Tips to Upgrade Graphics Card

unduhanThe graphics card is also known as video card, graphic controller, graphics accelerator or display card. It is a PCB (printed circuit board) that has three major components. These components are video memory, video BIOS, and graphics processing unit.

The graphics card should be changed if it gives a poor performance or if you want more speed options for the computer games. In the first case, you need to verify that it is the reason for the poor performance and not the computer. To do this, use the scan disk or defragmentation options and look for bad sectors on the hard disk. You can also try using other ways to speedup your computer. If they do not work, you can conclude that the lowered performance is due to the faulty working of the card. Once it has been established that the graphics card is responsible for the low speed, you should upgrade it.

Some video cards are integrated in the motherboard and some are externally connected to the computer. Older versions of motherboards used a PCI (peripheral computer Interconnect) slot in order to plug-in

Guide to Choose a Good CPU Fan

Did You Know?
The latest in the world of CPU coolers is the heat pipe technology, and it is highly efficient.

The central processing unit (CPU) of your computer can generate large amounts of heat, which if not dissipated properly, can damage the internal components, rendering your computer useless. For the smooth functioning of your computer, you must ensure that you have a proper cooling system in place, that can effectively dissipate the heat generated and keep your system cool.

The cooling system for your processor consists of a heat sink and a fan. The fan is attached to the heat sink, which is a block with numerous fins. The heat generated by the CPU is dissipated by the fins of the heat sink, and the airflow created by the movement of the blades of the fan helps to speed up the process.

Choosing a Good CPU Fan

It helps to know that the heat sink and fan that come with a new CPU are mostly of average quality, and only do a fair job in cooling your system. If you want a computer that works silently, or if your computer has been overheating of late, then it’s

How to Choose a Graphics or Drawing Tablet

Who is the Leader?
Wacom is the market leader when it comes to graphics tablets. It offers 42 products and accessories, whereas all the other companies combined only offer 15. In 2013, Wacom had a market share of 92.3% in Japan and 80% in the rest of the world.
A graphics tablet is also known as a drawing tablet or a digitizer. It is an input device that replicates the act of drawing on a paper with a pencil or pen. But when you draw with a graphics tablet, a flat pressure-sensitive pad replaces the paper, and a stylus replaces the pencil or pen. We can use a graphics tablet to input hand-drawn illustrations, text, and also signatures. Once the input is captured, it is sent to the computer via an interface (mostly USB) where it is converted to digital format and sent to a CAD (computer-aided design) application for further processing.

In this article, we give you some tips to choose the right graphics tablet according to your needs.

Pointers for Buying a Graphics or Drawing Tablet

Tips to Access Your Computer’s BIOS Setup

What happens when you turn on your PC? Lights come on the keyboard and monitor, the computer’s brand logo may appear on the screen, then the operating system loading message appears. This is all occurring on screen, but in the background, your computer is actually powering on and preparing its external and internal parts. Many assume the Operating System (OS) is the first program a computer loads and operates on but the actual start-up program is the BIOS.

BIOS stands for Basic Input/Output System, which is inbuilt in every PC during manufacturing and is loaded, run and executed when you press the power ON button of your PC. The BIOS is a sort of firmware interface for a computer. Different components, such as pen drives, graphics card, keyboard and mouse and disc drives attached to a computer, need to be initialized and identified to the computer. The BIOS does this in the form of a check-list (“turn USB ports on”, done) and this procedure is known as POST (power-on self-test). The operating system itself is a program, which needs to be loaded and executed. This too is performed by the BIOS, which locates the OS program on the computer’s

Odeas to Buying a Webcam

Ways to Easily Update your Computer’s BIOS

BIOS stands for Basic Input/Output System, and it is typically a software that is embedded on the motherboard of a system. It controls the hardware such as disk drives, keyboard, mouse, display settings, pen drive etc., that are attached to it, and sends the information to the Operating System (OS) of a computer. Motherboard is the center of coordination in a computer that unites the hardware of the system and enables communication between each other. Any upgrades that are required in a computer depends on the type of the motherboard and its inbuilt features.

What is Computer’s BIOS?

The computer’s BIOS is basically an EEPROM, which stands for Electrically Erasable Programmable Read-Only Memory. EEPROM is a non-volatile memory which means that, the information which is stored can be retained later even when it is not powered. EEPROM can be modified by the user, and can be erased and reprogrammed. Most of its components are not serviceable, as it is soldered to the motherboard. The firmware i.e., the coded instruction in the BIOS can be updated or upgraded. In modern computers, it is inbuilt on a chip called CMOS, which stands for ‘complementary metal oxide semiconductor’. The common type of EEPROM

Guide to Install a Liquid Cooling System

Liquid cooling systems have been used to cool cars since eons and seemingly, it also happens to be the way to cool your computer. Yes, it is true that computers today are designed to emit less heat, but integrated circuits are integrated circuits; they are bound to radiate heat in generous proportions. The joys of overclocking are way too many to be caged under the restriction of heat generation. Having yawned over air coolers, it is time to move on to a slicker option – that is liquid cooling.

Components of a Liquid Cooling System

The liquid coolant comes first, and a popular option is distilled water. Chemical additives (antifreeze solutions) give it that snazzy color and help lower the temperature of the water, increasing its effectiveness. An interesting variant is liquid nitrogen. With a boiling temperature of -196°C, it beats water in every aspect. But the recommended use of liquid nitrogen is strictly for smaller overclocking sessions. A reservoir is the tank that stores the coolant. You need a pump that helps the liquid to flow smoothly. This pump is available in variations that help you fix it outside the reservoir, or submerge it. The radiator is used to

Computer Hardware Basics

How to Repair and Maintenance Computer Hardware

What is computer hardware? Hardware components like the monitor, keyboard, CPU (Central Processing Unit), mouse, and other I/O (Input-Output) devices constitute a computer. The working of the monitor, keyboard, mouse, and I/O devices depends largely upon the CPU. Due to some minor causes, like loose connections or dust saturation, any of them can stop functioning.

Faults occurring in the CPU are most hazardous, as it has a very complicated structure. The CPU is an assembly of the motherboard, hard disk drive (HDD), random access memory (RAM), compact disc-read only memory (CD-ROM) drive, and the floppy drive. Unless you are well-acquainted with the CPU hardware, it is extremely difficult to pinpoint exactly where the fault has occurred. If any one of these components fail to perform, there are a few repair tips that can be followed. In order to view the circuitry inside the CPU, its casing has to be removed.

The entire functioning of the computer depends on this component. The processor chipset, that performs all the logical operations of the PC, is embedded in the motherboard. Ribbon cables, power supply, CPU, and RAM are the things to be checked first on the motherboard. Check if any of the
