WHY YOUR COMPUTER FAIL TO START

The causes of computer failure to boot up can be broken down into four categories as follows:

• Bad electrical connection
• Power supply failure
• Operating system failure
• Hardware failure

Each of these categories holds a number of issues that computer fixers see on a very regular basis. The most common issues are explained on this page.

In many cases, problems can be fixed and your computer up and running again in a short amount of time.

Bad Electrical Connection

This is a very common causes of computer failure in older computers. The constant heating and cooling of the computer, atmospheric conditions and dust can all play a part. Most of the time the issue can be solved in just a few minutes.

This category includes:

• bad connection between a memory module and the motherboard; or
• bad connection between the video card and the motherboard; or
• loose cable

Memory modules need to be reseated

It is a very common cause of boot failure that a memory module is not properly connecting with the motherboard. If just one of the many pins on the module fail to connect in the motherboard slot, the computer will not start. You will not hear the usual beep, nor will any text appear on the screen when you try to boot. The computer will be lifeless when you turn it on except perhaps for the case and CPU fans. Take the power cord out the back of your computer and open the case. Try taking out the memory modules and the putting them back (with a bit of a shove). This is called reseating. Sometimes you have to repeat the process a few times. The bad electrical contact occurs as a result of a gap opening up, or a bit of corrosion or dust getting between the electrical contacts. Reseating works in very many cases.

Video card needs to be reseated

This is much the same problem as with the memory modules, except the video card need to be reseated. Of course, your computer may not have a separate video card. Furthermore, if you have a laptop and it has a separate video card, then you can only get to the video card if you take the laptop base apart. Laptops are really unfriendly in this matter. Unless you have experience, or you can find a step by step guide to disassembling the laptop base, don't do it yourself.

Loose cable

Particularly if your have been moving a computer around, or you have opened the case for any reason, it is perfectly possible that a cable is loose or there is not a good electrical connection. It is always worth a try to recheck cables by removing and re-attaching each in turn. The cables to be mainly concerned about are the ones that connect the hard drive to the motherboard and the cables from the power supply unit that connect to the motherboard.

Power Supply Failure

Power supply unit is broken (desktop computers)

If you computer is completely dead when you turn on, that is no fans, no lights, nothing, the your power supply may have failed. This is not uncommon. Replacing a power supply is easy and not that expensive. If you are a novice, just disconnect all power supply cables, unscrew the unit and take it to a computer supplier. If you do this you will ensure that you get a new one that will have the connectors you want and the right strength in output Watts.

Laptop Battery

If you have a laptop, check that the battery is connected properly. Remove the battery and reattach with a bit of a hard shove in case there is an electrical contact problem. If this does not work, it might be that the battery has no charge. Either the battery is failing or the supply of electricity to the battery is failing. Take a look at the socket where the lead from the battery charger goes. If there is a thin pin in the socket, is it very wobbly. It is not uncommon for someone to trip on the battery charger lead and break the socket where the battery charger lead attaches. It is also possible that the battery charger has died. You can purchase a universal laptop charger for around $60 and a new battery does not cost that much if you order direct from China via Ebay or Ali Express.

Operating System Failure

Generally, if a computer turns on, LEDs light up, the hard drive makes a few noises and some text appears on the initial screen, then the probable reason for boot failure is the operating system.

Corrupt or missing file(s)

When the operating system fails to start and the hardware is not a fault, it will be because one or more essential files that the operating system needs to start have come corrupt or missing. The two most probable causes of this are:

1. The hard disk is old and beginning to fail and/or
2. An infestation of the computer with malicious software

If it is a matter of missing files or files that do not read, then running software such as Spinrite can make a difference. Spinrite will often repair files and make them readable again. Following a scan and repair by Spinrite, you may be lucky to get operating system to boot up again. If you are lucky, take immediate steps to back up whole hard drive using good software such as Acronis True Image. This software will create an "Image" of your hard drive which you must store on an external hard drive. You can then purchase a new hard drive and transfer the image, however you will need a hard drive docking bay. A docking bay in effect turns an ordinary hard drive into an external drive and therefore information (the image) can be copied to it before it is installed into a computer.

Many people faced with this situation resort to reinstalling the operating system but this is often not necessary. A good computer fixer/repairer may well be able to repair the missing or corrupt file problem. If the problem is repairable, and it usually is, you don't have to start all over again reinstalling every bit of software you had.

Attack of malicious software

Malicious software is a generic name of viruses, trojans, worms and rootkits i.e. the nasties you need to keep out of your computer. A word of warning, if it is the case that your operating system has been damaged by malicious software, then often it is very difficult to make repairs and get the computer to boot up again. It's not impossible, just difficult. Malicious software is so incredibly sophisticated these days that even good proprietary Anti-Virus software cannot deal with it. If you scan a hard drive that will not boot using a rescue disk provided by the makers of anti-virus software, it is likely that the malicious software will be detected and repairs effected. However, the repairs may not be 100% and the computer will still not boot. It is then necessary to find which system files in your computer have been changed/corrupted by the malicious software and this can be very challenging to find and fix.

Hardware Failure

Video card failure

Not all computers have a separate video card. It is easy to tell if your computer does. If the monitor lead connects to your computer in the same area where all the other leads plug in, then your computer does not have a separate video card. On the other hand, if you monitor lead plus into your computer in an area well away from other leads, the chances are that you do have a separate video card.

Video Card with Fan	Video Card with Cooling Vanes

The trouble with video cards is that they often only have a life span of about three years. This is may be because they get very hot. That's why they have a fan or cooling vanes. If the video card fails, your computer may not start at all.

Fortunately, they are easy and inexpensive to replace. Most video cards cost around $40-80. However, you could just try plugging in the monitor to other (not in use) video monitor port (see yellow arrow).

If this works, then you know for sure that the additional video card is broken. But you can use the video component that is usually built into the motherboard but the picture may be less quality.

If there is no other place you can plug in your video monitor lead, then you will need to replace the video card.

Hard drive failure

Sometimes hard disk drives just break. If you hear clicking noises, then this is a likely scenario. This is a bad scenario! Mechanical failure of the hard drive usually spells the end of all your data on the disk. The only way that data can be salvaged involves taking the disk apart and this can only be done by specialists and it will cost very large sums of money.

Motherboard Failure

Working out that a motherboard has failed is really a process of elimination. If it is not the video card, power supply, memory modules, hard drive, etc, then the hardware failure is presumed to be in the motherboard.

For laptops, a failure of the motherboard often spells the death of the computer. This is due to the high cost of replacement. A new motherboard might only cost $100-150 if you buy overseas via Ebay or Ali Express, but it takes a good computer fixer about 1½hours to completely disassemble the laptop base, change motherboard and reassemble the base. The labour cost could therefore comfortably add another $100-$150. Still, if it is a good computer, many people may opt for this cost rather than the cost of a new computer.

For desktops, the situation is much better. Motherboards are cheaper and much easier to insert,

HOW TO KEEP YOUR PC BATTERY SAFE

These are few tips to do for your battery

Save cycles, save your battery

All laptop batteries are built to handle a certain number of usage cycles, usually somewhere around 500, and often more. Each cycle of use decreases the battery’s capacity, so the less you drain it, the longer it’ll last — all other things being equal.

So where do you start? Begin by visiting the Power Settings corner of your laptop. Many computers offer the ability to switch to an “eco mode” that automatically adjust the way power is used (such as dimming your screen brightness) to conserve battery energy.

Also pay attention to hibernation modes. Ideally, you want your laptop to enter into hibernation before the battery is totally drained – as well as during downtime when you won’t be use the laptop for a while.

To save even more power, take a tour of your apps and quit any background apps that are steadily eating into your battery energy. In Windows computers you can look at your System Tray, your Task Manager, and your Processes tab to see which of those little icons really isn’t necessary. In OS X you can see what’s running both in the taskbar to the upper right and the pop-up menu – cloud storage services or video players that you aren’t using can be safely shut down. 

Keeping your battery in zone

In ancient, less enlightened times, there was a problem called “battery memory” which caused batteries to “forget” their full charge capacity and start charging at lower and lower levels. This problem doesn’t exist anymore thanks to modern lithium-ion batteries, but it has led to a lot of poor advice and arguments about battery care based in information many years outdated. It’s time to clear the air.While you can leave your battery plugged in for as long as you want (heating issues aside), there is a sweet spot for battery life that you can use to get the most cycles. You see, letting a battery charge to 100 percent all the time does tend to wear the battery out more quickly, while letting it fall too lower in the other direction too often can also be bad news – sort of like forcing yourself to run until your knees hurt. The happy middle ground is, according to Battery University funder and Cadex Electronics CEO Isidor Buchmann, is somewhere between 40 percent and 80 percent battery life.

So the best thing you can do for your battery is charge when it reaches 40 percent, and unplug it when it goes past 80 percent. Obviously this means applying a little OCD to when you plug and unplug your charger, but your battery will thank you in the long term by lasting longer.

Environmental concerns: all about temperature

Today’s lithium-ion batteries are durable little guys, but they can only take so much heat. Anything above 95 degrees Fahrenheit can damage your laptop battery permanently.

This leads to some common sense suggestions. For example, if you are charging up your battery and it starts to get seriously hot, pop the battery out and give it a break so it can cool down or you can move to someplace with a lower temperature. Likewise, keep the laptop off your actual lap. If testicular damage and discomfort weren’t good enough reasons, you’re also making the problem worse and often block vents.

Cold temperatures usually aren’t a problem, and storing a battery in a cool place is recommended, but don’t leave your laptop in freezing temperatures, ever. Too much cold can kill the battery permanently.

If you want to watch temperature even more closely (say, you live in a particularly hot climate), there are a number of apps you can run that will monitor laptop heat. This includes CoreTemp and Real Temp, which you can download for free.

Giving your laptop some TLC

Most people just let their laptop battery sit, snug inside the laptop, doing its job. But it’s a good idea to take your battery out from time to time and show it a little love. Every few months, detach your battery and give it a careful wipe with a soft cloth – get rid of any dust, and make sure the contact points are especially clean.

Note that this only replies to models with removable batteries. The newer MacBooks in particular have infamously trapped batteries. But if your battery can’t be easily removed, you don’t need to worry about it getting dirty.

Things to avoid

Want the best battery? Here’s a quick list of bad practices.

• Full discharges: As mentioned, when a laptop battery discharges fully – forcing a shutdown – the battery struggles to return to its full charge. If it happens frequently, the battered battery will eventually give up the ghost. Even when running a discharge cycle, don’t let the battery drop to zero percent. Instead, use hibernation modes that trigger around five percent battery life.

• Reliance on hibernation modes: This is a similar point to the first. If you are constantly forcing your laptop to hibernate in order to save the battery, you aren’t keeping your battery at the ideal percentages. Rethink your laptop habits.

• Long periods of inactivity: If you have to leave your battery unused for long periods of time, then make sure it has around a half charge. A depleted battery can die forever if not recharged soon enough. But generally, batteries need a fitness regimen to stay in peak condition. If possible, keep using and properly charging your battery as long as you have it.

• Hot summer days: Obviously you can’t always avoid hot summers, but you know what this means: Keep your laptop cool. Store it indoors, avoid direct sunlight, and keep it out of hot cars during warm days

HOW TO INCRESASE COMPUTER PARFORMANCE

These are simple tips to follow to maximize efficiency of your pc

1) Use Microsoft Fix It

Microsoft Fix It is a free tool from Microsoft that will help users of Windows 7 or earlier to clean up and perform many simple maintenance problems.

2) Reduce Items that Run on Startup

If your computer takes a long time to start up, the first thing you want to do is see everything it starts when you hit the power button.

To do this, click on the Windows button, click “run,” and then type “msconfig” into the box. Click on the “Startup” tab. Some things you want to leave alone. For example, your Antivirus. Others, such as Adobe Acrobat or Google Toolbar Notifier, you don’t need to startup with your computer.

3) Remove Programs No Longer In Use

Along with preventing every app on your computer from starting with Windows, you should also review which programs you no longer need and remove them.

Access the uninstaller tool from your control panel and use that to uninstall programs you don’t use. I regularly do this, of course, as a software reviewer.

4) Clean Your Drive

Clean up your drives by typing “cleanmgr.exe” into the run menu to access Disk Cleanup. This is that “search programs and files” box that shows when you hit the Windows Start icon, usually in the lower left of most screens (although you can move it to any part of the screen).

5) Consider Switching From Internet Explorer to Chrome

If you are using Internet Explorer (IE) as your Web browser, it is time to upgrade. Make the Google Chrome download the last thing you do on it.

Chrome is faster and has fewer bugs than IE 11. (Sorry, IE users.)

6) Clean Your Browser

Regardless of your browser, you should clean it out regularly. To clean Chrome, click the three bars icon in the upper right corner, then click “Tools,” then “Clean Browsing Data,” and then check the history boxes, cookies and cached items.

Or, download CCleaner which does a great job on the five top browsers, registries and Windows, overall.

7) Scan For And Remove Malware

Anything that starts with “mal” must be stopped. You should regularly scan your system to get rid of any malware that may be slowing your computer down.

Comodo Cleaning Essentials is a top rated free tool that does this. Avast also has free tools, as does Norton.

8) Scan For And Remove Viruses and Spyware

In addition to performing regular scans on your computer for malware, you should also regularly scan for viruses and spyware.

Access your antivirus and manually perform a scan. You can schedule these weekly. Just make sure you do so when you won’t be using the computer. Also, having more than one antivirus on your computer will slow it down, so unless you are wanting to be incredibly thorough, and perhaps a bit redundant, it is better to run only one.

9) Make Adjustments For Better Performance

If you want better performance and don’t mind losing visual effects such as mouse shadows, click on “computer,” and then “system properties,” and then “advanced system settings.” You will find a performance settings button that allows you to select “adjust for best performance.”

You can also reduce your screen resolution, which can speed things slightly and improve battery life when running on it.

10) Def rag Your Drive

You should defragment your drive or schedule it to perform this action automatically. In general, you can do this monthly. However, if you excessively download, move, uninstall, or install programs, you may need to do it more frequently.

If your computer is running slow, you can manually analyze the disk to see if it is more than 10% fragmented. I still do this occasionally, but Windows seems to be doing a better job of keeping things optimized.

11) Add More RAM Memory

There are a few physical things you can do to increase your performance, as well. You can and should add more RAM memory until the computer is at capacity. I’ve found that as a machine ages, you can extend its utility with a RAM upgrade. I’m literally ordering RAM for one of my laptops as I write this.

In most cases, this is simply a matter of snapping in or out memory sticks. Laptops are usually slightly more tricky and you have to remove screws, but still fairly easy. You can also have a retail store service desk do it.

12) Upgrade To An SSD Drive

Finally, you can upgrade to an SSD drive. This will make your computer run faster, but they are more expensive and have overall less storage capacity. I wish there were easy ways to convert standard laptop drives to SSD, but I haven’t found any that are affordable.

Do not let a slow machine stop your productivity. Use these tips on how to increase computer speed to keep your desktop and laptop machines running smoothly.

HOW TO RECOVER DELETED FILES IN YOUR PC

Check the Recycle Bin

Windows stores “deleted” files here as a safety measure. You’ll find the icon in the upper-left corner of your screen. if you find the files there, select them, right-click them, and choose Restore.

Use your backup

If you back up your hard drive—or at least your libraries—on a regular basis, your files are probably preserved there. I don’t know which backup program you use, so I can’t tell you exactly how to search for and recover the files. It’s generally a pretty intuitive process.

And if you don’t back up, maybe it’s time to get into the habit. It won’t help you this time, but it could the next.

Try file recovery software

Even a file that’s no longer in the Recycle Bin may still exist. Windows doesn’t overwrite the actual ones and zeros until another file needs the drive space. That’s why I told you to avoid using the PC as much as possible.

There are several good file recovery programs available. I recommend Recuva Portable. It’s easy to use and has a very good track record. And it sometimes shows you the images that it can recover. (I’ve seen it recover images that it could not preview.) It’s also free.

And, since it’s portable, which means that you don’t have to install it, you can use it on your PC without writing to the hard drive. Download the program on another computer, and unzip it to a folder on a flash drive. Then plug the flash drive into the PC with the missing files, and run it from there.

Hire a professional

This is the last resort, if none of the above suggestions work. There are many data recovery services available, and since your drive is still working, you probably don’t need one of the more expensive ones.
