MOTHERBOARD

Motherboard is called as mainboard.There are plenty of components in this motherboard.This motherboard plays the major role in the hardware components.

1.Motherboard AT(Advanced Technology) keyboard interface connected-5 pins


2.Motherboard AT Power supply connected-12 pins

3.EDO(Extended data output) RAM slot


4.SD(symchrome dynamic)RAM slot

5.Primary hard disk controller-40 pins


6.Secondary hard disk controller-40 pins


The Hard disk controller is used to connect the interface cable in the motherboard

In latest version of the motherboard, SETA cable controllers are used.

7.Floppy disk controller-34 pins


8.Printer controller-25 pins


9.mouse port-9 pins


10.modem port-9 pins


11.ps(personal system)2 port-5 pins


12.USB(universal serial bus)-8 pins


13.PCI slot(white colour)

This PCI slot is used to connect the VGA card,TV tunner card,sound card in   your mother board


14.ISA slot(Industrial standard architecture) (black colour)


15.CMOS(complementary metal oxide semi conductor) IC or BIOS(basic input output system) IC 


16.CMOS or BIOS Battery-3 volt

17.Processor socket

18.Transistor

19.Heat zink

20.Jumper


 Jumper settings is near the cmos battery.To clear the BIOS or CMOS settings password,date,time and to reset the BIOS settings,this jumper is placed alternatively and again replace to original position

 21.Front panel connection in motherboard

 Power LED-2pins
 Restart switch-2pins
 Power switch-2pins
 Speaker-4pins

 The Front panel buttons,speaker connection,Power LED all are given to the motherboard.There is the connection pins in the motherboard and that allows you to connect the panel buttons,speaker,power switch,power LED

Computer problems?

TROUBLESHOOTING IDEAS FOR YOUR COMPUTER PROBLEMS:

Many of us get headache with our system while its going into fault and many of them will be out of their mind.The problem with monitor,keyboard,mouse,operating system,hardware problems and most friendly viruses makes the user into tense and worry.

There are some possible solutions and answers to solve our own computer problems.The first thing is you need to be familiar with some of your hardware components like RAM,Processor,CMOS battery,Power and interface cables,SMPS and other basic things.Don't get anxious mind while your system goes into the trouble.Here there are some troubleshoots that going to make your system better in quality.


SYSTEM IS HANGING ?

Is your system is hanging? Don't look at them with staring eyes,its time to check some stuffs in your computer. 
1.Check the RAM.
2.Check the virus.
3.Check the processor cooling fan.
4.Reinstall the windows software or your own operating system .


SUFFERING FROM FATAL ERROR?

Fatal error makes many computers into shit.To avoid this fatal error, there are some steps below.
1.Check and replace your RAM.
2.Check the processor cooling fan.
3.Check the loose connection in the motherboard fittings and interface cable.
4.Reinstall the windows software or your operating system software


SYSTEM IS NOT WORKING or POWER LED IS NOT GLOWING?  

Don't blabber if your system is not working or your power LED is not glowing 
1.Check the power cable
2.Check the ON OFF switch present in your cabinet
3.Check the SMPS and its Voltage


IF THE FLOPPY DISK ERROR MESSAGE IS APPEARED IN THE MONITOR?

Sometimes it shows like drive error A: or floppy disk fails.To avoid this message
1.Check the CMOS or BIOS setup by pressing F2 and disable the floppy drive.
2.Check the floppy disk drive cable. 
3.Clean the floppy disk sensor using recommended solutions.
4.Replace the floppy disk drive.  


SYSTEM RESTARTS AT ANY TIME?

This happens to many of the users and make the many users to say jeez.Here the solution to solve this common problem.
1.Power cable may be in loose connection.
2.Check the RAM.
3.Check and replace the SMPS.
4.Reassemble the systems.
5.Check the power ON OFF switch and replace the switch.
6.Check the virus.


MOUSE IS NOT WORKING?

Mouse makes the user to use the computer in comfortable way.Sometimes this mouse also makes the user to worry by not working properly.Here there are some of the precautions.
1.Check the CMOS setup.
2.Check the mouse connection.
3.Reinstall the windows software.
4.Replace the mouse.


HARD DISK CONTROLLER FAILS?

To avoid hard disk and its controller problem,just check the following
1.Check the CMOS setup
2.Fit the new IDE card and disable the hard disk controller in CMOS setup


NO DISPLAY IN THE MONITOR BUT POWER LED IS GLOWING?

Sometimes power LED glows but monitor remains tranquil,to avoid this situation.
1.Check the SMPS voltage
2.Check the loose connection in monitor signal cable and power cable
3.Check the RAM
4.Check the processor,motherboard and VGA card


NO DISPLAY BUT LONG BEEP IS OCCURED IN THE SYSTEM?

If there is no display and long beep sound occurs then the answer is simple just
1.Check the RAM,RAM slot and replace the RAM. 


NO DISPLAY BUT ONE LONG BEEP AND THREE SHORT BEEP?

This is different from the previous .This contains different solution too
1.VGA card loose connection problem
2.Check and Replace the VGA card


EXTENDED MODEM IS NOT WORKING?

Modem always connect us to the world called internet,if it has a problem then the man will really become mad.To avoid problem on modem.
1.Check the CMOS setup and enable the modem part
2.Check the interface cable
3.Check the modem adapter
4.Reinstall the modem driver software


KEYBOARD PROBLEM?

To access the computer without a keyboard is not much easy.To avoid keyboard problems.
1.Check the keyboard interface cable property with the system and also check the connection.


We can solve all these problems only in desktop computers.Please avoid laptops because major or minor problems happens in laptop cannot be get solved easily as desktop computers.so just say no to laptops

Maximum problems are happening because of viruses,pirated version of operating systems and high voltage power supply so try to avoid those stuffs.Clean your RAM in regular interval of time,this all makes your system healthier

**** Now its time to say good bye to all your computer problems.****

Rubik's cube and the trick to arrange it....

The Rubik’s Cube was invented in 1974 by a Hungarian Sculptor and Professor of Architecture, Erno Rubik.

Of course, many kids could probably solve it in 5 minutes or less, many of us are very eager to solve this.Over 350 Million Cubes have been sold worldwide since it was invented.

A 16-year-old took the top prize at the Rubik’s Cube world championship, solving the puzzle five times in an average of 12.46 seconds but the fastest single attempt was a cool 10.88 seconds, just off the world record of 9.86 seconds.More than 250 competitors from 33 countries took part in the event, the first to be held in Hungary began in 1982.


HOW TO SOLVE THIS RUBIK'S CUBE:


How to solve this rubik's cube? Here is the trick to solve this magic rubik's cube.There are 7 algorithms to solve this rubik's cube.Those algorithms are explained below in this video. 

The seven algorithms are

1.Fi U Li Ui 
2.Ri Di R D
3.U R Ui Ri Ui Fi U F
4.Ui Li U L U F Ui Fi
5.F R U Ri Ui Fi
6.R U Ri U R U U Ri
7.U R Ui Li U Ri Ui L

(f-forward,u-upward,d-downward,l-left,r-right,fi-forward invert,ui-up invert,di-down invert,li-left invert,ri-right invert)

Don't mug up the algorithms,just try to implement practically by viewing the above videos.Practice more times.Don't loose your patience because patience is the key for making this rubik's cube in correct order

Modu Phone

Modu,an Israeli company announcing its unique phone called Modu.The Modu phone is sized at a little smaller than an iPod Nano and weighs at 42 grams only. Sports a small screen, Modu Phone packs only minimal keypad to navigate or dial numbers. Yeah, it look like Siemens Xelibri phone series with a bigger screen size.

For comfortable and fashion purpose, Modu comes with a jacket that will make it a full functional regular phone. Just pop the Modu phone in to its jacket and voila it become a regular phone with full keypad and has normal size.The jacket itself has no electronic component and will be changeable when available in the market with cheap price.

The Modu Phone boasts GPRS connectivity only for now, but Modu said that the 3G version is in the works. Modu phone is expected to be available in October in Italy, Russia and Israel with $280 price tag included a standard jacket.This also holds the guiness record.
