Getting the best deals on electronic gadgets is fairly easy if you know when to buy them. Yes, you can actually get some good bargains when you buy electronic items at a time their prices are at their lowest. You are probably asking, “Is there a particular time of the year when they actually lower prices for PCs and tablets?” In fact they do!

Believe it or not, certain tech items have particular “seasons”, and buying when they are in season may just put you well above your spending limits. Knowing when this “season” goes out would be the opportune time for you to buy them. When some people would just delay purchasing an electronic unit in hope of the item’s price going down, the practical buyer would gladly wait till he can get a bargain. Of course, delaying a purchase in anticipation of scoring a better deal out of it seems pointless as most items would simply cost less in six months. Well, it goes for almost anything actually. You could sometimes wait for a year and you might get an obsolete or even phased-out model. This is perhaps one of the downfalls of investing on electronic gadgets – because they are seasonal, buying an item at a later time might just lead you to owning an outdated model. Then again, if you are practical, that’s besides the point.

When prices of commodities tend to soar, electronic gadgets are not as well spared from this. What is important to consider is that there is a specific season when to buy these gadgets at very low prices that they might even be given for free. Take a look at these particulars:

  • Digital cameras can be had at low prices during the middle of the year. Although they can go on sale starting February when the Consumer Electronics Show in January is concluded, it is best to get a digital camera around June and July. You might even have a handful of uses for it during this season.
  • Mid-year is also the best season to get a new computer unit. Most computer companies – like AMD and Intel – ramp up supplies and stocks in July, so they tend to dispose of many other gadgets in the market during this time. And not only that, the back-to-school sales are just as good as any. (Just a thought – there was one article published a few months ago which says computers and laptops as well as other electronics are usually at their lowest prices on Monday because this is the time where most manufacturers apply rebates. The real score is that it is not true. In fact it doesn’t make a lot of sense at all.)
  • HD televisions can also be purchased at great prices in summer. The reason being that most HDTV models were released in the market in 2012. This just means the ones available now are for a lesser price than those sold in 2012. Most units can even go down on prices during the holidays with more than 40 per cent discounts on premium items.
  • Tablets are also a great buy this year. Prompting the release of many models last year, prices for tablets and even iPads have gone down in 2014 owing to newer models being readied for the market before the year ends.
  • Smart phones – android and other units except iPhones – are fairly good items to buy during summer because many products from phone companies are always producing in excess of demand. The same goes for e-reader and Evergreen. Most of these companies do not come up with newer updates in two years time. iPhones can be a good buy if they are past their prime.
  • Take into consideration that Black Fridays have discounts on computers and electronics but can also spell disaster if you happen to go to those particular shops on foot when the sale goes on. Take great care beyond your guard if you chance this.

So there you have it. Knowing what season and when is the best time to buy electronics makes it more practical for you to own one without actually hurting your pocket.

If price is your primary concern, you can also check refurbished items as they can be had for a much lesser cost. If you are not bothered at all of owning an electronic gadget which is a model that could be a bit older, then you can go ahead and take note and follow these simple tips. You might be surprised at how much you can actually save.

With them, you can easily play high resolution games with no any glitches.

Those individuals, who remain stuck to computer games often like to indulge themselves in high end games. So, such enthusiasts prefer a gaming notebook to ordinary laptop. Nevertheless, what may prevent them from purchasing a high spec laptop is their budget. Many gaming notebooks are very expensive so you cannot afford a laptop. Nevertheless, if you search extensively on the concerned web, then you will get some notebooks with low specs but they are good for playing many computer games.

Below, two laptops which are fit for your gaming are being explained (please be advised as when this article is published, the models may not be the same and their prices may have gone down as newer models of gaming laptops are released):

Toshiba Satellite Pro L670 -14L

It is a cool laptop which remains available for 900 dollars. When you take a glance at it, you will be fascinated with its aesthetics. This laptop is empowered with Windows 7 OS and Intel Core i3-350M processor. The engine of Mobile Intel HD graphics will provide you the best gaming experience since it features energetically allocated gaming memory of 64MB to 1696MB. The measurement of HD+ TruBrite LED Backlit display is 17.3 inches. Its 6 cell Li-Ion battery proffers greater than 4.50 hours of battery.

Acer Aspire 5741G

Acer Aspire 5741 G, whose price is $850, is available with Intel Core i5-430 processor. It features two RAM slots on this system and you can load about 4GB of DD3 RAM. Also, you can choose from 320GB to 640GB hard disk. As far as gaming is concerned, you are proffered with two types of graphics controller. They are ATI Mobility Radeon HD 5470 and NVIDIA GeForce GT 320M. Furthermore, it features a graphics memory of 512MB on ATI and 1GB on Nvidia. It features a screen size of 15.6 inches and the weight of entire system is 2.5kgs. Its 6 cell Li-Ion battery provides a battery backup of about 4 hours.

So, this was all about different kinds of laptops, which you should buy for gaming purposes.

Hard drives both exists inside your desktop and laptop. This device holds software, movies, music, documents etc. Nowadays, it is more advanced in comparison to those ones, which existed many years back. At present time, these drives are of smaller size and have a greater capacity. These devices spin very fast inside. Usually, these drives fail to last for longer periods as they did many years back; they simply last for three to five years. Habits of good backup are pertinent. There are lots of options for supporting your data.

It is pertinent for you to remain fully aware of the signs of hard drive failure as soon as it starts. There are certain warnings, which your computer will provide you. For instance, as soon as you start your computer, you may get to perceive a message associated with ‘SMART.’ It is peculiar type of technology, which this hard drive possesses and conveys to the computer that there persists a problem with the hard drive. Then, your computer will inform you on screen.

In case, you perceive a message other than ‘smart status ok’ for instance, then it is time for you to ensure that you receive your data backed up in another place and have replacement of your drive at the earliest. You may also get warnings associated with this as soon as the computer is in Windows. Remember that you should not avoid such messages.

Another important sign of hard drive making clicking noise is squealing sounds. It is worth remembering that it is mostly metal inside the hard drive. Therefore, if the drive is going to fail, then it can make very loud screeching noises. Usually, hard drives can make clicking noises which are normal, but if you start to hear humming, odd-timed, abnormal clicking or any other combined noises, particularly the squealing type, then you need to get your data backed up at once and then have the replacement of the drive.

In case, you are doubtful about its noise for instance if is quiet or simply clicking type noises, then you may think of recording the noise and then posting it to a video or media site and grill people about what it is really. You may also contact local technician. In any case, you should be sure to support your data.

Another fact to consider is if you happen to get a BSOD (the infamous Blue Screen of Death); it happens to be on the hard drives cycle. Remember that the disk spins cycling data and you may get an error message pertaining to one. Do not ignore this and consider what may have caused it before as to try and save your hard drive.

So, this was all about what you can do about clicking noise of hard drive. Go through this article with an apt attention to know everything in detail.

A computer is a simple machine we see and is part of our daily lives. How does it work would be the common question especially to the young individuals. Rich graphic designs which they enjoy as they play fascinate not only the kids but the adults who are still young at heart as well.

What makes these pictures come to life then? A graphic card is the one responsible for the 2D animations that each and every one of us enjoys today. Not only in the games that our children play but as well as viewing photos that come from all sorts. Graphic components are part of a computer that regulate and improve the display in the computer of the graphics which may be classified as the following:

  1. Videos
  2. Animation
  3. 3D
  4. Programs
  5. Pictures

Most often than not a graphic part is plugged in a detached card that is inserted into the main part of the computer called motherboard. This is the reason why normally a graphic component is referred by many as a graphic card. There are also instances wherein a graphic card is custom built directly into the motherboard.

Below are some of the names used for a Graphic Card

  1. Video card
  2. Display Adapter
  3. Graphic Accelerator
  4. Video Adapter

Graphic Adapters will not function without the platform that controls how the graphic component function with the rest of the computer such as the monitor, software etc. hence; the term Graphics Driver.

Similar to that of a television built with 110V, it cannot be plugged to a 220v electric current otherwise it will ruin the appliance or a television model manufactured in the 70’s will not work properly with the Play Station 2 or an Xbox that is commonly played today. Moreover, an iPhone cannot be recharged over a Samsung charger, simply put a key won’t work if it is not matching with the key hole.

The same principle applies with how a computer works. A lot of things can actually happen with the driver. It can either cause a trouble between other computer parts. A video card may be the reason for a sound card not to work properly moreover, completely stop working. There are instances where you may experience a lot of bugs which is usual to most of the software as it needs to be updated on a regular basis so you can get the best out of the device it control. Furthermore, the reason is that there are figuratively thousands of pieces of different hardware in use in just one computer. It can really be tedious and difficult for a typical user to find and locate the correct driver for the system. These are the challenges that ATI Radeon Graphic Card Drivers along with its Download Utility claim to resolve hence; the creation of the all-in-one solution device to enable your drivers to be up to date avoiding any conflicts.

These are some of the benefits you will get from ATI Radeon Graphic Card Driver Download Utility:

  1. Faster Internet Connection and Speed of up to 5 times
  2. Drivers are always up to date hence; better PC performance
  3. ATI Radeon device will surely run smoothly

If you get to face an error as soon as you put in your disc to the console and it fails to read them or denies to do anything or provides you a message saying ‘insert game disc’ then you need to think of way to have this fixed. “Why is my DVD drive not reading disc” is being answered suitably in this article below.

Many people think that when such problem happens, it is the DVD which is faulty. But, many times, it has got nothing to do with the DVD drive. This problem crops up because the receptors, which are present on the rear of the DVD, overheat and when they absorb more heat, it prevents the DVD from working in a proper way. Usually, there is insufficient heat to damage the DVD drive since it will shut off before that thing takes place. What you need to do is prevent the heat from building up and your DVD drive will start reading the discs.

Now the question arises, what you should do to prevent the heat from building up? Well, you send it to Microsoft and they will carry out fixing working for you. Nevertheless, you waiting time may be frustrating for you with many repair works taking some weeks or even more.

2014-08-09-048Quite frankly, a number of people take a negative stride when you mention the word “refurbished”. To them, refurbished may mean the product is a hand-me-down, nothing short of a second-rate object that may as well be defective or broken. The truth, however, is that a refurbished object is not broken or faulty. It means that the product is returned to the manufacturer for an assortment of reasons and then, going through some really intensive routines, is processed for a remanufacturing. This means that it went through the same process as all other new products would normally go through.

Should I Buy a Refurbished Desktop?

Gadgets and electronic appliances are usually subject to such a process. Unlike cars, an electronic gadget is refurbished without much consideration for changing a lot of its contents or internal function. For instance, when you sell a car, the odometer will tell you exactly the distance traveled. And it’s pretty much like telling your buyers how much mileage has been used. A PC or a desktop does not tell you a lot. Sure, you can change the mouse and the keyboard, or have the drive cleaned up and the operating system re-installed (if necessary) and the unit will still be almost like brand new, barring any broken or faulty pieces, of course. Regardless, a refurbished PC or laptop is still a good buy. Here are some reasons why:

  • Refurbished products often have the best price for the best quality. A desktop which has been returned and refurbished are mostly in mint condition and works well enough like a brand new unit. It may have been returned because the buyer may have changed his mind about getting another model, or that some specifications are not met. Whatever these reasons may be, the desktop is still in top shape. And since they are refurbished, the price is not similar to that of a brand new one. So you basically get the best price and quality ratio for this particular product.
  • And since most refurbished units are processed by the manufacturers themselves, it may also come with a warranty – although not for a while as the brand new ones. But still, that is a great thing, right? With the prices of electronic gadgets soaring up at present, it is a good idea to ask manufacturers first for their refurbished products.
  • A number of business applications have the same basic software criteria. This means that refurbished units can perform any other tasks delegated to more upgraded models.
  • As a matter of fact (in relation to the above mentioned point), there are newer products (meaning more upgraded models) which are available as refurbished units available in most stores. This certainly makes a lot of technically-savvy people out there really happy.
  • The software program and internal functions of the desktop is still up and running with refurbished units. This simply means you can still do a lot with this type of equipment – and at such a bargain!

It would be advisable to always buy refurbished items directly from the manufacturer. Not only do you get a warranty and a better price, you are also assured that it has been remanufactured and retested to perform well on its function and specifications.

Is your computer keyboard not working properly? If your answer is affirmative, then you are having a keyboard problem. But, you need not worry since a step-by step guide is for fixing your keyboard issues is being explained below.

First of all, you should ascertain the reason why your keyboard has failed to work. Confirm whether it is software related or hardware related. If it is hardware related problem, then you should clean the keyboard by using a duster or simply shake it off. After this, you need to check whether it is plugged correctly or not. If it is a PS/2 keyboard, then you need to ensure that it remains plugged in the purple PS/2 port (This is not the case where you have a USB keyboard however). While doing work on your computer if it stops to work all of sudden, then you should plug it out and then plug it back in. In case, it fails to work, then you should try to fasten the keyboard to another computer. If it does work there, then you have a bad port or your computer has developed a software- related problem. If you plug it to another computer and its fails to work, then the pins of your keyboards might be broken.

When we go deeper into why your keyboard is not working due to a software- related issue, then you will come to know that this solution is for your keyboard as well as for the optimal usage of your computer. Your keyboard might be having a driver-related problem. Remember that a driver is the communicating medium between the operating system and the hardware. Without having it, your operating system will fail to identify anything which your hardware likes to do.

Many hardware manufacturers update their products drivers monthly for fixing your present keyboard driver problem and all other driver-related problems, which you may have. It is recommended that you spare the time for looking for a website or software, which will search for the drivers which your computer needs for running at a good performance. Remember that updated drivers allow your computer to remain the best. It is a pertinent factor in avoidance of the errors in your computer.

While looking for the website or software, which will help you in finding the right and updated drivers for your computer, it is very important to take heed that there are such websites, which will provide you outdated drivers, which you do not want to have. So be vigilant!

Upgrading power supply to computer is very important since it supplies the sufficient amount of power, which is required for making other components work in a proper way. As a result, you will be able to work on computer with much convenience and ease.

PSU (power supply unit) is undoubtedly the most reliable component of computer, but unluckily people considered it just for granted. Computer users are generally more preoccupied with upgrading their hard disks and video cards, but what they fail to realize is that with no PSU, they would be unable to get extra storage capacity. That is the reason why it is very important to choose the suitable power supply unit so that you are able to harness the computer to its fullest.

Now the question arises, how to upgrade the power supply for your computer. Well, you need not worry for it. Steps are being explained below:

  • First of all you need to know how you will make use of computer for determining the amount of power that you need. For example, if your purpose is to make use of gaming, then you need to have a unit, which has a capacity of minimum 650 watts. If you are doing basic tasks, then a 350-400 watt unit will suffice.
  • Secondly, give priority to quality. You need to be highly vigilant with the quality of PSU, which you will purchase. You should not choose the one for getting over with-take time in order to compare and review various brands. Keep distance from an inexpensive unit since it will fail to do any good for you. Simply, it will destroy the parts of your computer as soon as it starts breaking down in the future. Therefore, if you want to get rid of damage to your computer then get a premium unit, which has many optimistic reviews of its users.
  • Buy a reputed brand. Bear in mind that the power supply to computers is a difficult component. Therefore, you should buy the best brand to make sure performance and quality of your power unit supply. Such reputable brands will be more high-priced in comparison to lesser-known ones, but think it as a good investment.

So, this was all about how you can upgrade power supply to your computer. Steps on upgrading power supply have been clearly explained above. Remember that power supply is an indispensable part of computer. Without it, computer will fail to work. Do not consider it as a trivial thing.

So you’re asking yourself this, “What are computer processors?” Okay let me explain as best as I can. The processor also known as the central processing unit interpreting carries out the basic instructions that operate a computer. Simply part is the brains of the computer and the faster this processor is the better it can communicate with the computer. It significantly impacts overall computer power and manages most of the computers operations. A basic computer only needs one processor to do a whole lot a tasks. The newer version of the processor, the faster you can perform applications without waiting; that’s basically it really.

Now when people tell you a computer has more processors, they are referring to mainframes and supercomputers that power users utilize on a daily basis. Hmm let’s see… What is a good example I can give you? Ah, remember how meteorologists use mainframes and supercomputers to accurately tell the conditions of the weather and forecasts? Yeah, something like that. Even better, what about how NASA uses these mainframes and supercomputers to communicate with astronauts effectively? Yeah, that.

Very important here, this is where I get right down to it. Processes contain a control unit and arithmetic logic unit or ALU. These works side-by-side to perform processing operations. Like I said before is much like the brain in this case when it comes to computers. Let me put it this way to you almost all devices connected to the computer has to communicate with the processor in order to perform functions effectively.

The ALU performs arithmetic, comparison, and logical operations. It is much like mathematics in the eyes of the processor, and like most cases it does not understand letters and numbers. What it understands is on and offs like the switch you see on your desktop or laptop. Most of it understands ones and zeros. Arithmetic operations like basic calculations such as addition, subtraction, multiplication, and division a lot faster than way back in the 1940s. Comparison operations needed for database entries; you know stuff like what is graded then, equal to, or less than the other item. More important usage of this is business when the employer has to determine overtime pay. Logical operations such as and, OR, and not; again important for business operations. Software that uses these operations in full what I have experienced is Microsoft Excel and Microsoft Access.

All processes have to go to a set of instructions. Okay let me explain this to you a bit to understand. Okay let’s say you want to enter a mathematic problem into the computer. All right, let’s say you want 42 x 56 and imput it into the computer. The first process is the fetch operation which is basically obtaining a program instruction or data item from memory. The next part for the control unit to do is to decode that data for it to be sent to the ALU. That part is the process of translating that instruction into signals the computer can execute. The ALU then executes this command and performs the necessary calculations needed on the day that was sent to it. Basically it was executing 42 x 56 = 2352 as the results. Now the last part is to storage of this data or storing it. It just means writing the result into memory, but don’t get confused as this is not storage medium. Besides, it was just giving you an answer of 2352. By combining all of these instructions, it is known as the machine cycle of the processor. Keep in mind that processes back in the old days perform only one instruction at a time.

You may not notice this but you should be grateful for a concept that most modern processors have; this is known as pipelining. This just means that more instructions can be processed instead of having you wait. This is why modern known processors are so powerful because there are more pipelines for you to do many instructions with. Think of it more like employees that do the same thing as their job description. The more hired hands, the more people can get done whereas only one person you have to wait until their job is done. In a logical computer sense, by the time the first instruction is in the last stage of the machine cycle, the other instructions sent to it could have finish before it. Makes more sense if you open up more than one application on your computer to put it bluntly.

Let’s talk about things like registers (yes they are also part of the processor but not the part of the memory). You may heard of things like cleaning up your registry data but you really don’t know what this is don’t you? Well, they temporarily hold data and instructions. Registers come in different varieties all with a specific function. When I talk about the machine cycle, registers store practically what happened during the process.

Very important here, the process relies on a small personal circuit which is known as the system clock. You may wonder why people talk about overclocking your processor. Well ladies and gentlemen this is the source material of it the first grasp and understand. Just like the heart in the human body has to beat in order to keep it alive. So does the functions of a system clock. It generates regular electronic process, or ticks, that set the pace of components of the system unit. The clock speed is part of the pace of the system clock which is measured by the number of ticks per second and it is measured in hertz. More processors today range in the gigahertz. The actual system clock is one of the major factors that influence the computer speed. The faster it is the more instructions it can give per second. Please note that this does not affect on other devices such as the hard drive and the printer. Remember the process is actually put on the motherboard and it is the brains of the computer.

Quite a bit of info about the processor but I hope this post clears up the information about what the actual processor is and why it is so important on the computer.
