Keep your laptop cool

Keeping your laptop cool is essential to lengthening the machine's life. Laptops may overheat for several reasons, the most prevalent being because it is dirty or the fan has malfunctioned. Overheating frequently can cause internal damage to your laptop's motherboard and prevent the computer from functioning properly or at all. Implement these techniques to keep your laptop cool.



Steps to Follow

• Place your laptop on a towel on a solid surface when it is on.
• Alternatively, clean out any dust inside. Start by carefully removing the screws from the bottom of the laptop and setting them aside. Do not lose or drop them.
• Remove the face cover from the unit's CPU . Set aside.
• Using your pressurized computer air duster (or hair dryer), clean and blow out all of the dust inside the laptop. Make sure you get in between the blades of the fan and other hard-to-reach places. Screw the bottom of the laptop back on.
• A third option is turning your computer on and setting a desktop fan next to the side of the computer with the vents and the internal computer fan. This helps keep the entire system cool.

Steps to Upgrade a Computer

The demands of computer software only rise with time, and if you have an older machine, you may no longer be as happy with its performance as you once were. It is time for an upgrade. However, the process of upgrading a computer can be daunting for those who do not do so regularly. 

Locate Bottleneck

Analyze the performance of your computer to determine the component that creates a performance bottleneck. For example, the video card is the primary component that influences the performance of games, while the processor influences tasks such as video rendering and file compression.

Research Upgrade Process

Learn the process for installing the type of component that you are considering purchasing. Generally, the process of upgrading a desktop computer is similar from one computer model to another. However, notebook computers can differ greatly. Locate the service manual or disassembly instructions for your computer and determine whether the upgrade process is within your skill level.

Select Component

Perform research to select the brand and model of the component that you want to buy. Many processors, video cards, hard drives and other components are available to choose from. Narrow the search by first determining which components are compatible with your computer. For example, if your computer uses DDR-2 SDRAM memory, you can only upgrade the computer with DDR-2 SDRAM with the same rated speed or faster.

Purchase Component

Buy the component after locating a merchant that sells it at a reasonable price. If you can find the component at a local shop, you can purchase it and upgrade your computer without delay. However, if you search for merchants online, you may be able to purchase the same component at a lower price.

Print Upgrade Instructions

Print the service manual or disassembly guide for your computer before beginning the upgrade, unless you have a second computer that you can view the instructions on. If you have only one computer, you may otherwise experience frustration if you encounter a problem during the upgrade and cannot view the instructions.

Perform Upgrade

Install the new component in your computer. Open your computer only with the power turned off. If you have a notebook computer, remove the battery as well. Follow the disassembly instructions carefully, and avoid touching any component that you are not familiar with.

Differences Between Regedit and Regedit 32

Microsoft's Windows NT-based operating systems include two utilities for editing the registry, Regedit.exe and Regedt32.exe. While each performs essentially the same functions, there are subtle differences between the two that may have varying levels of importance depending on the specifics of your administrative computing needs. 

Compatibility with Different Versions of Windows

Regedit is available in all versions of Windows since Windows 95, while Regedt32 is only available in Windows NT, 2000, Windows XP, and Windows 2003. Also, Regedit is a 16-bit Windows application, while Regedt32 is a 32-bit Windows application.

Value Type Handling

Both Regedit and Regedit32 handle simple value types, such as REG_DWORD, REG_SZ and REG_BINARY. But Regedit32 also handles complex value types, such as REG_EXPAND_SZ, REG_MULTI_SZ, REG_RESOURCE_LIST,

REG_FULL_RESOURCE_DESCRIPTOR and REG_RESOURCE_REQUIREMENTS_LIST.

Importing and Exporting of Registry Files

Regedit allows for importing and exporting of text-based registry files, while Regedit32 permits only exporting of text-based registry files, but does support importing and exporting of binary registry files.

Executable File Location

The executable file location for Regedit is at %WinBootDir%, which is typically in the Windows directory on the "C:" drive. The executable file for Regedit32 is located at %SystemRoot%\System32, usually in the winnt\system32 directory on the "C:" drive.

Security

Regedit32 offers the option to support Read-Only and Permissions security modes, while Regedit has no security options.

Key and Value Searches

Regedit supports both key and value searches, but Regedit32 only permits key searches -- it does not allow value searches.

Barebone Kit

A barebone computer is a partially assembled platform or an unassembled kit of computer parts allowing more customization and lower costs than a retail computer system. They are available for desktop computer, notebook and server purposes, and in nearly any form factor. Manufacturers are also able to produce systems of a specialized or non-standard form factor, since the system is sold as a pre-built unit, with the motherboard and power supply already installed. 

Standard Barebone Components

Barebone kits usually consist of the components necessary to build a basic computer. These include: motherboard, graphics card (if one is not integrated on the motherboard), system processor, heat sink and cooling fan, memory, case, power supply, hard drive, optical drive, cables and mounting hardware. When assembled, these pieces constitute a basic computer. Unfortunately, they do not constitute a functional computer.

Other Essentials

Basic input and output methods are necessary to interact with a computer -- in this case, a keyboard and mouse for input and a monitor for output. In order to get the computer to do anything, you will also need an operating system. While several Linux distributions are available at no cost, any version of the Windows operating system requires an additional investment.

Some Assembly Required

Remember, this is a kit. A few simple tools and labor are required. In most cases, assembling a barebone computer kit is simply a matter of mounting the motherboard in the case, inserting the system processor, mounting the cooling fan and heat sink and installing the RAM. Once these components are in place, mount the hard drive and optical drive.

Advantages

Building a computer from components allows you to reuse older compatible components. When the motherboard from an older computer fails, there is no need to throw the entire computer in the recycling bin. Other components may still be usable in the new case. Drives, graphic cards and memory are all components that can be given new life on a compatible motherboard. Customization is another benefit of building your own computer.

Computer Won't Power on But the LED Power Is Lit on the Board

When the computer won't turn on, but still LED light lit on the motherboard, here are the potential causes. If there is beeping sound while starting the system, reference the motherboard manual; those beeps will indicate the problem.

RAM

Improperly seated RAM will cause the system to not turn on. This is because RAM is integral to the computer's operation. Turn off the system and unplug the power cord, then re-seat your RAM modules.

CPU

Reseat the CPU. Make sure no pins are bent and that it's sitting properly in its slot. CPUs lock into the motherboard. Reapply any thermal paste before remounting the heat sink.

Motherboard

If all else fails, the problem could be the motherboard. Getting a faulty motherboard is not unheard of. This is typically the last resort; this should be done only if all the above steps are exhausted.http://hardwaretexpert.blogspot.com/2010/10/different-types-of-rams.html

What Causes Error 633?

 

Error 633 is an error message that typically appears when attempting to set up or connect to the Internet with your computer's modem. Although it can prevent you from accessing the Internet, the issue is well documented.

Indications

An error message is displayed that reads either: "Error 633: The modem is not installed or configured for Dial-Up Networking. To check your modem configuration, double-click the Modems icon in Control Panel" or "Error 633 - the modem (or other connecting device) is already in use or is not configured properly." Windows will usually list the device as installed and working properly, but the error message is displayed when the modem is used to dial out.

Possible Causes

A missing or damaged Telephon.ini file or an absent or corrupted Telephony Application Programming Interface service provider registry entry can cause error 633, according to Microsoft. The error also can result from users attempting to establish more than one simultaneous broadband connection with a single modem, or other applications like fax or voice software using the modem. Error 633 is also caused by outdated software, conflicting with Windows XP modem drivers.

Solution: Repair missing/corrupted files and registry entries

To resolve a 633 error, first check to ensure no other applications are using the modem. Press "Ctrl," "Alt" and "Delete" to enter the Task Manager and scan the list of running programs. Terminate any that might be using your modem. Find out if the Telephon.ini file is missing or damaged by clicking the "Start" menu, selecting "Find," and checking the box labeled "Files" or "Folders." Enter "telephon.ini" into the Search field and click "Find." If the file is present, rename it to "telephon.old." Click the "Start" menu, select "Run," type in "tapiini.exe" and hit "Enter." Restart the computer.

            If the error message persists, use the registry editor to determine the status of the TAPI service provider entry key. Click the "Start" menu, select "Run," type "regedit" and press "Enter." Navigate to the following registry key:

            HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\Current Version\ Telephony\Providers
