There are two types of Digital Cameras available today: Single-lens-reflex (SLR) and Point-and-Shoot. DSLR cameras tends to gave higher quality images, hence the price that can range from US$1000-US$3000. A decent Point-and-Shoot digital camera can give you almost the same quality pictures for under US$500.

With almost countless point-and-shoot digital compact cameras available on the market today, it seems an impossible task to find the right digital camera that will give you the absolute best quality images at an acceptable price tag. As such, I’ve compiled this article hoping to be able to give you some real-world tips on choosing the right digital point-and-shoot camera.

With over 10 years experience I’ve learned to look for these features in a point-and-shoot.

Focus: Since almost all point-and-shoot cameras rely on auto focus, this feature has to be of the highest standards. The software needs to be able to recognize the image in question and focus on the subject, not the background. Some point-and-shoot cameras require more manual intervention for this function to work properly, so I’d look for a digital camera with enhanced auto features. This brings me to the next important feature.

Auto Mode: The whole idea of a point-and-shoot camera is the ability to point the camera at the object in question and shoot high quality focused images without too much fuss. The Canon Powershot SX30 IS for ex. takes brilliant pictures, but requires the right manual settings. For me that kind of defeats the object.

Light Sensor: The size of the light sensor is important; the bigger, the better. After all, if the camera cannot correctly sense the incoming light then the pictures will be too dark, or too light. Photography relies heavily on light and no amount of Photoshop can beat a picture that was taken in the right light, with the right light settings.

Megapixels: More is not always better, but too little can be an obstacle. More megapixels can sometimes ad to noise and too little will give you a less than sharp image, especially in poor light. Personally, I would never go below 10 megapixels and found that 14MP is ideal. At 14 megapixels you strike a nice balance between noise and image clarity.

Zoom: Beware of digital zoom. In essence, you’re just cropping the picture. Rather go for optical zoom. Personally, I’d never go below 12x optical zoom or the pictures just appear too distant. Recently, Super-Zoom digital cameras have become more affordable going up to 36x optical zoom. Very important to have a good image stabilizer at these extremes or you’d never be able to take a clear picture.

A few other features are also important, but these ones are crucial. I came across 2 point-and-shoot cameras that has a lot of these features present, but is also affordable. The Canon PowerShot SX30 is and the Nikon Coolpix L120.

Has our neighbor won a free notebook PC? It seems so by his excited looks and the animated way he is discussing something with others. After waiting for a few days, the exact details reached me. That gentleman badly needed a free notebook PC and he had spent lots of time browsing the net for the same. I had never believed that these things were possible, but now, that the proof is before me, there is no way that I can ignore it too. Taking off some time on a Sunday afternoon, I visited him and asked him how he managed to get hold of such a beautiful portable computer.

He explained that, like the others, he too did not believe in these deals until his son told him that his friend’s father had won one of them too. This is what motivated our neighbor who went on to complete the rest of his story. He used to search the net for a hour daily, for the free notebook PC. After have noted down a number of possible contenders, he started short listing them, keeping just those websites that were of leading computer manufacturers. He had also observed that these manufacturers made special offers from time to time when they would give away a PC for free along with the purchase of another product.

The gentleman in question also needed a new air conditioner badly and when he saw that a free notebook PC was being offered with a new air conditioner, he booked the same immediately. The rest is history! What is the best part of this deal is that my neighbor also got a special discount on the package by exchanging his ld air conditioner. It seems that I finally have to purchase a fridge that I have been thinking about for quite some time.

Motherboard is a key component of the computer, plays a vital role in the the computer. If the board have problems and it will affect the entire PC computer system work. Here we take a look at the most common motherboard faults which during we use our computers.

Fault 1: no show boot

Computer boots no display, we need to check the BIOS. Motherboard BIOS store important data of the hardware, while BIOS is the more vulnerable part of the motherboard, easily be damaged, if damaged will cause the system to not run. This failure is usually because the motherboard BIOS damaged by CIH virus (of course not rule out motherboard failure resulting system can not run itself).In general, after the virus destroyed BIOS hard drive data will be lost. So we can detect the hard disk data to determine whether the good BIOS is damaged. If the hard disk data intact, so there are three reasons why no show boot phenomenon:

1. Because the motherboard has expansion slot or expansion card problems, Board did not respond to display when plug in expansion card, such as sound cards, etc.

2. the CPU frequency settings in the CMOS at motherboard Free wire jumper does not right, may also lead to no-show fault. In this regard, fault can be resolved as long as the clear CMOS. Clear CMOS jumper is in the vicinity of the Main Board of the lithium battery. The default location is usually 1,2 short, just change it to 2,3 short jump, a few seconds you can solve the problem. If users can not find the jumper of previous old board, just remove the battery, enter the CMOS settings to be displayed and boot off, then install the battery also reached the CMOS battery discharge purposes.

3. Motherboard does not recognize the memory, memory corruption or memory does not match will result in no show boot failure. Some of the old board more selective memory, Once plugged in the memory that the motherboard does not recognize, motherboard will not start, and even some motherboards do not give you any fault tips (tweet). Sometimes of course, to expand the memory to improve system performance, plugging different brands, types of memory can also cause such a failure occurs, so maintenance should pay more attention.

When the motherboard BIOS is damaged, we can plug in ISA card to see whether the display (if prompted, can suggest these steps.), If there is no boot screen, you can make a floppy disk automatically update your BIOS, refresh BIOS, but some motherboard BIOS is damaged, the floppy drive simply does not work, then, try to use hot-plug method to solve(I have tried, as long as the same BIOS, the motherboard in the same class can be successful write). But the use of hot-plug addition to need the same BIOS may damage some devices of the board, so a reliable method is to use a write code device to write the BIOS update file inside the BIOS.

Fault 2: CMOS settings can not be saved
Such failures are generally due to insufficient battery voltage of motherboard, which can be replaced to solve the problem, but some motherboards can not solve the same problem after changing the battery, then there are two possibilities:

1. Motherboard circuit problems, which should look for professional service;

2. Motherboard CMOS jumper problem, Sometimes because of incorrectly set the CMOS jumper on the motherboard clear option, or set to an external battery, making CMOS data can not be saved.

Fault 3: In Windows, after installing the motherboard CD-ROM driver, cause the phenomenon of crash or slow down read the disks.

In some no-name motherboard can sometimes be such a phenomenon. After installing the motherboard drivers, restart the computer can not enter the Windows 98 desktop, and that the driver under Windows 98 can not be uninstalled. If this occurs, it is recommended to re-find the latest drivers and installed, the problem can be solved generally, if it is not, can only re-install the system..

Fault 4: When installing Windows, or start the Windows mouse is not available

Reason for this failure of the software is generally caused due CMOS settings wrong. Power management settings in the CMOS field has a modem use IRQ project, his options were 3,4,5…, NA, generally it’s the default option is 3, set it to 3 items can break away.

Fault 5: Frequent computer crashes, freezes occur during the CMOS settings.

Phenomenon occurred in crashes in the CMOS, usually the motherboard or CPU problem, should the failure by the following method does not resolve, it can only replace the motherboard or CPU.

This failure was due to board Cache general problems or bad motherboard design heat, I had already found because of cooling is not good enough to result in the failure phenomenon in the 815EP motherboard. After the Death Touch CPU motherboard components around, and found that the temperature is very hot. After replacing the high-power fans, crash failures can be resolved. Cache problems for failure, we can enter the CMOS settings, you can be successful after the Cache ban, of course, Cache ban will definitely affect the rate.

Fault 6: board COM port or parallel port, IDE port failure

This failure is usually due to user hot plug related hardware. At this time user can use the multipurpose card to replace. However before replace must be prohibited the COM port and the parallel port on the motherboard (some motherboards with IDE port to be banned for proper use).
