When installing your Bluetooth enabled-device in Windows XP Service Pack 2, sometimes you will find this device can not be correctly recognized in Device Manager; if you try to use it, you will see some error massages like "Device not found" on the screen.

Commonly there are two cases that would cause this error: one is that the Bluetooth device has already been installed in your computer before you install Windows XP Service Pack 2, and you haven't installed the third party Bluetooth driver; two, Windows has automatically installed its built-in driver rather than install the third party driver.

Finding out and install the right third party Bluetooth driver may be a very complicated and time-wasting job, for there are hundreds of thousands of drivers for you to choose on the Internet, furthermore the Bluetooth driver used on one type of computer may not work on another because of differences in hardware specifications and operating systems. So you need a good driver tool to simplify your driver search and updates. Among numerous driver programs, Driver Checker is your right choice; with several clicks, Driver Checker will automatically search the Internet and manufacturer's websites for updated drivers that are specific to your Bluetooth device, operating system and compatible with your PC's hardware components so as to make the most out of the dongle.

And to resolve your Bluetooth device problem you can follow the methods below:

Method 1

Rename the bth.inf file: before setting up the third party driver, rename %WINDIR%\inf\bth.inf file as bth.bak, so as to prevent Windows Plug-and-Play using this INF file to set up Windows built-in driver.

Tips to rename this file:

Step 1 Click Start, choose Run, input %windir%\inf in the box and then click OK.

Step 2 Right click bth.inf and choose Rename, after that rename it as bth.bak.

Step 3 Download Driver Checker to install the best driver for your Bluetooth adapter.

Method 2

Replace Windows driver by specifying the third party driver for your Bluetooth device in Device Manager.

Step 1 Set up the third party Bluetooth driver and remember its location in your computer.

Step 2 Click Start, choose Run, input devmgmt.msc and click OK to open the Device Manager.

Step 3 Expand Bluetooth Devices and find out this device.

Step 4 Right click it and then select Update Driver

Step 5 In the update wizard, select Install from a list or specific location (Advanced) and click Next.

Step 6 Choose Search for the best driver in these locations and Include this location in the search.

Step 7 Click Browse to find out the address of your third party driver and then click Next to finish this installation.

Method 3

Use Driver Checker's automatic uninstall and install features to help you unload the inappropriate driver and install the compatible and latest driver quickly just with a few clicks.

With the conversion of Internet from a basic source of information to a major variable in businesses across the world, software scripts have taken a major role. In fact, the application of software scripts has multiplied at such a rate that companies that are not even linked to the IT sector have started keeping an in-house or consultant software script programmer. Companies require these scripts for various types of software like messengers, backend maintenance, website supporting software, or even internal network maintenance software. However, having an in-house or consultant software script programmer becomes very difficult for small to medium companies as it results in a lot of expenditure. Hence, many companies that cannot afford to keep an in-house or consultant software script programmer have started resorting to script resource websites.

As per recent trends, various small scale companies to medium scale companies have started using the services of these types of websites. The primary reason for such an en masse switch toward the utilization of these websites is that it allows these companies to save a lot of money. This financial efficiency allows the company to put in more money into its other operations and hence improve its total performance. As any statistician will agree, the number of small scale to medium scale companies is much higher than companies who can afford to have an in-house or consultant software script programmer. This ends up inducing a kind of proliferation for script resource websites in the cyberspace.

These websites provides scripts for dating software, audio and video messengers, shopping carts, and media publishing software among many others. As is apparent, most of these software would be extremely beneficial for Internet, Intranet, or communication based companies. Therefore, the kind of clientele that these websites enjoy include online shopping websites, blogging websites, networking websites, dating websites, and many other associated websites. In addition, these websites also take on special projects entailing script designing for highly specific software that a client may want. Furthermore, there are even certain websites that offer basic scripts for simple software for free. There are many online entrepreneurs in the market these days with new and innovative ideas but without appropriate capital to make their concepts work properly. Script resource websites are the ideal solution providers for these kinds of business ventures.

Although, the growth of these websites is directly linked to the growth of Internet and its applications, they should also be given credit for fueling the growth of cyberspace. This is because these kinds of websites make it easier for a budding entrepreneur with new ideas to implement his or her ideas which, in turn, hold the potential to encourage other entrepreneurs. Therefore, this situation, here, is highly symbiotic with Internet's expansion supporting the growth of script resource websites and vice versa. Consequently, in order to keep the growth of Internet constant, the growth of these websites also takes on more significance.

Computers have various components, and the computer case is what holds them all together. These cases have changed over the years but remain the central part of any PC. By understanding the cases and how they integrate with the other components, one can better understand computers.

Computers have a number of major parts. The computer case is what houses all the internal components of a computer. Within the case, the motherboard is the single largest component. Attached to it are the CPU (a microprocessor) and the memory (RAM). Ethernet capabilities (for internet connectivity) are usually integrated directly into the motherboard. Other major components inside the case include the optic drives (such as DVD), hard drives for data storage and the power unit.

To connect the computer to peripheral devices, the sound card, video card and cards for USB and other connecting ports all attach to the motherboard. Typically, these peripherals are the monitor, printer, keyboard, mouse and any other devices that need to be connected to a PC.

The optical drives are located in the front of the computer case along with the additional USB ports for easy accessibility. The other peripherals of the computer usually connect through the back of the case.

This case is the largest part of the computer and is typically constructed mainly out of a steel or aluminum. Plastic and acrylics are also used, but their purpose is usually just to enhance the design or look of the case. Much of the weight of the computer (apart from the monitor) is in the case so one should consider its weight and avoid those with sharp, dangerous edges when purchasing. Edges that are beveled or finished are much safer.

Other materials also used to construct computer cases include plastic, Plexiglas, wood and, believe it or not, even Lego blocks! Computer cases have also been referred to as the computer chassis, cabinets, boxes, enclosures, towers or simply just the CPU cases.

When the PC first came onto the scene, the case was horizontal with the monitor being placed on top of it. This design of the case had the power switch behind it with all the ports also placed behind the case. This was a pretty awkward (some would say incomprehensible) position because the operator had to get up and reach all the way behind the computer to switch it on.

When the vertical computer case came on the scene, the monitor could be placed on the desktop with the vertical case (also called the "tower stand") below beside the desk. This was more convenient because it left more space on the desk while allowing the user to access the switches from the front panel.

Some computer cases have been growing smaller in recent years, but there is currently a limit as to how small they can get. While smaller cases are more compact, they often do not have enough space to allow proper cooling or for new devices to be added to the computer. Due to these factors, computer tower stands remain popular.

A DVR card is used in DVR equipment to store information and to help the equipment function. DVR stands for digital video recorder. A DVR has a host of functions for controlling digital media. Live TV can be paused; events, programs and movies can be recorded. There are playback features and a host of other up to the minute features available with a DVR.

Satellite and DVR

The satellite industry introduced its first DVR back in the nineteen nineties; they took off like rockets everywhere. Everyone wanted one and everyone got one. The DVR can record programs and movies directly from the satellite system; it requires the card that is validated by the satellite system before sending the signal through the DVR box. The card is used a security feature to make sure no one is getting anything for free. It is a computer coded card that can be read by the satellite system. The card holds account information, viewing preferences and a host of other information regarding the customer of the satellite company.

Cable and DVR

Cable companies soon followed the satellite companies in offering DVR boxes with their services. The cable boxes that have DVR capabilities also use a card to share information and to make sure the service is being paid for. Without the card in place and being legitimate the cable will not feed a picture through to the TV set.

Where Does a Card Come From?

It is usually part of the satellite install or the cable install. It is placed in a specific spot on the DVR box and information is immediately uploaded to the server from the card, this information will tell the satellite or the cable company's server exactly what programming packages were picked and other pertinent information. Every once and a while the card will have to be replaced either as part of normal maintenance activities or because there has been some system upgrades requiring the card to be changed. If the card has to be changed out as part of a normal system upgrade or as part of periodic maintenance than the cable or satellite company will send a new card with instructions on how to change it out. If the card picks up a virus or somehow stops suddenly working, than a call to the cable or satellite company is warranted and they will send out a new one. There will be no service until the new one is installed.
