Consider a Red Sox-Yankees match up in the playoffs and you pretty much capture the spirit of what took place on April 2 when rivals Nvidia and AMD / ATI both launched mid-priced, performance video cards on the same day. Although each team sent their sluggers in to swing for the bleachers, Nvidia edged out the competition with its GeForce GTX 275 when measured against ATI’s Radeon HD 4890.

Nvidia aimed the newest addition to the growing GeForce family at the sweet spot between the GTX 260 and the GTX 285, but buyers get some serious value in the deal. The GTX 275 is based on NVIDIA’s 55nm GT200b GPU, essentially the same one used in both the dual-core GTX 295 and the GTX 285. Hosting a massive 1.4 billion transistors, the GPU has been tweaked for the GTX 275 and serves up a graphics clock spinning at 633 MHz and a processor clock tripping the radar at 1404 MHz. Translation: the GTX 275 is sporting some serious muscle often found on more expensive hardware.

Add to this the fact that the GTX 275 uses the same dual-link DVI outputs and HDTV output as the 285, the 275 also marks the launch of Nvidia’s version of Ambient Occlusion (AO) – a new feature of the Release 185 graphics drivers. Ambient occlusion adds additional realism by mimicking the way light radiates in real life, factoring in how objects relate to each other. AO demands a high processor load – performance can plummet by as much as 20% – but the effect can be dramatic, particularly in games deploying low light or indoor situations.

Roll in Nvidia’s usual suite of proprietary technologies such as GEForce 3D Vision, PhysX, and CUDA and add compatibility with Microsoft’s DirectX 10. Since it hardly breaks the the bank at around $250, the GeForce GTX 275 is a great addition to Nvidia’s fleet of mid-priced graphics cards.

What is Hard Drive PCB?

The green board on the bottom of the hard disk drive is known as Printed Circuit Board(PCB). The main function of the PCB is to supply power to the hard drive, maintain speed and rotation of the spindle, and control all internal operations through its firmware. Essentially, PCB is the brains of the hard drive that all components are heavily dependent upon.

Why Swap PCB Boards?

Hard disk drives that do not spin up after the power has been supplied can be diagnosed as PCB failure. Because data recovery service is very expensive, sometimes we would prefer to swap them ourselves.

How to find the matching HDD PCB boards?
Western Digital – same board number which is etched on the PCB, begin with 2060- Seagate – same board number which is etched on the PCB, begin with 100…, and the same Main Controller IC. If you can’t find the number on the PCB (Old Models), you should find the same Main Controller IC. Maxtor- same Main Controller IC(The biggest chip on the board) Hitachi- same information on the small white label (first two lines) Samsung – same board number which is etched on the PCB, begin with BF41- Fujitsu – same board number which is etched on the PCB, begin with CA

Hard Drive PCB Swap Process:

Remove the PCB from both hard drives with star screwdriver. Replace the damaged PCB with replacement one. If you HDD spins up, but can’t be recognized, you should also exchange the BIOS chip on it. If there is no matching 8pins BIOS chip on the PCB, it means the BIOS chip is integrated on the Main Chip IC, then you should remove the damaged PCB’s Main Chip IC to the donor PCB. It is more complex to exchange the Main Chip IC than exchange the BIOS chip. If you should do, please do several test on the PCBs which don’t have the important data.

What is PCB’s BIOS Chip?

All of the 8pins (4 pins on each sides) with 25P05VP, 25P10VP, 25F512, 25F1024, 25F1024AN, SST25VF512, SST25VF010, etc. are the BIOS chip. It is easy to be found because there are not many 8pins chips on the board.

In most cases, you should exchange the BIOS before you swap hard disk pcb. You should have certain technique.

Note: You should know the hard drive failures are not always caused by PCB failure, swap PCB can’t guarantee to fix all of the hard drive problems.

A laptop is essential for students and working individuals. Because of its portability, users can write important papers, connect to the Internet via wireless modems, and can even watch movies anytime and anywhere. But without proper care, this machine can break down, and especially, there can be problems with the LCD monitor. Here are some tips that can help you in troubleshooting your laptop’s LCD monitor.

Is there something wrong with your screen? If this is so, then there is a possibility that the LCD (liquid crystal display) backlight of your laptop is broken. The LCD backlight is the source of light that gives you a clearer visual of your screen. Symptoms of LCD damage include:

- Dim laptop LCD

- Flickering screen

- Faint images on your LCD

- No video image

- Faded laptop LCD

A laptop backlight is composed of four parts and these are:

- Laptop inverter

- LCD lamp

- Inverter cable

- Toggle switch

Damage to any of these parts may result to the symptoms stated above. Unfortunately, there is no other way to be sure if one of these parts are damaged without using a tester. Some of the main causes of damage to these parts include age and excessive use of your laptop. Parts such as the LCD lamp usually last for two years minimum.

Aside from the blacklight, it is possible that your LCD screen itself is damaged. This problem can be very serious because the LCD is the most fragile and expensive part of your laptop. Symptoms of LCD damage include:

- Decolorization of your screen

- Appearance of stripes or lines on your screen

LCD damage is usually caused by hard impacts to your laptop. Remember, the LCD is a very sensitive and fragile piece of equipment. Even the slightest amount of pressure on your LCD can cause it to break.

The only way to repair the backlight and the LCD monitor is to replace them. Replacing the LCD monitor alone can cost you around $250 and that is apart from the $120 service fee that most laptop repair companies charge.

Dells extensive desktop family now includes the new Inspiron 518. Backed by the Dell name, quality, and power, this mini tower desktop provides high performance for any type of user. With a shiny black casing and beautiful chrome accents, this desktop can make any office or room look a bit more exotic. The Inspirons budget, along with functionality, is geared a bit more towards families and students than those techy individuals out there.

The bare-bone system starts are $329. (Bare-bone, in this sense, means the minimal technical specifications discussed in a bit.) Additional features can be added through Dells interactive build process. The Inspiron 518 may not be the cheapest desktop on the market, but is decently priced when you consider the performance and functionality that it offers.

Under the hood you will find a 2.4GHz Intel Core 2 Quad Q6600, 2GB 667MHz DDR2 SDRAM, 256 ATI Radeon HD 3450, and a 320GB 5,400rpm hard drive. The Inspiron 518 also has gigabit Ethernet for fast connection speeds, dual-layer DVD burner, and operates on Windows Vista Home Premium SP1 (32-bit).

Notice that there is no option for the installation of the 64-bit version of Windows Vista. Unfortunately, the Inspiron 518 is not flexible in this sense, as it only supports a 32-bit operating system. 64-bit operating systems require more memory, which this system does not have. If you are planning to upgrade to Windows 7, you will first have to upgrade the memory, and any other necessary hardware, to get the desktop up to speed to handle a 64-bit OS.

The overall design, of the Insprion 518, is quite sleek and easy on the eyes. Dell did not stop with the overall appearance; they actually added a tray, to the top of the mini tower, for easy storage of small plug-n-play devices. Additionally, there were two USB 2.0 ports added, near the tray, to allow users to conveniently charge and connect with these devices.

Dell provides consumers with friendly interfaces and easy navigation. To increase the user experience, they have now added what is called the Dell Dock. Similar to Vistas sidebar, you can customize this dock to hold icons for your favorite applications and files. This gives you easy one-click access to those things you use most. You can customize where the dock appears, on your desktop, along with the option to completely shut it off.

The Dell Inspiron 518 does not offer consumers the option to add a Blu-ray optical drive. Depending what you had in mind for the desktop, this may not be a hindrance at all. The graphics card, which comes with the system, is a bit on the low end as well. Unlike other Dell machines, there is no option to upgrade this feature upon customizing your build. The graphics card that comes with the Inspiron 518 is decent, but is not a high-end card for gaming.

The Inspiron 518 is a budget friendly computer. Combine this with its high performance and the number of features it offers, and you’ve got yourself an amazing everyday computer. Whether you are looking for a computer for a student or an entire family, the Inspiron 518 is a good fit.
