Hard Drive Failures Are Commonly Misdiagnosed As Viruses Or Other Computer Repair Issues

Computer hard drive failures are the number one most misdiagnosed computer repair issue by home PC users and inexperienced computer service center technicians. By the time most people determine for themselves that their computers hard drive is failing, they have already lost much or all of their valuable data and are they're facing a costly and possibly unsuccessful data recovery job. Computer manufacturers such as Dell, Apple, Toshiba, HP and others contribute to this problem by often pre-installing a tool with which to test the hard disk drive that has been pre-configured with a very high threshold for reporting failures; possibly to avoid having to replace large numbers of drives under the computer or hard drives warranty.
What most commonly occurs is that a do-it-yourself computer user or inexperienced computer service center technician will notice that the computer is not responding correctly and all too often incorrectly diagnose the problem as being related to a virus or malware infection or other software problem, and will set about reinstalling the operating system and reloading the machine. This usually exacerbates the problem since in all but the worst cases the machine will actually run normally again, often for several months until the hard drive failure progresses to the next level, valuable data is lost and you again have a non-functional computer.
A qualified and competent computer service center or field service technician will use a series of computer hard disk diagnostic utilities however not all utilities are created equal and the best tools for testing hard drives are among the least user-friendly. A program called "SpinRite" is one of the best tools in the industry for detecting early signs of drive failure, provided the computer repair technician knows how to read the drives raw data fields. To perform the tests correctly the computer will also need to be booted up from the hard drive diagnostics CD itself as the best tools for testing hard drives cannot be installed directly within Windows if you want to get a correct reading from the drive.
By performing the drives diagnostic tests properly you can in most cases detect hard drive failures before any loss of data occurs and prevent the need for a costly and possibly unsuccessful data recovery job since most failing hard drives will show inconsistencies in the raw data fields long before any loss of data occurs. When choosing a computer service company to work on your computer it is of the utmost important to make sure that they actually perform a full set of diagnostic tests on both the computer's hardware and software systems and don't immediately resort to reloading the computer as is too often the case.

Common Computer Issues

They are many computer issues out there, in this article we will cover the main issues and how you can try to fix them.

Your computer doesn't switch on, this is commonly coursed by the plug or power leads not being plugged in properly. Plug them all in and see if it works, if not then the power supply unit maybe damaged or broken, see if installing another one fixes the issue.

Your computer is making strange noises, this normally means something inside your computer is going to fail and die, but some times this could just be a wire resting on one of your fans, take the side of the computer case and check any loose wires.

Your computer is running slow, there many reasons that could be to blame for this. The main reason is viruses and spyware, these two can create a lot of issues for any computer and will cause your computer to run slower then before. Other reasons can be failing component, this is not normally the case though, and you can try to install some more memory and also defragging your hard drive to see if there is any increase in speed.

Your monitor screen is fuzzy, make sure the connection to the video card to the monitor is connected correctly if the issue is still present then make sure you don't have any speakers or anything that is magnetised as this can damage the monitor.

There is a buzzing sound coming from your speakers, again like the monitor make sure the connections are fitted correctly if the buzzing continues then there maybe a issue with the grounding on the mother board, try connecting a ground point on the motherboard to the case and see if the buzzing stops, if not the speakers could be damaged.

You're running windows XP and your USB mouse and keyboard aren't working, this is because Windows XP is quite old now and you will have to install the drivers for most devices that use USB connect, this isn't the case with the newer operating systems. If after you've install the drivers and the mouse and/or keyboard still aren't working make sure the USB controller drivers for the motherboard are installed, and see if you can test the mouse or keyboard on another computer to ensure they are working.

You can't connect to the internet, they are many reasons this could be because the modem your connection to isn't connected correctly but if your connected wirelessly to a router then make sure your connection details are correct like the right password for wireless key. Also with most modern routers you can see if the router it's self is connected to the internet via the connections settings option.

Your hard drive is making a ticking noise, this is normally the sign that it's ready to fail or die, so backup all the data from it to be safe that all your information doesn't die with it. Some older hard drives sound like this but the new ones of today don't make that much noise at all.

Your computer keeps restarting it's self or crashing, they are many reasons for this but the most common one is over heating. If your computer or laptop is in a closed space or has a lot of components inside it they is a high chance that it will over heat, they are many ways to avoid over heating, the main one is to install extra fans inside your computer case, and the main way for a laptop is to place the laptop on a flat surface or get a laptop base that has fans in it to go underneath.

Troubleshooting a Computer or Laptop Problem

Unlike today's cars, our computers don't have an entire on board system that identifies problems within our machine. This means we need to manually troubleshoot every issue that pops up. Because of the numerous differences between hardware, software and operating systems, the process of identifying a computer issue can be challenging. To simplify this task, computer repair experts have developed flowcharts that attempt to identify problems with the computer or laptop by process of elimination. These methods can quickly and accurately pinpoint a problem with your computer.

Clients are taken aback when we ask them seemingly ridiculous questions like "does the computer turn on?" because they don't always appreciate the process by which we need to figure out what is wrong especially if we are diagnosing a computer problem over the phone. But these questions are necessary so that we can rule out possible causes. There's no point worrying about whether a computer has a virus problem if we can't even get it to power on.

The first step in troubleshooting a computer is to figure out if it is turning on or not. This means verifying that the power source is functional and that the cables are properly plugged in. From there, we need to monitor sounds and LEDs. Are the lights coming on like they should? Do you hear beeps? Is the fan spinning up? If all of these basic functions are starting up properly, then we can move on to verifying that the display elements are working properly. Otherwise, we're stuck doing board level diagnostics. If the lights are not coming on then there is a power issue. Even if a motherboard is faulty, the system lights should still turn on when the power button is pressed. Verify the integrity of the power environment before testing the power supply with a power supply tester.

If the computer is turning on but the system fan is not spinning, you will need to visit your computer's bios settings to make sure that the fan is set to spin. Failing that, you may have a faulty fan. The final sign of trouble is beeps or beep codes. These will alert you to various board level failures including memory and video failures. You will need to consult your computer's service manual to match the beep codes with the error message.

Once past this point, we can see if anything comes up on the screen. If there is no display and none of the previous trouble signs were active then there is a video failure to troubleshoot. For laptops, connect the unit to a desktop LCD screen to see if there is a display there. If yes, then you have a LCD issue. If not, then you have a video chip problem. However, if you have gotten this far without any of the aforementioned problems then you have pretty much narrowed down the problem to your hard drive.

As referenced in our other articles, hard drives are very prone to failure. There are both hardware and software issues that affect only your hard drive. Once your computer has booted up and you are passed the bios splash screen and component tests, your computer is looking for a boot device. This is usually your hard drive where your operating system is installed. If there is a hardware failure, you will probably get a error message similar to "No boot device found" or "missing Drive on..." At this point, you want to verify that the hard drive is properly connected to both the data cable (IDE or SATA) and the power rail from the power supply. If it is spinning but not detected, try replacing the data cable or reseating it. If it is not spinning, try to power it up via a different rail or with a different power source. If it fails to power on, then your hard drive has failed.

Finally, if you bypass all the aforementioned problems then your computer is probably fine on a hardware level. Now, it is time to see if there is a problem with Microsoft Windows. If the Windows loading screen with logo comes up then you know that your hardware and hard drive are all functioning well so far. If you fail to get passed the logo screen, you cannot login to windows once the user list is active or you receive a blue screen of death (BSOD) then there is operating system corruption. The resolution for these are numerous and complex. The most basic step to attempt is to pop in a recovery CD and try to either repair the Windows installation or restore the computer to an early save point when the problem was not occurring.

Operating system issues are caused for a number of reasons from the unavoidable update failures to malware and virus infections. At this point, you have properly identified at what level the computer is failing and you can begin looking for a resolution or contacting a computer repair shop!

Summer Slowdown Computer Maintenance Tips

If you're in the ice cream business, the summer may be your "hottest" season. But, many businesses seem to slow down over the summer--schools are out and many clients and employees are enjoying vacations and family time.

Smart business owners take advantage of this slowdown to set goals and review business strategies. It's also a great time to maintain your computer systems and review your technology needs for the year ahead.

Don't let the summer slowdown affect your computer too! Here are 7 tips to keep your Windows or Mac computer running at sizzling speeds in the fast lane:

1. Uninstall unused programs, and if you're a Mac user, uninstall unnecessary language files too! Another tip for Mac users: If you're using an Intel-based machine, remove the unused Power PC binaries, too. While it may seem obvious, we recom­mend that you double check that you really don't need these programs before removing, in particular, anything that looks like it might be system related.

2. Clean out your temp files, tem­porary Internet files and other junk files at least once a month. If you're a Windows user, don't forget to clean up that registry. Mac users, clear your cache. You might want to invest in some good third-party software to do these steps on your Windows and Mac machines.

3. Empty the trash! This applies to both Windows and Mac users alike.

4. Maintain at least 10-15% free disk space on both Windows and Mac platforms. The operating system needs room to maneuver-be sure to give your system the space it needs.

5. Clean out your email. If you must hang on to it, consider moving items to an archive folder or file.

6. Defragment your system. Newer Mac and Windows oper­ating systems (OS X and Windows 7) do not require this as much; however, if you're still using an older machine, you will see a performance benefit from defragmenting your hard disk.

7. Shutdown your machine regularly, don't just put it to sleep. Not only is it "green," it will perform a complete system reset and give your computer a burst of "energy."

Now that you've cleaned things up, keep it up! We recommend performing these routine mainte­nance tasks at least monthly-preferably weekly.

Don't let the lazy days of summer make you lazy too! Carpe diem... seize the day! Give IT Radix a call and we'll be happy to help you make the most of this summer's slowdown
