How to build a desktop computer (part 2)

Fixing processor in processor socket on the motherboard

Take the motherboard and place on any soft surface such as cardboard. All new motherboards have a plastic cover placed on processor socket.

Release the lock handle to open the lid of processor socket.

Now remove the plastic cover fixed to lid. After removing the plastic cover the processor socket has to look like this.

Now we have to place the processor in processor socket

 

Most of the recent processors come without pins. Handling the processor is very delicate. Do not hold or put your fingers in the middle of the processor. Hold the processor as shown in the image

Always remember the portion which has the name and the speed of the processor (For example: Intel Dual Core 2.8 Ghz) must be on top. Look at the sides of the processor where you can see small cuttings on both the sides.

You have to look for the same small notches on the motherboard and place the processor properly.

Now close the lid and press the lock handle down and fix it to lock the processor to the motherboard. Make sure that your processor is placed properly in the motherboard processor socket before locking the lid.

Processor fan will have four locking clips which have to be fixed to the motherboard.

On the motherboard you can see four small holes present around the processor socket. Place the processor fan on the top of the processor and push the four locking clips one by one to the holes present in the motherboard to firmly lock the processor fan. If the locking clip is not firmly fixed then remove the locking clip by rotating anti clock wise. You can see a directional image on the locking clip to lock and unlock.

Processor fan comes along with four pin power supply wire.

After fixing the processor fan, you have to plug the processor fan power supply wire to the motherboard for proper running of the fan. Look in the motherboard for the name " CPU_FAN " or  " CPU FAN " near to the surrounding area of the processor socket.

You have to plug the processor fan four pin power supply wire to the port called  " CPU_FAN " or " CPU FAN " on the motherboard.

How to build a desktop computer (part 1)

Assembling a computer is very easy provided need to be bit careful while giving power connections and fixing peripherals to the motherboard. I will explain in detail how to assemble a desktop computer.

REQUIREMENTS :

(1) MOTHERBOARD

You can choose INTEL, GIGABYTE, ASUS, MSI and many more depending on motherboard features and obviously your money limit). I personally recommend INTEL

motherboard.

(2) PROCESSOR

Processors depends on the speed (Example: 2.8Ghz (Giga Hertz), 3 Ghz, etc). You have INTEL and AMD processors available in the market. I recommend if you are looking only for gaming purpose, you can choose AMD. Please note that when purchasing processor, whether INTEL or AMD make sure with the vendor that the processor supports the motherboard which you are planning to purchase.

(3) RAM (RANDOM ACCESS MEMORY)

RAM is available in different types like SDRAM, DDR1, DDR2, DDR3. Some motherboards support only DDR1 and some DDR2 or DDR3. So make sure that the RAM you purchase supports the motherboard.

(4) CDROM /DVD-RW /COMBO DRIVE

Many brands are available such as LG, SAMSUNG, LITEON etc.

(5) HDD (HARD DISK DRIVE)

Many brands are available such as SEAGATE, SAMSUNG, WESTERN DIGITAL etc. There are two types of HDD available. They are IDE HDD and SATA HDD which can be fixed inside cabinet.

(6) ATX CABINET

Cabinet is a metal or metal coated box where you fix motherboard and all other peripherals related to computer.

(7) SMPS (SWITCH MODE POWER SUPPLY)

SMPS is the power supply where you connect the computer from main power supply using power chord.

(8) MONITOR

This is an output device available as two types. One is CRT and the other is LCD. CRT monitor is heavy when compared to LCD monitor.

Note: Always remember to check with vendor for compatibility and support of any hardware peripherals with motherboard you purchase.

Cannot open BIOS for changing the settings

If you want to install operating system through bootable operating system CD/DVD and you are not able to make any changes in BIOS like changing the first boot sequence to CD/DVD drive, then you have to first clear or reset the BIOS settings to factory default and make any changes you desire.

Procedure:

Switch of the computer. Open the CPU cabinet and look for the battery placed on the motherboard. 

 Remove the battery and switch on the computer. Now you should be able to see " CMOS ERROR " press F2 or F10 or DEL to enter BIOS. The error message varies depending on the manufacturers of the motherboard and BIOS. Switch off the computer now and put the battery back to motherboard and switch on the computer and press F2 or F10 or DEL to enter BIOS depending on your BIOS manufacturers. You should now be able to make any changes to BIOS. Remember, any changes made to the BIOS will not be saved if there is no battery placed on the motherboard.

How to repair corrupted system files in Windows XP

There are numerous ways to fix corrupted system files in Windows XP like:

Starting the computer by selecting CD/DVD drive option as first boot sequence in BIOS. Insert operating system CD/DVD into CD/DVD drive and select “ R” option to repair corrupted files during the Windows XP operating system installation.

If the operating system is already installed, then boot the operating system and insert operating system CD/DVD into CD/DVD drive. Click on START Windows XP installation and select UPGRADE instead of FULL INSTALLATION option and click NEXT to continue operating system installation. If FULL INSTALLATION option is selected then all existing user files and folders including operating system files and folders will be deleted. The option FULL INSTALLATION is considered as new installation of operating system.

The easiest way to repair corrupted files is to boot the already installed Windows XP operating system. First insert operating system CD/DVD into CD/DVD drive then hold the WINDOWS key and press R to open RUN window or go to START and click on RUN to open RUN window. Type " SFC /SCANNOW " without double quotes and press ENTER key to fix all corrupted files on Windows XP. SFC (SYSTEM FILE CHECKER) is a DOS command utility to check and repair system related files. There are many parameters that can be used with SFC command. For more parameters hold WINDOWS key and press R to open RUN window. Type " cmd " without double quotes and press ENTER key to open DOS window. At the command prompt type " SFC /? " without double quotes and press ENTER key.

Note: Always use original operating system CD/DVD for good and better performance. With original operating system installed, you will have many featured enabled like WINDOWS UPDATES thus making your computer fully secure from software bugs.

How to access remote computer's drives and folders from your computer through RUN window

For example if you have three computers connected to network (A, B, C) assuming A, B, C are the names of the computers and you want to access " D "drive of computer " B " from computer " A ". The procedure is

Go to START and click on RUN or hold the WINDOWS key and press R to open RUN window. Type

" \\B (computer name of computer B) or IP address of computer B\D$ " and press ENTER key. If assigned any administrator password a window will popup asking username and password of computer " B ". Enter the username and password and press ENTER key to open Drive D of computer B.

It should look like " \\B\D$ "

If you do not know the IP address of the remote computer, hold the WINDOWS key and press R to open RUN window. Type " cmd " and press ENTER key to open DOS window.  In the DOS command prompt type " ping <computer name> ". In the above example type " ping B " and press ENTER key to get the IP address of the computer " B ".

 

In the above image I am pinging the remote computer ANIL to get the IP address.

There is another way to access remote computer through WINDOWS EXPLORER. Hold the WINDOWS key and press E or hold the WINDOWS key and press R to open RUN window. Type

" explorer " and press ENTER key to open WINDOWS EXPLORER. In the ADDRESS BAR type

" \\B\D$ "
