mother board repair and troubleshooting

It is difficult to get a piece of technology to work as good as it used to, once it's broken. Which is why most 'repair' procedures stay with hardware enthusiasts, because the best option for most other consumers is to replace it. With that in mind, we look at the resources that we have and try to get the best out of it.

The motherboard is located inside the cabinet and consists of a microprocessor, chipset and BIOS (Basic Input/Output System). The microprocessor decides the type of Central Processing Unit (CPU). The chipset constitutes two bridges: the north bridge and south bridge. These bridges control the flow of data in the computer. The basic functioning of the computer is controlled by the BIOS, which is a real-time clock and a major component of the motherboard. The slots and ports on it connect the computer peripherals like the sound card or graphics card. These slots provide a connection between the hard disk and the computer peripherals.

Troubleshooting a Bad Motherboard

Hardware diagnostics can be a pure pain in the ass. There is literally too much going on in there to efficiently dissect the faulty stuff and repair it. This is why most repair work is usually done by professionals or hobbyists. It takes a long time to get a full grip on handling hardware issues with precision. That said, there are a few common problems with pretty easy solutions as well. Let's have a look at the MoBo (motherboard) itself for any repair options.

Replacing Capacitors
The constant problem of popping capacitors is well-known by professionals and enthusiasts alike. Capacitors are the first thing to blow in a well-built electronic unit. The problem persists wherever a capacitor is used (commonly called the 'Capacitor Plague'). The only option to this is to replace the capacitor with a new one. Spotting a bad capacitor is easy: it's the one with the bulging top and leaking electrolytic goo. Most capacitors expel the electrolytic fluid inside them. It either dries up on the outer part of the top of the capacitor or leaks on to the circuit board. Worst-case scenario, the capacitor explodes due to too much electrical stress. If you see no damage on them, you can still check them using a capacity gauge or a multimeter.

To replace the capacitors, you will need:

a program-controlled soldering station with both soldering and de-soldering irons,
genuine capacitors of the same capacity as the old ones and
experience in soldering and knowledge of the risk involved.

Because one false move and you'll damage the internal circuitry of the board and lose the board completely. You have to de-solder the pins from under the board, take the dead capacitor out, put the new one in and solder the pins back; all in one shot. You need to be extremely cautious about the polarity of the capacitor. If you put it in the wrong way, the capacitor pops almost as soon as you power it up.

Motherboard Component Diagnosis

POST Check With Beep Codes
To diagnose a problem, you need to know where to look. The first stop would be the BIOS POST (Power-On Self-Test). If your computer (not your speakers, your cabinet) makes beeping sounds when you start it up, it means there is a problem with certain part/s on the MoBo. This is good (relatively speaking) because the beeps will directly tell you what's wrong. Pay close attention to the kind of beeping sound (the duration - short or long and the number of beeps). Search online for the 'computer beep code' and you should have found out which component is faulty. This will only work if the parts are on the verge of going down. If something does go down, your computer probably wouldn't start and you'll have to figure out the problem manually.

HOW TO CONNECT WIFI IN MOBILE PHONES-HOW TO CONNECT WIFI IN ANDROID PHONES

How to connect wifi in android phones:
 
    If your mobile phone is a top of the range model it will have WiFi connectability in addition to 3G (or similar) cellular network broadband.

The WiFi is intended to connect to strictly local area networks .such as WiFi hotspots in cafes or your home wireless router's internet connection. To use hotspots you may have to pay or perhaps get the staff to guide you on settings.

You may be able to detect other people's private WiFi signals but, these days, most apply wireless security and unless you have the password you won't be able to connect.

Simple steps :
  1. switch on wifi connection on your mobile

how get traffic you blog and how create seo (search engine optimization)

Over the years, we've grown the Moz blog to nearly a million visits each month and helped lots of other blogs  too. I launched a personal blog late last year and was amazed to see how quickly it gained thousands of visits to each post. There's an art to increasing a blog's traffic, and given that we seem to have stumbled on some of that knowledge, I felt it compulsory to give back by sharing what we've observed.
Advertisers on Madison Avenue have spent billions researching and determining where consumers with various characteristics gather and what they spend their time doing so they can better target their messages. They do it because reaching a group of 65+ year old women with commercials for extreme sports equipment is known to be a waste of money

SEO Techniques For All Newbies they should be doing

If you’re a startup entrepreneur, chances are good that search engine optimization (SEO) is the last thing on your mind. After all, why should you worry about things like keyword phrases and backlinks when there are a hundred other items on your “to do” list, all clamoring for your attention?
Unfortunately, this mindset is extremely shortsighted. It doesn’t matter how innovative your products or services are. If people can’t find you online, you’re going to have a seriously tough time sustaining the momentum you need to propel a growing business to success.
So instead of dismissing the tremendous potential involved with SEO, consider implementing any or all of the following techniques into your startup’s marketing plan:

 Identify Target Keywords

In my opinion, a startup’s marketing goal should be to identify at least a handful of potential SEO keywords to target within the natural search results and then optimize the site accordingly. This list should include keyword phrases that your potential customers are actually entering into the engines (as determined by search volume figures found in keyword research tools) and that aren’t too competitive to rank for your site (based on the presence of established websites in Google’s Top 10 results).
Once identified, these keywords should be integrated into your site in key areas, including your page titles, your heading tags, and your body content. Don’t force it through excessive inclusions, but do take advantage of the SEO value these positions hold to inform the search engines about the subject of your web content.

Implement Branding Efforts

However, while it’s important to identify and target SEO keywords for use in your startup marketing plan, it’s also vital that you begin the branding process as early as possible in your company’s tenure. There’s no arguing with the fact that Google loves brands. Considering that the search engine must rely on quantifiable metrics (rather than subjective assessments) in order to evaluate website quality for display in the natural search results, branded elements remain one reliable bellwether that can be used to indicate viewer valuation.
To get started capturing these benefits for your startup’s website, decide on a set logo, color scheme, tagline, and promotional phrasing as early as possible, and use these elements consistently across your web presence.  Consider working with a graphic designer or marketing consultant if you don’t feel capable of coming up with a cohesive brand on your own.

Focus on Content Creation

Running a company blog on which you post product updates, industry news reactions, or other personal interest pieces is a vital part of SEO for two reasons.
First, publishing content to your site regularly increases the number of different keywords present on your site. By improving keyword exposure, you may find yourself earning free SEO traffic via natural search phrases you never even targeted on your site
Second, filling your site with valuable content is a great way to build up the relationships you share with your prospects and customers. Because bounce rate and time on site are both believed to be playing roles in search ranking algorithms, the quality of these relationships could actually improve how well you rank in the SERPs.

Commit to Social Networking

Truth be told, for many startup entrepreneurs, participating on popular social networking sites can seem like yet another chore to be added to the “to do” list. Don’t let yourself fall into this trap!
Both Google and Bing have acknowledged that social signals, including link shares and brand mentions on some social network status updates, are currently playing a role in natural SERPs rankings, which means that maintaining a presence on these sites is vitally important for your startup’s SEO. If at all possible, make it a priority to invest at least 10-20 minutes each day posting to social networking sites and interacting with the people who follow your company’s profiles on these sites.

Connect with Social Networking Power Users

While you’re spending time on popular social media sites, it’s also a good idea to take the time to connect with the power users on these platforms. Not only is the relative authority of these social networking participants taken into account when weighting the social signals Google and the other search engines detect for your brand, a single link share from one of these “influencers” could result in a significant influx of traffic and customers to your website.
To do this effectively, identify the people you’d like to connect with based on their numbers of followers and their general authority within your industry, and then let your relationships with them build up naturally. Sharing their content or offering to help them in some way will go a long way towards ensuring the success of your eventual share request.

Install Google Analytics

Another foundation to web success that all startups should consider is the ability to measure and test different metrics. For example, if you’ve recently added a new sign-up form to your startup’s website, you’ll want to be sure it’s as effective as possible, and you can’t know that if you aren’t measuring the results you achieve through A/B or multivariate split testing.
To gather the data needed to do this effectively, you’ll want to install a program like Google Analytics. It’s free and easy to use, and it provides an incredible wealth of information that can be used to improve your website’s conversion rates.

Set up Google Analytics Goals

Speaking of conversion rates, once you’ve got Google Analytics installed, you’ll want to take the time to establish website goals and set up the necessary event tracking features to determine how well your website is performing. Because Google Analytics goals allow you to identify whether or not website visitors are engaging with your site the way you envisioned, they’re a vital part of making your site as effective as possible.
