• Update your anti-virus scan and anti-spyware definitions, if they aren’t being done automatically.
• Back up any critical files that you have changed today to your flash drive.

Weekly computer maintenance tips:

• Make sure your anti-virus and anti-spyware programs have been updated with the latest definitions, and run a full scan from both programs.
• Reboot your computer. (If you shutdown your computer each night, disregard this tip). If you leave your computer on all the time, definitely do this. It will reset the RAM, and your computer will run much better and faster.

General Computer Maintenance Tips:

• Keep all of your working files in one folder. The My Documents folder is offered by Windows expressly for this purpose. The benefits of keeping all your files in one place are multiple. One, you know where all your files are, two, it's easy to back them all up at once, and three, your machine will run faster.
• Don't put your personal files on the root of the C: drive. If you store a large number of files in the root folder, you could corrupt your disk file table which could lead to a "NTLDR is missing" error message when you boot the computer. Very bad. If you have personal files on the C: drive now, move them to the My Documents folder.

Won't turn on

This is always a very worrying one. Going to switch on your computer only for nothing to happy is never a good sign. This will be a hardware issue and will usually be serious. If - after switching the computer on - there's no sound at all (i.e. nothing inside the system tries to start-up), this might be a fault with the power supply unit, CPU or in the best-case scenario a loose connection.
If you hear some sounds but then it fails, it might be a problem with the hard-drive or a couple of other components. Either way, in this case it's usually best to contact your computer vendor or local repair shop straight away and go from there. There's unfortunately very little you can do unless it's a loose connection (however it's unfortunately rarely a loose connection in these cases) hence it's best to ring up your vendor/repair shop.

Strange Noises or Vibrations

This is caused by a hardware issue. Sometimes it's (thankfully!) something minor such as a slightly loose connection or a loose screw (loose screws = loose components = vibrations, especially when it comes to CD/DVD drives) which can easily be solved without the need to hire a computer technician (although if you aren't comfortable with the internals of a system, then call a repair person nonetheless).
If it's not caused by a loose connection or screw, it might be the sign of a more major problem: hardware failure. In this case, one of your computer's components will probably have to be replaced.

Lockups, freezes and the 'blue screen of death'

If your computer freezes or locks-up, firstly try all of the above steps (see problem 1). If this doesn't help, then try updating your device drivers on the system. Check your computer's manual for instructions on how to do this if applicable. Also check to see whether your system is running low on disk-space or memory (RAM).
If none of the above help, your computer might have a hardware fault. A failing hard-drive could be one cause (a bad hard-drive will cause frequent lockups and freezes). In this case, contact your computer vendor (or the local repair shop if your computer's not under warranty) and go from there.

Chicken Came Before The Egg..!!!!!!!

It's the age-old question that has puzzled the finest minds for thousands of years -- which came first: The chicken or the egg? Now, scientists claim to have finally discovered the answer to the conundrum -- it's the chicken which came first.

team from University of Sheffield and University of Warwick has found that a protein called ovocleidin (OC-17) is crucial in the formation of eggshells.

The First Laptop!!

Pictured here is one of the first “portable” computers. It could be considered the first laptop. This is the Osborne 1, which came out in 1981. The computer cost $1,800, weighed 25 pounds, and had a 5 inch screen.

Choosing An Internet Service

For many Internet users, faster is always better, but for casual Internet users, price is the main determining factor when it comes to choosing an Internet Service Provider (ISP). Listed below is a quick overview of the primary needs and uses for the main forms of residential Internet access:
Dial Up
Casual use (checking email, instant messages, light Web surfing).
Accelerated Dial Up
Casual Internet users that surf the Web on a regular basis and download large files more often. Netzero and PeoplePC are the most popular ISP’s that offer an accelerated dial up Internet service.
DSL or Cable
Regular Internet use (email, IM’s, surfing), online gaming, streaming music & video, and large file downloads. Verizon and AT&T are the primary high speed DSL providers with entry level plans starting around $20 per month for up to 768 Kbps download speeds. Comcast and Time Warner are the main broadband Cable providers. Although cable is faster than DSL in most areas, it is also going to be a little bit more expensive. For a full comparison of the two, check our DSL vs Cable article.

Satellite
 
As this is the most expensive option for high speed Internet, it is mainly used in areas where cable or DSL are not yet available.

Wireless
 
Mobile users that need a high speed connection to the Internet while away from home or out of the office.

Computer Power Supply Knowledge

 

A Computer Power Supply (PSU) is vital to the operation of a computer. The Power Supply converts AC current to DC current and then sends power to all of the internal components in the computer system so they can function.

Will Turning Off Your Computer Will Protect it From Power Surges

 “It is enough that you turn off you computer during thunder storms, in order to protect it from power surges.”

This statement can be very misleading. Turning off your computer is an important key in avoiding power surges caused by bad weather. But in addition to turning off your unit, you also need to unplug all of your computer hardware.

Three Signs of a Malfunctioning Computer Power Supply

A malfunctioning power supply can seriously damage your computer. When your computer power supply starts acting weird, you need to replace it immediately or you risk destroying your whole computer system. Here are three signs that can alert you of a malfunctioning computer power supply:

How to Clean Your Notebook/Laptop Computer Keyboard

Laptop computers are bombarded with plenty of dust and dirt if you take them out with you often. Dirt and grime love to accumulate around and in between your laptop keyboard keys. If you want your laptop to be free from dust and germs, you need to clean the keyboard.

LCD Vs CRT

When computers were first introduced, they only came with one type of monitor: the cathode ray tube (CRT). Decades ago, however, another type of computer monitor emerged: the liquid crystal display (LCD).
Which display unit is better: an LCD or a CRT? Both technologies actually have disadvantages and advantages. Here are some of them.


* Display Sharpness
One very important thing to consider when buying a computer monitor is the screen resolution. The higher the resolution, the clearer the images you see on your computer screen. You do not want a monitor with a low resolution. It will display very poor images.
LCDs generally display sharper and clearer images than CRTs. They have a native screen resolution at which they perform best. On the other hand, CRTs are not limited by a native screen resolution and can perform equally well at all their supported resolutions.

Keeping Your Computer Cool: Three Things to Avoid

If you run your computer hard and fast, you will eventually experience overheating problems. Overly busy computer components give off more heat than those that are running fewer processes. Overheating issues can be minimized if you avoid these three commonplace scenarios which aggravate the buildup of heat within your computer system.


* Blocked Air Vents


Do not block the air vents around your computer case. Air is as important for us humans as it is for computers. Hot computer components need properly circulated air to cool off faster. To promote the exchange of air between your system and the outside environment, avoid pressing your computer case against the wall or stacking books and papers beside your case. Keep the air vents fully exposed so your computer can breathe without difficulty.


* Unnecessary Applications


Do not run unnecessary software applications. Managing too many programs causes your computer components to work harder and give off more heat. Close the applications that you do not need and simply run those that require your immediate attention. You will not be able to work on more than two or three applications at a time anyway. Computers need a break too.


* Overclocking


Avoid pushing your central processing unit (CPU) beyond its specified clock rate to boost your computer’s performance. An overclocked CPU gives off a lot of heat and you will need to employ advanced cooling solutions to keep your CPU from melting. If you really need a faster computer, do not push your CPU to its limits. Instead, buy a faster CPU or increase your random access memory (RAM). Note that overclocking your CPU will shorten its lifespan and void its warranty.

How to convert older Office documents to Office 2007 format?

The Office 2007 applications such as Word and Excel can open a spreadsheet or a document which is in an older edition of Office.  They can open such older version documents in Compatibility Mode. However, if you need to make use of various newer features available in Office 2007, you will have to convert older Office documents to Office 2007 format.

How to Disk Cleanup In Windows7

You might wonder: Why Windows keeps those files if they're not necessary? "Temporary Internet Files", for example, everytime you browse to a webpage, your web browser requests the contents from the host, saves them locally as cache, then displays the contents to your browser window. Now, to speed up the access time when you come back to the same page, your web browser might re-use those cache files if they're not changed from the webpage.
"Temporary Internet Files" are just one example of the temporary files you can clean up. Follow the steps below to clean up other temporary sources as well.
Most likely, temporary files are stored in the Operating System drive ("C Drive"), but it doesn't hurt to do a cleanup all of your hard drives every once in awhile.
Use this trick at your own risks
1.    Launch the Disk Cleanup utility by either:
    - "Start" >> "Programs" >> "Accessories" >> "System Tools" >> "Disk Cleanup", or:
    - "Start" >> "Run", enter "cleanmgr" then press Enter.

Hide Files or Folders Using Command Prompt

    (To view this folder again, use the same command but replace '+' with '-' on both flags 's' and 'h')

Burn a CD/DVD on Windows 7 or Vista without using software (Detail)

1. Insert a blank recordable/rewritable CD (CD-R) or DVD (DVD-R/RW, DVD+R/RW) disc into the CD burner drive.
2. With a new blank disc, Windows might pop up a prompt asking you which format you want to use (as shown on the image below).As explained on the popup, the option "Like a USB Flash Drive" is more convenient if you want to use the disc as an external storage, which you can add or delete (rewritable disc) files on the fly; however, once the disc is formatted with this option, it can only be read on computers with Windows XP or later. On the other hand, the option "With a CD/DVD Player" is the traditional format of CD/DVD disc and is compatible with a wider range of Windows versions as well as other devices, but requires to burn the disc (or erase the entire disc) all at once.

How to disable CHKDSK ERROR at booting time

Click on Start then Run , type cmd and press Enter . Next type fsutil dirty query x: where x: is your boot drive. This queries the drive, and more than likely it will tell you that it is dirty.

Next, type chkntfs /x c: . The X tells Windows to NOT check that particular drive on the next reboot. Now manually reboot your computer, it should not do a chkdsk and should take you directly to normal Windows login.

Once Windows has fully loaded, bring up another Command Prompt and enter chkdsk c: /r . Reply Y when asked if you want this to happen on the next boot. This should take you through 5 stages of the chkdsk scan and will unset that dirty bit. This can take an hour or more depending on the size of your hard drive, be patient and let it complete.

Once booted back to Windows, open another Command Prompt and query the dirty bit again by entering fsutil dirty query c: and Windows will confirm that the dirty bit is not set on that drive.
