How to build your own computer A free tutorial for a low cost solution for a new computer So you want another computer, or maybe you've just thought about getting a new one? The kids are fighting over who's turn it is to use the PC, maybe your current computer is getting a tad bit too slow, or perhaps you'd just like to start your own home network, or expand it for that matter. Well here you'll learn how you can build your own computer in easy to follow step-by-step instructions. I'd personally suggest that you review all of the information here thoroughly. Let it sink into you, and then, once you feel ready, take out your checkbook, get yourself a screwdriver and have some fun! 1. Deciding what type of system you really want or need Before you go ahead and start building your computer, you should have a good idea what you will use this new PC for. Will it be: • To use for work? In this case you'll probably won't need such fantastic hardware, unless your work requires you to use some extensive software, such has 3D graphics, video and graphics, programming, CAD/CAM, etc. • To play video games with? If you want to build a new PC geared for video games, then you'll probably want to get some of the latest new hardware, so you can really enjoy all the new 3d technology now featured in today's video games. • Just to surf the web with? If you only want a machine that you can use to surf the web, use e-mail and chat, then you can rest assured that you won't really need all that much expensive hardware. • Just an overall system? Most cases often that not, this is the system people want. Just a computer that can perform a whole variety of tasks, without being to slow, and without being too expensive. • Do you want power computer? One thing is for sure; these types of machines are great fun, yet they tend to be quite expensive. You might also want to go ahead and grab a flyer of your local CompUSA, BestBuy, or Fry's Electronics (probably the best retail store for computer parts, but restricted mainly in the south west of the country). Take a look at the deals. You may want to wait until you spot a really good deal on parts before starting to build your system, or you can also get the parts as they come out on special. Of course, there is nothing wrong about shopping online for your parts either. You can often find some good deals, when you don't have to pay an arm and a leg for shipping. In the end, what's the most important is that you shop around. Don't let the fancy ads make you dish out your credit card or checkbook right away. Find out if other stores have something similar, or even the same product for cheaper. Another thing, if you want to save money, don't always go for the best brand name, yet don't go for the cheapest item on the shelf either. Low priced items might look nice in the box, but once there in your computer, you can really start regretting it. 2. What exactly you need to buy Out of all the steps outlined in this How to build your own computer guide, this is the one I dislike the most. Why? Well, just about every time I go out and get the parts I need to build a new PC, I tend to come Overcome your own laziness Overcome your own laziness Bởi: Joe Tye “Ultimately there is only the one impediment, and that is laziness If we overcome laziness, all the other impediments will be overcome If we not overcome laziness, none of the others will be hurdled.” M Scott Peck, MD: The Road Less Traveled Ouch! I don’t know about you, but for me that hurts to read – because it hits too close to home It’s not just physical laziness – more important is mental laziness We’ve seen that Dr Mihaly Csikszentmihalyi (author of Flow and The Evolving Self) says that the most depressing thoughts have to with the self Unfortunately, when we are not consciously structuring our thinking it tends to automatically and spontaneously gravitate toward the self And often when our world has turned upside down (as in the loss of a job or the failure of a business) we don’t have nearly the motivation to think about anything other than ourselves and the plights we have found ourselves to be in So we tend to wallow around in worry and self-pity and other forms of negative emotions and negative thinking It’s just too hard to focus our attention and our conscious awareness on something more positive and constructive In a word, we need to overcome our laziness Even if, in the case of the recently unemployed, you don’t have a job to go to where your thinking must be structured in a more positive direction for at least part of the day, there are things you can You can read an intellectually challenging book; you can work on building a personal website (or improving the one you have); you can volunteer for a worthwhile cause; you can spend more time at the gym and less time in front of the television set 1/1 Three Myths About Starting Your Own BusinessMistakes that hurt countless would-be entrepreneurs.Many people dream of shedding the corporate life and starting their own companies. They imagine creating the next Google or Apple. From Steve Jobs to Bill Gates to Pierre Omidyar, many of the world's richest people on the Forbes Billionaires List started as entrepreneurs, so it's little wonder so many believe that's the path to wealth and happiness. But getting a company going is hard and takes sacrifices, especially in this down market. More than 50% of companies fail in their first five years. Their founders spend much of that time skipping vacations and luxuries and sometimes even meals.I've started three businesses, and I've invested in others as an angel investor and venture capitalist. I've often struggled and failed. My second start-up made $7,000 over three years while I lived in a $200-a-month apartment. With another one I gained 25 pounds during the first year, thanks to too many hurried dashes to McDonald's. But I'm glad I chose the entrepreneurial path. I like the challenge of creating something from scratch.I've learned a lot from my experiences. Before you venture out on your own, I offer you three myths about starting a business that I wish I had known before I began.The first myth is that you should spend a lot of time preparing detailed business plans. Many business school professors and consultants recommend writing them with lots of scenario planning and financial projections. Far too many entrepreneurs lock themselves up for six months to labor away creating the perfect plan. The problem is that markets change so quickly that you don't really know how consumers will view your product. Those six months would be better spent better developing a product and trying to sell it. What has always worked for me is to write five to ten bullet points listing what I hope to accomplish and several back-of-the-envelope financial projections. Be realistic in your revenue projections. Too many entrepreneurs predict that their companies selling plastic flowers or whatever will hit Google-like profit levels within five years. But how many companies ever become the next Google ( GOOG - news - people )? Be realistic in your projections.Instead of writing a detailed plan with unrealistic projections, focus on figuring out those five or ten points and then get moving actually building a company. Every three months, look at those bullet points and see if you need to add to or change them. A business plan should serve as a guide, not a bible. Naturally businesses need to evolve to take into account changing market conditions. The second myth is that as an entrepreneur you have to develop the coolest, most innovative product. Instead you should ask yourself, will anyone actually buy my product? Entrepreneurs are often dreamers and inventors. Many get so caught up in the coolness of their products that they forget they need see if anyone will actually pay money for them. Take for example the Segway. It generated lots of buzz when it first hit the market. Who can forget President Bush falling off one in 2003? The Segway is a cool concept, but the market for it just isn't big enough to sustain real growth. Outside of large warehouses and airports, nobody needs it, yet the costs of producing it are huge.What you do need to do is get your product to market as soon as possible, to start generating revenue and gain customer feedback. All companies, large or small, need to be more customer-oriented than engineer-oriented. You have to take into account customer wants and develop products based on that feedback. Sales cycles for start-ups are far longer than most entrepreneurs expect. Estimate how long it will take to get to International Business StudyBUILDING UP YOUR OWN DREAMSAfter a long time effectively closing the door to foreign investors, VietNam has opened them again in recent years. The government has pursued an economic liberalization policy and introduced market - based reforms. Price controls in many areas have been scrapped, restriction on foreign investment have been loosened and so on. Let’s have a look at the factors of production that effect the decision making of “ Direct foreign investment may take place through either the acquisition of existing facilities or the new one (from the perspective of the host country like Viet Nam)”• Land: The S- shaped country, which has 330.930 square kilometers area of land and more than 3000 km length of the seashore, becomes more and more attractive. With a strategic location in the heart of South east Asia, Viet Nam’s long run prospects are too bright for many foreign investors to ignore. Investors can find a suitable place in hundred of the industrial zones with a reasonable cost. Thinking about building a large new factories or firms, expanding new offices, setting up new huge ware houses… Viet Nam ‘s land is available because of the existing out mode facilities as well as the lacking of new infrastructure investment• Labors: Young active Viet Nam’s labor force which are workaholic, easily trained and adapted quickly to new methods, technology. According to the Central Institute for Economic Management (CIEM): in 2001, the foreign investment sector alone provided jobs to 354.000 people, showing an increase of 20.000 against the year 2000. In general, Viet Namese workers have a relatively high education – attainment compared to that of other countries in the region; as much as almost 80% economically active people in the country finished their primary education or higher levels.• Capital One of the encouraging signs for FDI in Viet Nam is the large capital increase for business, and production expansion on a large scale. The value of the Viet Nam dong is still lower than the value of money from some home countries. The state bank of Viet Nam continues to use monetary instruments and adjust the credits and exchange rate regimes to make them more flexible and responsive to market signals with an aim Kieu Tram, Ngoc Thuy, Khanh Doan, Phuoc Vinh – ( KD0105) International Business Studyto attaining monetary stability and at the same time, contributing to the acceleration of economic growth.• Technology Forming an agricultural - SITEPOINT BOOKS Advocate best practice techniques Lead you through practical examples Provide working code for your web site Make learning easy and fun Detailed installation instructions Easy-to-understand diagrams Practical code examples WHAT’S INSIDE?
