Windows 7 - Windows 7 Tweak Back on Track Easily and Quickly

As a hottest operating system, Windows 7 was released on 22nd October 2009. You might hear a group about Windows 7 tweaks in recent times. Microsoft said it run quicker than any other operating systems in the long-ago. But it doesn't meat that you don't need to tweak Windows 7.

I have weathered several versions of Win 7 on desktops and laptops around my real store for days. And I found some guidelines are very good for computer performance. So you can follow me easily if you have time.

Here are 3 tips:

• Removing needless Start-up things and Services - There may be a group of programs and services that are started automatically when your computer boots. They will palpably increase in length computer boot up time! Removing not needed start-up bits and pieces and services can tweak Windows 7 boot faster as fly.

• Defragment Your Hard Drive Regularly - When hard drive is fragmented, files are saved in lots of blocks. This means they have to be searched and place together before being used. If you execute a defragment program on your system repeatedly, all the blocks are placed together, after that to each other. This be able to improve computer performance apparently.

• Scan and Fix Registry Errors recurrently - This is one of the most excellent tweaks for Windows 7. As a data base, registry records all hardware information, software information and users' operations. After a while, it will become overstaffed and cause many errors. Of course, the computer performance will be significantly decline by these factors. So don't forget to maintain your registry recurrently!

Gigbayte Motherboards

Nice Quality Difference Of Gigbayte Motherboards If you are looking for a motherboard with an outstanding price, quality components, and a support team you can count on look no further than the motherboards from Gigabyte. I have used Gigabyte motherboards in a variety machines and have had great success with all of them. They have an over 20 year track record of high quality, top of the line motherboards. Recently they have begun to add more value driven products to their line card. These products have the same high quality of the top end motherboards, but come at a price that anyone can now afford.

Founded in 1986, Gigabyte has continued to grow year after year with sales topping 19 million products in 2008. Originally their major customers included Alienware and Falcon Northwest. Alienware is a premier gaming system manufacturer that was purchased by Dell in 2006. They now are the premier gaming brand for the largest computer manufacturer in the world. They still continue to use Gigabyte motherboards heavily and rely on them for their performance and dependability.

Gigabyte motherboards can work with both Intel and AMD processor chips. While these chips are not interchangeable, there are comparable models that can mount either manufacturer's chips. They currently manufacture motherboards that support the Intel Socket 1366, 775, 479/437, 478 and M chipset configurations. For AMD Gigabyte motherboards can support Socket AM2, AM2+, and AM3. All of these range from the newest chipsets to chips far older. They also can support a wide range of RAM types from low end budget RAM to high end overclocked performance RAM DIMMS. Before you purchase make sure that your motherboard will support the RAM that you are getting. If the RAM does not appear on the approved list, contact Gigabyte to see if whether they intend to test with that type. Many of the motherboards also have extensive options as far as upgrade slots are concerned as well. This combination of options for their motherboards means that you can find the exact right fit for your needs.

One of the biggest things that separates Gigabyte motherboards from the competition is the quality of the components that they use. There most recent innovation is the use of 2oz copper PCBs in all of their motherboards. While this may not seem like a big deal, for those that are focused on the quality of their computer components it is. As computer processors and other components have become faster and faster, they also have become hotter and hotter. While heat sinks and other components have been designed to compensate for this heat, the actual PCB for the motherboard has not. Gigabyte is the first to introduce dual copper layers for the PCB on desktop machines. What this means to you is that the Gigabyte motherboards are much more capable of distributing this excess heat. Less heat into the components means a longer life span, better performance, and overall considerably less wear and tear on the products. These new motherboards promise to be more reliable, more stable, and have a longer shelf life than any other products on the market today. With their wide range of choices and dedication to quality it is easy to see why Gigabyte sold so many motherboards in 2008

Computer security

Computer security is a branch of technology known as information security as applied to computers and networks.

The objective of computer security includes protection of information and property from theft, corruption, or natural disaster, while allowing the information and property to remain accessible and productive to its intended users.

The terms computer system security, means the collective processes and mechanisms by which sensitive and valuable information and services are protected from publication, tampering or collapse by unauthorised activities or untrustworthy individuals and unplanned events respectively.

The technologies of computer security are based on logic. As security is not necessarily the primary goal of most computer applications, designing a program with security in mind often imposes restrictions on that program's behavior.

There are several approaches to security in computing:

1. Trust all the software to abide by a security policy but the software is not trustworthy .

2. Trust all the software to abide by a security policy and the software is validated as trustworthy .

3. Trust no software but enforce a security policy with mechanisms that are not trustworthy .

4. Trust no software but enforce a security policy with trustworthy mechanisms.

Intel Graphics Media Accelerator Series GMA

Intel Graphics Media Accelerator GMA 4500MHD

Intel Graphics Media Accelerator Gma 4500MHD sometimes also called GMA X4500 HD or other combinations is a DirectX 10 capable onboard graphics adapter in the GM45, GE45 and GS45 chipset of the Centrino 2 platform (Montevina).
The chip has no dedicated graphics memory, but takes dynamically an amount from the main memory (up to 384 MB).

Compared to the predecessor GMA X3100, the GMA 4500MHD has two more shaders and a 33 MHz higher core clock speed. Therefore, the chip is noticable faster than the older one (especially in 3DMark06). Still, the performance is just on par with the entry level dedicated graphics cards and therefore not suited for demanding games. Some older games like Fear can be played in low details and low resolutions (see "Gaming Performance" below).

Compared to other modern integrated graphic cards like the Nvidia GeForce 9400M (G 102MNVIDIA GeForce G 105M) or AMD ATI Radeon HD 3200, the GMA 4500M HD noticably slower and provides less optimized drivers for games.

The version in the GS45 can be clocked lower (320 versus 533 MHz) and support only FSB 800 (instead of FSB 533/1066). Furthermore, switchable graphics are only supported in the GM45 chipset. The GE45 has the same features as the GM45, and aditionally is certified by Macrovision.

A new feature of the GMA chip, are the integrated HD video-decoding functions. The GM45 is able to decode HD-videos in the formats AVC, VC-2, and MPEG-2 to help the CPU. This way a Blu-Ray playback should also be possible with a low end CPU (only with the 533 MHz clocked version in the GM45 and GS45).

The graphics core in the GL40 and GS40 chipset with a lower core speed of 400 MHz is called GMA 4500M (without the HD). Because of the lower clock rate, the 4500M performs a bit worse in games and is not capable of decoding Blu-Ray videos fluently.
