What To Do If Your Computer Is Over Heating

When the computer heats up it is dangerous because it can overheat and you need to buy a new one, which are not always cheap. There are some ways to ensure this does not happen, and lengthen the life of the CPU (Central Processing Unit) and other devices inside the computer.

A major reason for computers overheating is the lack of airflow , using a laptop and have it in your leg or arm of the sofa, it's likely that fans of laptops are ultimately not receiving any fresh air into the laptop, since they are covering the ventilation openings. To ensure that this is not the case, place the laptop on a flat surface or on a laptop that has a grid like surface that allows air into the fan to cool the laptop down.

If you have a computer and it shows that the temperature of the CPU or motherboard is increasing, this maybe due to the room temperature becomeing warmer and that hot air is being sucked by the fan and not able to cool the laptop efficiently. Adding more fans would increase the airflow.

When checking the temperature, if you notice that the CPU is much higher than 40-60 ° C between the heat sink this may become a problem, this might be the wrong positioning of the heat sink or heat sink can loosen over time and lose contact with the CPU. In these cases, the best solution is to remove the heatsink and clean the CPU and put some new thermal compound on the CPU heatsink and turn around 180 degrees and put it back on make sure the CPU thermal compound is spread evenly over the top of the CPU .

When the back of the sink in place , safely restart the computer and check the CPU temperature to ensure this is correct, if not, then check if the fan on the heatsink is working properly, and if it is rotating at the correct speed. The new heat sink should only be necessary for the purchase, if there is damage to the original, can be installed in the same way as before.

If the problem persists, check if the thermometer is faulty, but in most cases, it is not, check if the cables which could impede the flow of air to the heat sink or a fan being obstructed .

In order to make sure the computer you are installing takes into account air flow, so when installing hard drives, DVD drives, make sure if possible air can flow between them and prevent overheating. If the units are very hot this increases the temperature and makes it harder to cool the computer.

Looking at the computer flow is almost as important as building a computer, if you do not allow easy flow of air inside the computer from overheating, and the capability to strike off the top. You may need to install more fans to provide air cold enough to reach your computer, but do not forget to install some of extraction fans that suck all the hot air out of the box.

Normally, with most cases, there will be a place in your computer case with a fan to be placed on the back which is usually the best place to install an exhaust fan and install a fan program introduction to the front of the computer case to blow cool air will be in this army of fresh air in the bottom of the cabinet, then the force of hot air to the rear of the case in a continuous cycle that keeps computer running at the ideal temperature.

Building Computer Basics: Graphics Cards

The energy consumption of individual components and how to choose a power supply that is more suitable to build a new computer is vital to the graphic card, and energy consumption varies greatly depending on what graphics card you pick. So in this post, we dig deeper into what graphics card is suitable for you.

First, if you look at the specifications of the card, try to focus on only four of them: the quantity of streams, the clock speed, memory and power consumption. Something that is really great about how ATI and NVIDIA is that they share the same label of the same system. The first digit of the model (for example, 9800 GT) shows that the generation that the card is. Today, AMD is the generation of 26, so the HD 6000 and NVIDIA series is version 15, they are labeling their card GTX 500. Also, avoid buying video cards that have four digits, if they do not start with Radeon HD. This means they are the previous generations and are an much old generation of cards.

The rate of the second digit the level of performance they are seeing the card (8 in the 9800 GT). Furthermore, the better the card is for this generation. So if you are looking for an 8 or 9, the card is pretty well the best that can be found in this generation. A 6 means that it is a card of the building performance for players, four is dominant, and all that is lower for versions of the economy. This number is also a shortcut to the number of stream processors of the card over other cards in their series, but is likely to be better and simpler to just stick to a single number.

The third number indicates whether the card is already overclocked or not (for example, the Radeon HD 5770). The number is usually zero, if the card has not been modified by overclocking.

The fourth number shows that the fourth generation card (similar to the first number). If there is a four-digit number on a NVIDIA graphics card, it means that you look on a card created in the first ten generations. If there are only three, it is newer than the (currently in the last 5 generations). If you look at an ATI (AMD) cards, ignore the fourth digit. This is pretty much hogwash. But with Radeon, Radeon # # # # cards are the first generation of Radeon X # # # # which is 11-19 and the Radeon HD # # # # is something newer than that.

Consider also the memory card. However, since the PCI-E 2.0 is now available, the memory is not as big as issue as it once was, but it does not mean that it is not important.I would suggest to get more than 512MB of memory for your graphic card.

Two more things ... trying to find the power consumption, as we've mentioned in previous messages. Knowing this will help you find what you need PSU, and will save you trouble down the road. Second, read the reviews on the card you are looking our for. These assessments are more (more like definitely)important than the actual specifications. Look around and see who else has the card and see what they think.

Oh, I forgot to mention. It may seem obvious to some people, but always try to get a card with a fan on it if you like the way the economy (most high-end cards come with one already). Those without a fan is just cheap and not worth getting.

Here are some graphics cards very worthy of note, you get the most bang for your buck out:

Radeon HD 5570 - $ 65 Radeon HD 5770/6770 - $ 130 Radeon HD 6870 - $ 195 GeForce GTX 570 - $ 330 GeForce GTX 580 - $ 450

All About Cloud Computing

Oh no. Just when you thought you got had gotten loads of confusing concepts in the computing world, here comes another one, which is perhaps the most obscure bits of each byte, or a buzzword in the world to come yet. It's called "cloud computing", and if your company has not yet adopted, it is very likely that not only will you be behind the curve to know what is available, but in reality, you may not be able to make use of some of the key advantages.

Cloud computing is the rage of today's business. Think of it as a computer nerd concept of the day. Unfortunately, as the public relations department, with the cloud,we all have a different definition of what it is about and the benefits it would give those who use it. Fortunately, in a very narrow sense, cloud computing is very much like what was once known as utility computing, or what others call the conventional outsourcing.

Cloud computing is known to users as a group of service providers, large and small, who provide services - storage capabilities to filter spam - for users without building additional infrastructure in its system. Instead, the IT department of a company is the focal point for service providers in a cloud individually, while with the integrator, who coordinate applications across the enterprise.

Cloud computing includes several key elements that make it particularly useful in IT systems across the company.

First, SaaS (Software as a Service), which provides applications via a browser to a virtually unlimited number of users in a user base. As with any application in the cloud, SaaS is not contained on a single computer, but is accessible across the enterprise to all users in an organization. SaaS provides users with access to the software without an upfront investment in servers or software licenses. In addition,only a single application is needed maintain the entire system.

The concept of utility computing,although it is not a new idea for computer users,allows the storage capacity that users are able to request and free up the enterprise system.

Web services are also available in cloud computing to deliver large-scale applications, to enterprise systems. Instead, applications on the Internet are able to run smoothly.

External developments have an important role in cloud computing environments to provide as externally from a corporate information system, in contrast to the standard development platforms. Instead of starting the development of a service outside the corporate information system.

Whatever the application, the flexibility and capabilities offered by cloud computing will be of huge benefit in the future.

10 Reasons to Upgrade Your Computer/Laptop

Computers these days can be compared with new cars - depreciate as soon as you walk through the door with them. Even if you decide to spring for the Tablet PC be rest assured that within six months it will be yesterday's news.

So how do you decide to keep what you have and try to improve it, or simply the difference and get a new computer or a laptop? A good rule of thumb is, if the cost of improving your computer exceeds the cost of a new, buy a new one. But here are some reasons why you should upgrade or replace the computer.

First Your needs are changing - the computer that you had as a student can not work when you enter a new career. Your laptop is a reflection of you and you may need to get a slimmer model, just to show that you are not late in the office.

2nd Career Change - If you leave your job to an editorial position in the graphic arts, you will probably need a computer with a good video card.

3. The new software - keep up with the latest software, you need speed, advanced graphics. Newer software does not work on older operating systems or can work less efficiently.

Fourth system crash, virus - Sometimes the most effective way to get rid of frequent crashes and viruses is to get a new computer.

5. Broken component damage - Repair broken screens, hard drives, CD-DVD Writer or water damage, which could cost more than replacing the entire system.

6th Too Slow - A slow system may require more memory. Adding memory is a popular upgrade that could cost less than $100.

7. Need for greater productivity - If the old system is slowing the work it is time to upgrade your computer. New software for word processing or image processing can be expensive. If the new system has pre-loaded software, it may be the best solution.

8. Reduced costs - computers are faster and cheaper than five years ago. If your system has more than five years, probably it will not be wise to pay for upgrading individual components, such as memory, hard disk and monitor.

9. Extraordinary maintenance - repair costs exceed the cost of a new computer, it's time to buy a new one.

10th "IT" Factor - If your job is very concerned about their image, it may not pay to be the one with the dull sound old when the new models have all the fancy new technology and look. It can improve your image , if you have new computer equipment.

All You Need to Know About Internal Hard Drives

The data storage technology is evolving very rapidly. If you were to analyze the growth of storage capacity and data transfer speed in recent years, you would have realized that in reality it has quadrupled. On the other hand , prices are staying the same. Therefore, upgrading the internal hard drive has never been so easy and convenient. In addition, using a suitable enclosure, you can change the internal hard drive , without having to pay extra costs. Hard drive enclosures are pretty cheap, and offer many advantages, because you can add as many, to protect the hard drive and to simplify the communication process as a whole.

When you buy a new internal hard drive, there are three elements to keep in mind, so the best decision. First, check whether your motherboard has an IDE or SATA drive as the need to purchase the right order to be compatible with your system. Next, check your disk space ,Although the price of HDD storage capacity will increase proportionally, running the space that fits your budget would be great. Finally, control the speed of data transfer, because it is a big enough impact on the speed of your computer can use, and therefore the overall system performance.

Internal hard drives can be purchased from both your online store or a local brick and mortar store. Buy from an internal drive online store offers several advantages over going to the shop and buying it yourself. Read reviews from customers about the product without ever leaving home. On the other hand, the traditional trade may employ a professional sales representative to make the best choice of the system. Thus, although both options will be their own interests, this is a matter of personal preference.
