some in P(eta)FLOPS.
After supercomputer was introduced in the middle nineteenth century by an American electric engineer, Seymour Roger Cray (the father of supercomputing), the supercomputer industry has started attracting funds across Europe and asia since these machines can perform multiple tasks that hundreds of thousand of humans can not perform at a time.
What are Supercomputers used for
Supercomputers are so much relied upon for weather and climate related research, monitoring of storms and forecasting, Oil & gas exploration, mechanics, aerodynamics, medicine etc.. and their tasks are dedicated.
The Top 10 Most Powerful Supercomputers in the World today
Position Number 10
