Audio is a big part of our everyday lives. People use it whenever they need to talk to someone else using phone or computers. According to study, most comfort women nowadays use video call using their computers but issues on the sounds of computers are regularly because of various reasons, which is being the reason why some client get disappointed. There are a few ways for diagnosing, resolving and determining the loss of sound on a computer system. Materials needed are driver and application recovery CDs and updated sound driver software.Make certain that all the output devices such as headphones or speakers are turned on and plugged in. Additionally, be sure to check whether the output device has not been put on mute. Also, check the volume control settings of the program. Make sure that it is set high enough to be heard by the user. Always verify that the sound issues are not because of faulty speaker connections. The simplest way to test this is substituting speaker connections with headphones to check if the sound is getting out. The volume control settings could be accessed by clicking on the ‘Start’ button followed by ‘All Programs’, ‘Accessories’, ‘Entertainment’, and lastly, ‘Volume Control’. You may also simply click on the speaker icon located on the System Tray. Check the settings of both the mute and volume. When the check boxes of mute have checks on them, uncheck them. If this still does not work, the sound problem may be caused by other factors. Performing System Restore is required when the sound from the speakers of the computer is audible and is suddenly lost. This is done by clicking on the ‘Start’ button and then the ‘All Programs’ button. Thereafter, click on the ‘Accessories’ button, ‘System tools’ and then ‘System Restore’. Lastly, users would have to finish the System Restore Wizard. If this does not work again, the problem may be due to something else. In order to resolve the sound problem, you may have to delete and reinstall the sound driver. The sound driver could be missing or is corrupted that is why it is not functioning properly. When this is done however, the menu of the restore utility will not be available. Begin the process of deletion and re-installation by clicking on the ‘Start’ button, then the ‘Control Panel‘ and ‘System’. What follows is the ‘Hardware’, the ‘Device Manager’ and lastly, the ‘Sound’, ‘Video’ and ‘Game Controllers’. Click on the sound device displayed on the Device Manager and then delete using the ‘Delete’ key of the keyboard. When prompted whether or not to continue with the deletion, click ‘OK’. Uninstall all the sound devices listed in this manner except the Legacy Audio Drivers and the Audio Codec. Restart the computer and reinstall the sound drivers that have been deleted by means of the Driver and Application Recovery CDs that had come with the Operating System.

Preventing Disk Space warning

Registry Editor

Sometimes, when you try to open the C: or D: drive in your computer, you will get a warning about low disk space. Even when you try to delete files, you may still get the same message. Here’s what to do.

  1.  Run the Registry Editor (REGEDIT.EXE)
  2. Open HKEY_CURRENT_USER\ Software\ Microsoft\ Windows\ CurrentVersion\ Policies\ Explorer.
  3. If it’s not there, create a DWORD value and call it NoLowDiskSpaceChecks.
  4. Double-click on NoLowDiskSpaceChecks, and enter the value 1, and press OK.
  5. Check the messages. It should be fine now.

This would disable the pop up messages saying you have Low Disk Space warning messages but would not really solve the main problem of you having low disk space. This is useful if you are constantly annoyed by the pop up message even if you delete some files and it still would not work. The 200 MB threshold is the line that Windows has drawn for optimal performance. Once you fall below this threshold your system automatically takes actions to maintain minimum performance capabilities.

Here’s a potential risk of running too low on hard drive space. When your Windows system runs out of physical RAM memory, it will try to create virtual memory by using a chunk of hard drive space. If there is not enough hard drive space available, your applications may fail, you may not be able to open large files, or your system may just fall down and go boom.

So instead of disabling the pop up messages it is still better to fix the problem that is already at hand.

Low Disk Space warning

Windows created the low disk space warning to alert computer users when their hard drive is running low on available disk space. Then you will see this on a fairly regular basis as your hard drive fills up is the Low Disk Space warning: “You are running out of disk space on Local Disk [drive]. To free space on this drive by deleting old or unnecessary files, click here.

Low Disk Space warning pop out message

Sometimes, you may just need to ignore or disable your Windows low disk space. But it is not so simple when the problem is on the C: drive. In order for your computer system to operate properly it needs a minimum amount of available disk space on the system drive.

When your available disk space falls under 80 MB, Windows delivers a stronger warning message, and then it starts to free up drive space by deleting previous System Restore points. This reduces the number of restore points you can select from to restore your computer if the hard drive is impaired or corrupted.

There are essentially two ways to fix this:

1. Cleanup tool – You can use disk cleanup tool to remove unnecessary programs or rubbish that eat up your disk space, which definitely could free up certain amount of disk space.

2. Extend your partition. You may use a free partition manager software to extend partition or to resize partition. This is the easy and efficient way. You can extend your partition as you wish and not need to worry about data loss.

Troubleshooting Audio Problems

Uninstalling Audio driver

A world without music would be really dull. Imagine working on a late night project and you don’t have anything to listen to. Sucks right?

If your computer abruptly refuses to play sound, try the following simple steps.

  1. First, reboot your computer.
  2. Ensure that the computer isn’t muted via hardware. Press any external mute buttons, confirm that the speakers are turned on, and turn the volume all the way up. Test by playing a song or using the Sound control panel (click the Sounds tab, select Asterisk, and click Test).
  3. If that doesn’t work, check Windows. Left-click the volume icon in the system tray and verify that the audio is not muted and is turned up.
  4. Right-click the volume icon and click Open Volume Mixer. Ensure that all options are on and turned up.
  5. Internal speakers still not working? Plug headphones into the audio jack and test again. If the headphones work, remove them to continue troubleshooting the internal speakers.
  6. Right-click the volume icon again and choose Playback devices. Confirm that your audio device has a green check mark next to it. Click Properties and make sure that ‘Use this device (enable)’ is selected.

If your sound still doesn’t work by this point, you may have a missing or corrupt driver for your audio controller.

  1. Uninstall the driver. Open the Device Manager, go to Sound, video and game controllers, select the audio controller, and press the Delete key.
  2. Reboot the system and allow Windows to reinstall the driver, which it should do automatically. If it doesn’t, download the driver from your PC maker’s site or audio card manufacturer’s site, and reinstall it manually.

Testing a Monitor

How to fix your monitor

Testing a monitor is one of the easier computer troubleshooting steps. By fully testing your monitor using a logical troubleshooting process, you can be confident that your monitor is or is not working properly and then take whatever action necessary to get back up and running.

Follow these easy troubleshooting steps to test your monitor.

  1. Check to make sure your monitor is on! Some monitors have more than one power button or switch – check to make sure they’re all switched on.
  2. Check for disconnected monitor power cable connections. Your monitor might be working fine and your only problem may be a loose or unplugged monitor power cable.
  3. Check for disconnected monitor data cable connections. Again, your monitor might be turning on without a problem but no information can get to it because the cable that connects your monitor to your computer is disconnected or loose.
  4. Turn the monitor’s brightness and contrast settings completely up. Your monitor might be showing information but you just can’t see it because these display settings are too dark.
  5. Test that your computer is working correctly by connecting a different monitor that you are certain is working properly to your PC. Your monitor may be working fine but your computer might not be sending information to it.
  6. Determine why your computer isn’t sending information to your monitor.
  7. Test your original monitor with a monitor data cable that you know is working.
  8. Replace the monitor

The last one should be the ultimatum if all the tests do not work. Monitors are fairly easy to fix so this should not be a worry.

Fixing the keyboard

 

Keyboards are essential

If your keyboard stopped working, there are a few things you can check to troubleshoot what the problem might be. Depending on the situation, you can try one of the following:

First you have to be able to determine two important factors in this troubleshooting equation.

Did it happen while you were typing, or did you notice it right after starting the computer up? Other than an extreme obvious situation like spilling water on the keyboard, answering this question is important to know as it will help you identify the problem.

Is it a USB keyboard, is it a wireless keyboard, or is it a regular PS/2 keyboard connection? – You have to be able to determine the kind of keyboard you use so you know what steps to follow in this troubleshooting equation.

There are different ways to fix the problem. You should know what type of keyboard you use first then work on it afterwards.

1. USB keyboard

2. Wireless keyboard

3. PS/2 keyboard

There are many ways to fix this and it all depends on which type of keyboard you are using. The main thing to check is the connection of the keyboard to the computer. If the computer and keyboard is connected right then check if any of the lights in the keyboard is on or not. This may indicate if it is working properly. If both fail then check the control panel under keyboards to see if the computer detects the keyboard or not. After that you may start working on fixing it depending on what type of keyboard you are using.

Maintaining A Keyboard

When you spend a few hours at the computer, the two things you will always subconsciously know how to use are the mouse and keyboard, which are easily the most significant peripherals one can use on a computer. The mouse generally doesn’t accumulate much dirt as there isn’t much space for it to get in to begin with it. They keyboard on the other hand isn’t so fortunate. Located centrally, the keyboard is more of a dust and grime magnet than most other computer parts are ever exposed to.

And that can be one of the most frustrating things to have to work with. When you’re sitting at the PC and are trying to write a paper but half the buttons on the keyboard are either sticky, missing a key cap or just down right not press-able.

Just how it is recommended to clean a PC up every now and then and perhaps breathe some new life into it by doing a fresh OS install, it is vital to keep a keyboard in tip top shape for all your daily typing needs.

There are a variety of ways to clean your keyboard, and in the end it’ll all depend on what kind of keyboard you use. The easiest way is to carefully remove the key caps and then get rid of all the hairs and other dirt that will have built up on the keyboard’s inner workings. Note that you should not actually take the keyboard apart, simply remove the key caps and do some dusting.

Firewall

One of the most dangerous places for a computer to be is actually the internet. With the amount of viruses and other malicious pieces of code out there, you can never be too safe. Naturally, your best bet at keeping yourself and your PC safe is to simply not go to the high risk websites that could try and inject a virus of a kind.

There are numerous lines of defense one can rely on to have a flawless and mostly safe and secure variety to choose from. The anti-virus programs are some of the most popular ones, and many are freely available to choose from.

A firewall is one of those lines of defense that work best in collaboration with a strong anti-virus program. The purpose of it is to monitor every in-and-out going connection to your computer and strictly monitor what a certain program might be attempting to do outside of its intended perimeters. What it can’t do is protect your perfectly – since for every operation happening you will have to grant access to programs. There is little protection from the harm that you have permitted to go through.

This is where the anti-virus comes in to make sure that your mistake of letting in a dangerous piece of code can only do limited amounts of damage or is quarantined to protect your sensitive files.

If a virus manages to get past both levels of security you have either given it the permission unintentionally or you have somehow managed to contract a high level virus. In this case, your best bet is to immediately back up files and proceed to wipe your system.

Back Ups

Let’s face it – in reality, there’s a good chance that something completely unexpected happens and everything goes absolutely wrong. This holds especially true for all things technology – quicker than you might think and you can find yourself with a broken computer that won’t even start up any more. Accidents can happen and you should be prepared for the worst, unless you fancy losing absolutely all your data and files.

Having a back-up is never a bad idea. Imagine your house was struck by lightning, your power circuits blow and your computer’s power unit gives out, killing the rest of the machine in the process. Now imagine you had a fresh back up just lying around – perhaps online, or a USB stick, and lo-and-behold you can restore the backed up files to a new computer without losing a single thing.

There are many different ways to make, store and use a back up. The most convenient way to make one is to use the tools Microsoft has already provided in the Windows programs. Using this tool you can create a back-up and specify what you want in it. For many, there is little point storing a lot of their random media files, so they might only back up sensitive documents and such.

Combine this with the currently excitable cloud technology and you have maximum comfort from your own home. What’s important though is to keep a regular schedule of backing the relevant data, or one might find themselves in the situation of being stuck with an old back up that lacks all the recent files.

Anti Virus

Viruses are everywhere. Unfortunately this is a fact we cannot do much about especially in the industry of computers. There is money to be made off of computer viruses by the less morally inclined in this world, and unless that changes, we will forever be plagued by the annoyance of viruses.

There are several forms of defense against the little nuggets of code that are so detrimental to your computer system. Of course your first line would be none other than common sense – if you want to avoid viruses at all costs, then stay away from online places wherein you might get one. This includes, and is not limited to, piracy sites, shady dating and adult content sites. Those, bloated with ads and such, will always put you at a likelier risk of contracting a malicious program that could damage your computer.

The next line of defense is an anti-virus program. These programs seek to protect your files from unwarranted access, which is essentially what a virus ultimately seeks to do. There are many decent programs out there to get for free that will aid you in your quest against the never-dying world of viruses. A good anti-virus program will scan your system for files it might have missed when they were downloaded and checks there for malicious code. You are then presented with a variety of choices which normally includes an attempt of removing the malicious program or putting it into quarantine. Some viruses are very stubborn and will require a significantly more involved procedure in getting rid of them.
