Computer Beep Sounds

When we switch on the computer, at the Booting time BIOS will check the hardware parts whether all the parts are working or not. If any problems in hardware parts a “Beep” sound will occur in the PC.

We can find the problems by the number of “Beep” sound which comes from PC.

1 Beep sound - RAM can be damage when refreshing. To correct this problem, remove the RAM and fix it again properly.

2 Beep sounds - Something wrong with Battery Circuit. To correct this, remove the RAM and fix it again.

3 Beep sounds - In this stage the Base RAM would have damage. To fix this problem remove the RAM and fix it again, even though if it doesn’t work replace a new RAM.

4 Beep sounds - Problem with System Memory. To fix this problem, correct the System Board.

5 Beep sounds - In this situation problem occur in Processor. We have to check the System Board to fix this problem.

6 Beep sounds - Problem with “Keyboard controller” and “Gate A-20”. To fix this problem should correct the Keyboard Controller Chip.

7 Beep sounds - Something damage with “Virtual Mode Exception”.

8 Beep sounds - Problem in Display Memory area. 

To fix the both (7 & 8) Beep sounds remove the VGA Card and fix it again.

9 Beep sounds - Problem with BIOS Chip. To fix this, change the BIOS Chip in the Mother Board.

10 Beep sounds - Problem with “CMOS Shutdown Registry”. To fix this problem, correct the System Board.

Nonstop Beep sounds - Damage in Video Area. To fix this problem, remove the VGA Card and fix it again

How to Assemble a computer?

Note :
The people who are going to assemble CPU should consider on the following. Until you complete your CPU assembles fully, you should be responsible for CPU without receiving the main power supply. When your CPU gets power supply, it’s very dangerous to touch the assemble parts.
For any reason, you should not touch the power box which is inside the CPU case. Because power box has high voltage, even if there is no power supply. It’s very dangerous for your soul  
Before assemble the computer, you can recognize where the different parts are fixed.

The way of PC Assembling

Take the mother board carefully from the box and keep it in a safe place. Then, take the processor from its box. (Inside the processor box, there will be a processor and a fan)
Take the processor and fix it in the particular place in the mother board.

Next
Open the clip from the place where the processor is fixed and remove the processor cover, as shown in image below.

  

 

 Like this open the area of the fixed processor.

There are two bents in processor and also two bent in mother board, at the place where the processor is kept, connect the bents carefully and fix the processor into mother board.
If any problems in this, the mother board get damage. So be careful of the mother board.

Like the picture shown below fix the processor properly into mother board.

After fixing the processor, close the mother board slot door and lock the processor properly with the clip.

After that fix the processor fan at the top of the processor.

hile fixing the processor fan, you can see a lock like this at the back side of the mother board. This should get locked properly, so consider this also.

 

After, fixing the processor fan properly, also fix the processor fan pins into mother board as shown the below image.

Open the clips and fix the RAM in the particular place as shown in this image.
After fixing RAM in the mother board, press the clips with the hands and lock it.
If the RAM is locked with the clip properly, that mean you have fixed the RAM in the mother board correctly.

After fixing the RAM and the processor in the mother board, fix the mother board in the particular place which is shown by the arrow mark in this image.

Mostly CPU cover consists with power box, so no need to buy a power box separately. Next we are going to see how to supply the power to the mother board parts through this power box. To give power supply to the mother board parts, we should fix the power box pin properly. 

Your power box contains 24 way Connector pins. (The older power box contains only 20 way Connector pins. So that doesn’t suit for the new model mother board)

 

Your mother board contains 24 way pin slot. Connect the power box connector pins to the mother board 24 way pin slot correctly.
(Here I have marked with the red color, so connect correctly in this way as shown in image)

Next, connect the 4 way connector pin which is in power box to the mother board 4 way pin slot correctly. These two connector pins are very important pin types that connect from the power box to the mother board

I have shown you two places to keep your hard disk in CPU cover.
You can use either in any of this 2 way.

Check your hard disk type whether it is IDE or SATA. Select the correct pins and connect the hard disk to the mother board.

 

Then supply power to the hard disk using SMPS.
If your hard disk and DVD player are SATA type and if your power box (FNTS) doesn’t contain SATA type power pins, you have to buy two SATA type pin separately.

 

As I shown in image, remove the front cover of the CPU case and fix the DVD player. Then Connect either SATA pin or IDE pin & SATA power pin properly.

Then, the CPU front cover consists of power SW, reset SW, power LED, HDD LED and speakers. Fix the pins of these in to your mother board properly.

The mother board catalogue contains the details of “How to fix the pins”. If these pins are fixed properly, then only the mother board starts.

Until now the things you have completed

• Fix the processor in the mother board 
• Fix the RAM in the mother board 
• Fix the mother board in the CPU case 
• Fix the hard disk in to CPU case 
• Fix the DVD player in to CPU case 
• Fix the hard disk and DVD player to mother board with IDE or SATA pins 
• How to fix the HDD and power SW pins. 

IDE Type Hard Disk

 

Blue Color box : IDE pin slot
White color box : Power slot

SATA Type Hard Disk 

Every mother board contains a cover plate as shown in the image to fix with CPU case.

If you fix the computer assemble parts in the above mentioned methods, you’ll get a complete CPU. Fix the CPU with power cables and also fix with monitor.

If you have done all the steps correctly, you’ll get a complete computer. Install a operating system as you wish and start the computer.

Tips to buy Laptop

Now a day’s most of the people those who are using desktop computers are moving to Laptop. Laptops are more expensive than the desktop computer, so we have to choice the best Laptop while purchasing. So we people should have a knowledge about the Laptop, if we does not have the knowledge about Laptop we cannot choice the correct Laptops.

So let’s see what are the things to consider when purchasing a Laptop?

First of all we should decide the brand of the Laptop which we are going to purchase. To buy the best brand, choice any one of the brand from the below given brands.

SONY

HP

DELL

SAMSUNG

THOSHIBA

LENOVA

ACER

Then, from the selected Laptop brand we should consider the following things.

LAPTOP CONFIGURATION

Processor

Processor is a very important chip in the Laptop mother board. The best processor in the present market is Intel Core i7. After this Intel Core i5 and Intel Core i3 are next best processor. If you’re ready to purchase an expensive Laptop, first of all choice a best brand and then choice the one of the given below processor.

Intel Core i7

Intel Core i5

Intel Core i3

 

If you decide to purchase a cheaper Laptop than the above mentioned, then you can choice either one of the processor.

Intel Core 2 Duo

Intel Dual Core

If you select the lower quality processor than the above mentioned processors, it’s not suitable for the latest technology.

Next we should consider on Processor Speed. 1.60 GHz Speed and 2.0 GHz Speed processors are very slow. So choose 2.8 GHz speed or higher than this.

RAM

Next we should concentrate on RAM size. RAM size is responsible for computer speed, when we run more than 1 program at a time the computer will get slow. So if we want to run latest advanced programs, we should at least use 2GB RAM. If we have more than 2GB RAM your computer will have more speed.

Mostly latest laptop comes with DDR2 RAM, but DDR3 RAM is better than DDR2 RAM. 
So if you wish, you can replace DDR2 RAM to DDR3 RAM.

 HARD DISK

The Laptop which we are going to purchase should have at least a Hard-disk with capacity of 320GB. Because if we want to use the latest advanced software like Photoshop, CorelDraw we need at least 320GB Hard-disk. To save our data and files, we need this much of Hard-disk capacity. When selecting a Hard-disk, we must consider on Hard-disk Speed also.

The following Hard-disk Speeds are better to use in latest Laptop.
SPEED 7200RPM
SPEED 5400RPM

If your Hard-disk speed is less than above mention speed, select one of the Hard-disk from above mentioned.

DVD DRIVE

If you’re buying a branded Laptop you don’t want to care a lot about DVD drive. Because mostly branded Laptop comes with suitable DVD drive.

GRAPHIC CARD

When purchasing a Laptop the next important thing to consider is Graphic Card. It’s important because if you’re using Photoshop, CorelDraw, playing a video game or if you wish to watch HD Videos in your Laptop, you should have quality Graphic card. 


When you select a Graphic Card another important thing to consider is whether it is “Dedicated Graphic Card” or “Integrated Graphic Card”. 
“Dedicated Graphic Card” is much better than “Integrated Graphic Card”. If “Dedicated Graphic Card” is fixed in your Laptop, while playing high quality games the Laptop wont get slow.

OPERATING SYSTEM

Next select the Operating System for your Laptop. In the latest Laptops, mostly Windows 8 installed as operating system. But Windows 7 has different versions.

 

Windows 8 Enterprise

Windows 8 Professional

Windows 8 Starter version

 Select one of the above mentioned version. But 

“Windows 8 Enterprise” and 

“Windows 8 Professional” are the best, so choice either one of this.

Mostly latest laptop comes with Webcam, Mike but once again check whether these are available or not in laptop. And also check HDMI port, Memory card slot, Front mike, etc...
