Diagnosing Computer Hardware Faults

When your PC goes wrong and you have lost all hope the normal final stage is to reformat your computer and start afresh. This will most likely resolve any software issues, remove viruses or any other nasties and give you a clean start. But what happens if you have already reformatted and the problem still exists?

This means, most likely, you have a hardware fault. This is where problems can start.

Diagnosing a computer hardware fault can be a right pain as any of the computer components could the cause. Unless you are intending to replace the entire machine you need to carefully diagnose with what components the fault lies with.

Diagnosing Computer Hardware Faults

I would advise you look at the computer into these main areas to analyse.

Memory / RAM

Power Supply

Hard Disk

Motherboard

This isn't a complete definitive list, obviously depending on your issue ie if your issue is that you don't get sound then it could be a sound card issue, similarly if you don't get a display then graphics could be the culprit. If it is a random fault then either of the above could be the cause.

Memory - this is fortunately quite easy to diagnose. Search the Internet for a memory tester. Generally these can be put onto a CD (or Floppy if you are stuck in the past!!), boot up from the CD which then enters the memory test. This will constantly cycle through, testing the memory for errors. It is wise to leave this on for several hours or even better over night. It will advise you if the memory fails.

Power Supply - this can be a strange one. People generally assume that if the power supply does fail then you would get no life from you computer at all. This sometimes is not true. I have had computers that turn off at random times, computers that have the power light on, but do not start up etc and it has turned out to be the supply - I would advise this should be one of the first things to test as can be a problematic area. Testing it can be difficult without the right equipment. Really the only way is to get a volt tester and check the voltage and current coming out.

Hard Disk - this can be one of the worst problems to have as if your hard disk does fail, unless you have been sensible and done regular backups of your most valuable data, you stand to lose it all. Hard disks can go at any time and usually you will hear a harsh sounding clicking noise that is coming from your computer. If this is the case you need to probably replace the hard disk. Get someone who then knows what they are doing here to try and recover your old data for you.

If none of the above solves your problem then you could possibly be looking at the fault being with the motherboard or any other plug in cards or devices you have. Remove everything to leave only the very basics. Take out all sound cards etc and any other PCI devices that are not essential. If you have more than one stick of ram then leave in only one and see if the problem resolves.

Really, solving hardware issues comes down to a case of trial and error here so take the time to test everything out. Bear in mind that even if your keyboard or mouse is faulty, very strange things can happen to a computer, so if you can, try to remove and test every single item.

Free Bunk Bed Plans

Using bunk beds is a good way to maximize space, especially if your floor area is very limited. This type of furniture is actually very popular and commonly found in the rooms of children, residence halls of colleges and universities, ships and trains.

If you are interested in creating your own bunk bed, you need to get sturdy materials together. Wood, plywood, deck screws, carriage bolts, nuts, washers, wood plugs, finishing nails, lag bolts and lock washers are often used in building such beds. The number and size of the materials depend on the size of the furniture that you will be making.

Here are some reminders before you start building your bunk bed.

Free Bunk Bed Plans

1. Evaluate the room where you want your new bed to be. Plot the space that the bed will occupy and make allowances for the rest of the furniture in the room. Now get accurate measurements of the space where you plan to put your bed. Visit different hardware stores and acquire the needed materials before you start on your project. Make sure you shop around for the best possible deals.

2. In building your bunk bed, make sure that you will be able to get standard-sized mattresses for it. Before you start cutting through the wood you have purchased to build your bed frame, make sure that you have made allowances for your mattresses. It would be unwise to have a large frame for your bunk bed when your mattress is a lot smaller, or have too small a bed frame that causes the mattress to spill out at the sides. Make sure that you construct the lower of the two bed platforms at least twelve inches off the floor. As for the upper bed box, it could be any height.

Computer Hardware Comparisons

Hardware is the electronic, electrical, and magnetic components that carry out the functions of computer. Motherboard, processor, hard disk, random access memory (RAM), network cards, video card, sound card, and internal modem are examples of such components. It also includes peripheral devices such as mouse, keyboard, monitor, modem, printer, and scanner. Hardware components with specified capacity are essential for the effective functioning of running software applications. There are several companies, most of which are leading electronics brands in the world, involved in the production of various components. To help users to select the kind of product they need, computer hardware comparisons are provided in computer magazines and technological websites.

The most important computer hardware component is microprocessor. It is an IC designed and produced specifically for doing various computing functions. There has been an intense competition in the field of the microprocessor field. The two main players in this field are Intel and AMD. There were other companies like Cyrix and a number of Chinese manufacturing companies. The competition so far has been good for the customers for getting good quality products. The two companies are engaging in an exciting competition for outdoing each other. When AMD makes a processor with a special feature, Intel will soon come with a processor with some other feature that is more attractive than the AMDs feature and vice versa. The cycle continues and the quality and speed of the processor increase.

Another major component among computer hardware is motherboard. Basically, it is a custom designed electrical and electronic circuit. It is on this board that the other internal components are slotted in. It has specific slots for specific components such as processor, hard disk, RAM, network card, graphics and video card, sound card, and internal modem. Intel also manufactures its own motherboards. It is said that for Intel processors, Intel motherboards work best. Another major company in the field is Mercury.

Computer Hardware Comparisons

Another field where a number of computer hardware comparison reviews are available is in the field of computer memory. Broadly speaking, computer has two kinds of memory: magnetically controlled permanent memory and electrically controlled temporary memory. Hard disk is the permanent memory. The major brands of computer hard disk are LG and Seagate. RAM is the non-permanent memory, which is used for the functional memory while running the computer.

Computer hardware comparisons of various peripherals are also available on magazines. In the field of computer monitors, LG, Acer, and Phillips are the major companies. Most of these companies have mouse and keyboards too. Microsoft and Logitech are the other major manufacturers of mouse and keyboard. In the segment of printers, HP, Epson, and Canon are the major players. Samsung, LG, and Creative are the major companies that manufacture CD and DVD drives and writers.

Lowe's Catalog Sales Offer Convenience and More Selections

While shopping at a Lowe's direct location has its benefits, another shopping option exists that you might not be familiar with. Lowe's Catalog Sales often offer customers many selections that you will not find in-store and often offer discounted items. A copy of the their catalog should be easy to find, as they are located in every single store. However, if you are for some reason having a hard time finding one, ask a sales associate or go online to the Lowe's site in order to find information on how to acquire one. There are several reasons shopping with Lowe's Catalogs might be a good idea for you. First, it is convenient, as you can do all of your shopping from the comfort of your own home or office. Second, their catalog is able to offer you a wide range of products that local stores do not have enough floor space to display. Lastly, anything purchased from their catalog can be delivered directly to your door.

Convenience is Key

Life is busy. Most people have work and family obligations that leave them little time to schedule in long shopping outings. If this is the case for you, Lowes catalog sales might be a good alternative to in-store shopping. Their catalog gives you all the specs on each product you are interested in purchasing. You can browse through these products when you have free moments at work or at home or even while you are stuck in traffic! Once you have decided on which products you would like to purchase, the ordering process is very simple. Simply go online or call the number provided on your catalog. After placing your order you will be asked to provide some personal information, after which, you will be done! With no lines to wait in and no hassle.

Lowe's Catalog Sales Offer Convenience and More Selections

Variety is the Spice of Life

Every Lowes store has only so much floor space on which to display their products. Therefore, if you have shopped and have not been able to find exactly the product you are looking for, Lowes catalogs might be a good place to find what you need. Each catalog has many products in it that are not on display at their retail locations and often they have products listed that are ONLY available through their catalogs. So, before you give up on finding the perfect fit for your home or office, look in their catalog. They are likely to have exactly what you need.

Delivery Makes Life Easy

Once you have found the perfect product using Lowes catalog sales, simply notify the company of your choice for delivery. For a relatively small charge, you can have number of products delivered to your door. Instead of getting a truck over to Lowes and dealing with the hassle of loading it, why not let the company do it for you? Most delivery options offer very quick delivery, often having your newly purchased items delivered to your home within the week.

Ten Ways Companies Leak Their Secrets and How to Stop Them (Without Hardware or Software)

Companies willingly or unknowingly give away 10 times more confidential information than could ever be hacked from a network or stolen from a file cabinet. Employees, from golfing CEO's to helpful admins, cost their companies millions in lost business and fizzled strategies every day because trained business intelligence collectors and analysts take the bits gathered not only from employees, but suppliers, regulators, customers, the media, and even total strangers, and assemble them into accurate hypotheses about a company's future actions. Then they can decide how neutralize each possible initiative.

Fortunately, the most practical and cost effective solutions to curb leakage of confidential information is essentially free, simply by implementing an awareness raising campaign and some information protection policies. No new hardware, software or headcount. Being proactive about safeguarding your sensitive information and understanding how competitive intelligence specialists operate, can save your company a ton of money and grief. Here are 10 vulnerabilities and solutions to get you started.

Know what your secrets really are. This is absolutely Number One. Most companies don't know what information they can or should protect, or for how long. Even senior officers at most firms won't often agree on what their company's secrets are. As a result, employees at all levels make their own decisions "on the fly" about what information they can share with acquaintances, at the trade show or on the 'Net. This makes a company vulnerable to an intelligence attack by rivals who interview as many of their target's employees as possible to get the whole story.

Ten Ways Companies Leak Their Secrets and How to Stop Them (Without Hardware or Software)

Sensitive information is not limited to formulas and customer lists. The formula for Coca-Cola is one of the most closely guarded trade secrets, yet who would buy Fred's Cola? But travel itineraries, for example, are almost bragged about. The extraction an exploitation works something like this: While waiting behind The Lunch Company's sales person in the registration line at a trade show, The Shark Company's intelligence collector simply starts complaining about business travel and his hectic schedule after the show. This elicits a macho one-upsmanship of Lunch's post-show itinerary. That evening Shark's collector sends a Flash-Urgent email warning his field staff in those cities of Lunch's planned visit. There's plenty of time for the Shark team to give their customers fresh objections to the Lunch's product. Two weeks later, Lunch's sales person has no recollection of the conversation, but also can't figure out why all his customers got so difficult.

Solution: Management has to determine exactly what the company's secrets are, and to safeguard them by insuring every employee is either aware the information is confidential, or has no knowledge of it. Guidelines and training sessions sensitize employees to all the opportunities there are for leaking information.

Compartment information. This means implementing a "need to know" policy for your company's future plans and major projects. An engineering "team member" at Gillette was prosecuted a few years ago for delivering the complete plans for the Mach III razor to American Home Products prior to the razor's launch. American Home didn't bite on the offer and cooperated with Gillette on a sting operation. A nice piece of corporate responsibility, but why did an engineer have access to marketing plans in the first place?

Solution: Compartmenting information can be difficult to implement in today's open door and open cubicle workplace, and remote workers make the situation worse. Nevertheless, employees can be made to understand that need-to-know has nothing to do being trustworthy and everything to do with limiting the number of people possessing the company's complete plan. The fewer targets, the less likely one will be found and possibly exploited by a rival's intelligence workers.

Track requests for information. Competition drives companies to be generous with information without much regard as to who is asking for it. As a result sensitive information may be too easily released. Few companies catalog information requests beyond calling them sales leads and passing them along.

For example, once a high tech software company began tracking domain names of website visitors they learned the domains of the top seven most frequent visitors were all owned by one of their largest competitors. Yet they anonymously visited the web site up to 400 times in the 24 hours after every new press release looking for the slightest snippet of useful information.

Solution: Analyzing inquiries for information, including print, electronic and interpersonal, reveals patterns that signal which competitor watches your every move, and what subjects are of interest. Inquiry analysis also provides an early warning of new competitors sizing up your company. Having a central point for information requests and a hot line for the real strange ones sensitizes employees that the company is an information target. Done correctly, vigilance has no impact on the flow of information to genuine prospects.

See your Web site as the competition does. Is your Web content too revealing? A wireless company offered enough information through white papers on their site and a shopping cart for other documents sufficient for a competitor on the other side of the world to copy its latest technology. In another example, entering a wildcard with a spreadsheet extension, *.xls, in the Search window of a home page caused a number of sensitive spreadsheets with past performance and future marketing budgets to fall out.

Solution: Forming a "red team" of employees with customer and competitor experience to review new Website material is very worthwhile. Projecting how competitors might interpret the new content can be a real product saver at no additional cost and very little investment in time. And never distribute internal information through your Website no matter how protected you think it may be. It isn't.

Monitor blogs, chats and resume sites. No one can fault an employee for seeking greater opportunities by putting their resume on an employment site, or enhancing their professional reputation with discussions or publications on the internet. But a great deal can be learned from an over-detailed resume. Just the fact that lots of resumes from your company pop up on an employment sites can indicate employee insecurities within your company, attracting the interest of you rival's intelligence officer. Compulsive chattering by employees on blogs may or may not leak confidential information, but more importantly such activity flags your employee as a willing talker who can be steered by an intelligence interviewer to confidential subjects.

Solution: Again, a high awareness projected throughout the company that every employee is an information target, and that the company's success and their personal stock holdings can be seriously impacted with too much exposure.

Make employees feel genuinely valued. Hundreds of interviews with people convicted of leaking or selling government or commercial secrets reveal one motivation they all have in common. It was not money, revenge, or ideology that drove them to leak information, but feeling their work and loyalty was unappreciated.

Solution: Simple expressions of recognition make a powerful tool for reinforcing loyalty, and emphasizing the importance of adhering to information protection rules. After all, no one wants a company that values them to be hurt by competitors.

Follow the money, and then hide it. There are lots of leaks in your supply chain. A competitor doesn't have to know how many widgets you make if the company supplying items like the cardboard boxes or training CD's brags to a "prospect" about how much he sells to you.

Solution: Every link in your supply chain must agree that transactions with you are confidential and your company cannot be given as a reference. Other "cloaking" techniques can include patenting five things that don't work for every one that does; creating shell companies to buy land parcels or other large, divisible purchases; or using an intermediary to file public documents such as environmental forms on behalf of the true company.

Everyone signs the non-disclosure. Too often managers sign non-disclosure agreements with customers, contractors or vendors but few people below management level are aware of what the agreement covers or that it even exists. An employee who is unaware of an NDA or what it protects can reveal a great deal to a trained interviewer and it will be very difficult to prove either party guilty of wrongdoing. This is doubly problematic considering today's heavy use of outsourcing. Today's contractor could work for tomorrow's competitor. An engineering firm once hired temporary engineers to complete a new product on time. The temp firm got their engineers from another firm owned by the archrival of the original client. The new product line was dead on the drawing board.

Solution: Joint ventures should be started with bulletproof non-disclosures, due diligence and security briefings for all the employees involved. A control function should recover shared documents, disks, software, presentations, samples, or prototypes at the conclusion of the project. Again, not much investment in cash, just some changes in culture.

Over reliance on technology. Wireless networks at coffee shops are not the place to do business regardless of what type of encryption or password protection your files have. Wireless hot spots are designed to be as open and simple as possible, and there are plenty of tools available to sniff out your login. Actually wireless anything is risky. Perhaps you have booked a major sales meeting at an offsite location with all the multimedia bells and whistles. Unbeknownst to you, a competitor is sitting in her room at the hotel, sipping coffee in her bunny slippers, listening to your entire conference because the presenters at the "closed" meeting are using wireless microphones. Signal can carry 100 to 300 yards. Illegal? Absolutely. Done every day? Absolutely.

Solution: Again, awareness. The decision to use anything wireless needs to be balanced for convenience, leakage potential, and the value of information being sent over the connection. Also, keep camera phones and keychain hard drives out of sensitive areas. And unless you encrypt them, "smart" access cards and RFID chips are a really dumb idea. They can be downloaded with equipment available on Ebay, and a simple "brush by" in a crowd. You want the world at your doorstep but not in your laboratory.

Innocence. Everyone wants to believe the world is a nice place. And like most nice places the world has bad neighborhoods. Territory and ideology were long ago replaced by market share as the top interest of nation-states. A country that can't compete for markets has little influence on the world stage, and a country that can't support a healthy population with food, and infrastructure is very vulnerable to internal strife. Since the end of the Cold War thousands of government trained intelligence officers switched their focus from political success to the economic success of their countries. If your products involve high tech, construction, health care, natural resources, biotech, utilities of all kinds or food production, to name a few, they are "national interests." You are on their radar.

Solution: Getting tired of hearing this? Awareness. There is a whole set of precautions that should be taken by business people traveling abroad where local companies often work hand in glove with their state intelligence services for the national good. From pulling hard drives out of your laptop left in a hotel, to being just a little skeptical of "new best friends," at the fancy embassy cocktail party, the biggest information leaks start and stop with people, not hardware or software.
