South Bridge is also called ICH or input-output controller HUB. System will be dead if there is any fault in South Bridge. In this post I will explain how to confirm that south bridge or ICH is faulty in a desktop motherboard step by step.
Desktop computer contains two main chips on motherboard. These two chips are called chip set. Chip near the processor socket is called North Bridge or Graphics and Memory controller HUB(GMCH) or System controller Hub. North Bridge mainly does processing and Display related job.If there is a no-disply problem in the motherboard, north bridge may be faulty. But other faulty components can cause the same problem. So, how do you confirm that north bridge is faulty?

For replacing or upgrading your desktop RAM, it’s very important to know what kind of RAM it is currently using. You can know that by reading the nameplate sticker sticked on it or looking physically. Every type of RAM operates in different voltage levels and frequency . Here inn this post we will discuss them one by one.
RAM stands for Random access memory. It helps processor to fetch data randomly as well as very fast. It stores the data temporarily for current running programs.
Like different generations of computer there are different generations of RAM. We will discuss one by one.
Potentiometers varies potential difference between it’s terminals.It’s a very common and useful device used to vary voltage, current as well as gain in a circuit. Depending upon the physical size and form factor there are various types of Potentiometers.In this post we will differentiate potentiometers (in short POT) on the basics of Output Response with respect to angular displacement of the knob.
PGA (pin grid array) is one type of processor packaging which offers more pins than DIP( dual inline package ). It’s a square or rectangular shape package. Pins are arranged in a matrix like manner at the bottom side of the processor. Pins are generally spaced 2.54 mm (0.1″) apart, and may or may not cover the entire underside of the package.
After few month of buying a brand new laptop or PC, it seems to become slower day by day. Time delay is very annoying in this super fast society. In this post we will focus on the cause and solution of this problem.
