How to make your Computer Speedy?

There are several things you can do to increase the "speed" of your computer.

1) Clean up the disk. Uninstall unneeded programs (especially those that run at startup and/or put something in the system tray), run Disk Cleanup, and defragment the drive. This is a good first step that will almost always take a few seconds off boot time and application loads for any computer.

2) Stomp auto-starting programs. Click Start > Run and type "msconfig" at the prompt. Click the Startup tab and look at all that junk that loads when you launch your PC. Do you really need "Adobe Reader Speed Launch"? Probably not. Turn off anything else that looks useless, but be careful not to disable your anti-virus and important system components.

3) Run a full anti-virus and anti-spyware scan. I would recommend using AVG Free anti-virus, Malwarebytes and SUPERAntiSpyware remover. These programs are all free.

Some other ways

1) Upgrade RAM. This is the one killer trick that will make almost any computer run faster. With an older PC, you will rarely have enough RAM to run today's memory-hogging operating systems and applications, and adding a high-capacity stick or two of quality RAM will give you a quick speed boost. Adding RAM is fairly simple, even for a novice, and you should be able to do the job in 5 or 10 minutes.
2) Reinstall Windows. If the above tricks haven't helped, it may be time to wipe the slate clean and start again, reformatting your hard drive, reinstalling your applications, and restoring your data files from a backup. You'd be surprised how much more responsive a freshly reinstalled Windows system can be, as you've wiped out years of temp files, garbled registry entries, old versions of software programs that have been upgraded repeatedly, and all sorts of other electronic junk. Reinstalling is easy if you have the "recovery disk" that came with your PC, and only a bit more involved if you're using a retail copy of Windows XP. Just be sure you back up everything you want to take with you before you pull the trigger!

3) Upgrade your hard drive. This is a more complicated solution, but if you're reinstalling Windows (per the prior tip) you might consider upgrading to a bigger and possibly faster hard drive, too. Hard disk storage is a performance bottleneck on every machine, and magnetic disks degrade over time. Some performance issues could be caused by a failing hard drive, even, and upgrading to a new model could really put some zip back in your system. As a bonus, you can use the original hard drive for backups or occasional storage, if you put it in an enclosure.

What is Java?

2012-08-21T03:14:00.003-07:00

A search on 'What is Java' in google returns roughly about 329,000,000 pages. That is the popularity of Java on the web. If you haven't read the history of Java please read it first here. Java was just meant to be a portable, platform independent programming language. But over the years it has transformed into a complex platform for computing portable software across different devices and systems. What is the need for Java? When there were so many programming languages already available what was the need for another programming language. To understand this let us take an example of a program that runs on a SONY TV remote control. This program can be written using a language (let us assume) called X. The remote control has an in-built chip on which this program will run. If we look at the functionality of a TV remote it is almost the same for any brand of TV. So by right the same program should be used on any brand of TV remote. In reality it is not. Why? Because the in-built chip in different brand of TV Remotes maybe different. Therefore the same program has to run these two different chips, they have to be re-compiled in order to suit different chips in other words platforms. If there are 100 different brands, the same program has to be re-compiled 100 times to suit these 100 different brands. This is where the problem arises. That is why a new programming language was needed. And Java was the answer. How does Java solve this problem? The Java designers came out with a wonderful concept of a 'Java Virtual Machine'. Now Java differs from rest of the languages in using this unique concept. Which means unlike other languages a Java program when compiled produces a ByteCode rather than machine code. This ByteCode is machine independant (platform independant). The Java Virtual Machine resides on the machine and interprets this ByteCode into a form the machine can understand. Now take the same example of a TV remote. If the program was developed using Java rather than X, then the same program can be used in all different brand of TV Remotes provided all of them have the 'Java Virtual Machine' (JVM) installed on them. If all of them have the JVM the JVM will convert this same program into a form that each brand of TV remote understands. This is a very simple but effective method of making a program portable. This is how Java solves this problem.

How to assign or change a drive letter in your hard disk?

2012-08-20T13:26:00.002-07:00

While assembling a computer, usually drive C attains main role and others become subsidiary, while using pen drives the OS automatically assigns an alphabet and later delete it. Do you know you can assign a name using A to Z alphabets? Disk Management snap in software in windows XP provides this feature. A and B letters are assigned for your floppy drive C is assigned disk containing OS. If you don’t have floppy drive you can use A and B for other drives. But you may install floppy drives some day so we will leave out A and B and see how to assign other alphabets.

To assign all favorite letters to a disk drive (or) part of (or) a volume for the first time do as said below. First start log in as user.

What is Downloading, Uploading Installing and Un-Installing

2012-08-20T13:24:00.002-07:00

Downloading, Uploading, Installing and Un installing are most favorite words in the usage of computer and Internet. Let’s see about this.

Downloading:

We are copying a file from a network or an Internet to our computer is called downloading. We need not to do so much work for this. In Internet it displays, if you want this facility click here to download. If we click the link it will ask the place to store the file then we select the directory. The file will start to download. It shows the message it contain the rate and time.

Uploading:

This is the reverse process of downloading. That is we can copy the files from can computer to a network or the Internet. Generally the process is run by F.T.P. some of the Internet website provide the way to upload the files through their browsers.

Installing:

Mostly the peoples confuse both downloading and installing. Installing means process of our computer is preparing for run a program. Generally its have a setup program to run when we are executing the setup program it ask some questions. We give to answer for this questions then it start copy the files to your computer for run the particular program. If we want to run the program we may click the icons in the desktop. Otherwise select the program from star/program menu.

Un Installing:

This is also the reverse process of installing while installing the program. It will copy the files in your computer. When we don’t want the program it’s hard task find and delete the files. Because of that the developers are create one exe file for uninstalling with that program.

We can see the file in program directory. Otherwise we can uninstall the file by select the Add/Remove Program option in control panel. Here all the installed programs are arranged in alphabetical order. We can select the program from the list, which is wanted to uninstall.

Computer Crash reasons

2012-08-20T13:22:00.003-07:00

You may have heard of the ‘Blue Screen of Death’ but haven’t experienced it yourself. It is better to know the reasons behind this crash so that when it happens you are in a position to fix it. If you see on the screen “Fatal error: the system has become unstable or is busy”, “enter to return to Windows or press Control+Alt+Delete to restart your computer. If you do this you will lose any unsaved information in all open applications”. This is the infamous blue screen of death. This could happen due to any of these following reasons:
Hardware Problem: Computer consists of different hardware such as Printer, mouse, flash drive etc. Windows assigns an IRQ number for each of these hardware. When due to some reasons more than one hardware use the same IRQ this will result in a crash. In order to find if you have any hardware conflicts you can goto the ‘Device Manager’ in your computer properties. (Start-Settings->Control Panel –> System->Device manager), an yellow exclamation mark will be placed against the hardware that has a conflict. You can resolve this by selecting the device, uninstalling and reinstalling it again.
RAM memory: When you upgrade RAM memory, if you have two unmatched RAM cards or a RAM card that is not compatible with your motherboard, then a “Fatal Exception Error” will occur when you start the computer. If you are technically savvy then you may try to fix this by going to BIOS settings and editing the ‘Wait state’ of RAM or you can replace the cards with the same speed and capacity.
Hard Disk Drive: After using the computer for a few months or years, the hard disk gets fragmented with temporary files, or fragmented files. This will result in slowness of hard disk and may even result in computer crash eventually. You can maintain your harddisk by defragmenting your hard disk frequently and deleting unwanted files.
Video Card: If you see “Fatal OE exceptions and VXD errors” then it is due to the video card. To solve this reduce the video display resolution. You can do so by going to the control panel and display settings. Choose the correct screen resolution to match your monitor and change the color settings to 16 bit or match it with your monitor.
Virus: Most of the computer crash is due to Virus infection in your computer. You should install or enable windows firewall and install an Anti virus application to prevent unwanted virus applications infecting your computer.
Printer: Sometimes you may notice that the computer crashes whenever you try to print something. This is due to low memory buffer in the printer. Therefore when you send a lot of data to the printer or if you have multiple applications open and you print at the same time, this may happen. Unplug the printer from power outlet for 10 minutes and connect back again. Close other programs and try to print again.
Software: If a particular software is not installed properly or is not complete then it may result in a crash when you try to start that software. You have to uninstall such software properly. Otherwise some entries may still be in the registry referring to that software and result in instability of the computer. You can use registry cleaning software to clean your registries frequently.
Heat: Computers have inbuilt fans to cool down the processors. You can control the CPU speed from your BIOS settings. If the speed is set to higher than the normal CPU speed, this may result in overheating of the CPU which will result in Kernel Error.
Power Supply: Use UPS to regulate the power supply to your computer. This will reduce the chances of your computer crashing.

A tutorial on msconfig – System Configuration

2012-08-20T13:20:00.004-07:00

msconfig is the Microsoft System Configuration Utility. In Windows Vista and Windows 7 it is called as ‘System Configuration’. This is a tool that comes with the Windows Operating System. For Windows 2000 users this tool can be downloaded from microsoft website. This is used to configure and maintain your Windows System. In this tutorial we can see how to use this tool.

To start this tool goto Start->Run and type ‘msconfig’. A new window with five tabs will open.
General Tab: This tab has three sections. Normal Startup, Diagnostic Startup and Selective Startup. When Windows functions normally we use Normal Startup. When the system doesnt function properly, we can use diagnostic startup to diagnose the issue and to troubleshoot. If we want windows to start with specific programs then we can choose Selective Startup.
Boot Tab: This tab shows the operating systems installed in the computer. Additionally we can choose options such as ‘safe Boot’, ‘Boot log’, ‘Time out delay’. If you are a new PC user then it is best to leave this tab without any changes.
Services Tab: This tab lists all the services installed in this PC with the details such as whether the service is running or stopped etc. From here you can enable or disable services. You can check the ‘Hide all Microsoft services’, to hide all essential windows services so that you don’t change them by mistake. From here you can identify unknown services that take up your memory and stop them wherever necessary.
Startup Tab: Startup tab shows the list of programs that starts automatically when Windows starts. All system tray programs and programs that run in background will also be listed here. You can see which of these services and programs you don’t need at startup and remove them accordingly. This will speed up your windows startup time.
Tools Tab: In the tools tab you can see, System Information, Programs, System Restore etc.

Adjusting Windows Task bar size: In Windows 7

2012-08-20T13:20:00.000-07:00

In Windows 7, the usual size of the Windows Taskbar is a bit larger than usual. This takes some extra space at the bottom of the computer screen. This makes selecting the applications easier as the buttons are bigger. However for those who are using smaller screens this may be a bit annoying as it takes more space on the screen. If you want you can make the size of the taskbar smaller by following the steps below.
In a blank space in the taskbar right click and select properties.
You will see the ‘Taskbar and Start Menu Properties’ dialog box with many tabs.
Here click ‘Use small icons’ and select it.
Now click OK and close the dialog box.

Now the task bar will occupy smaller space. If you want you can also hide the task bar when not required. If you want to hide the task bar, in step 2 above, select the ‘Taskbar’tab, and in ‘Taskbar appearance’, select ‘Autohide the taskbar’. If you choose this, if you bring the mouse to the bottom of the screen the taskbar will appear and if you move away from the task bar, it will be hidden.
