TROUBLE SHOOTING FOR NO DISPLAY IN PERSONAL COMPUTER.

 TROUBLESHOOTING FOR NO DISPLAY

FRIENDS TODAY I AM GOING TO TELL YOU ABOUT THE CORRECT STEPS TO BE TAKEN


IN ORDER TO REPAIR THE COMPUTER IF THERE IS NO DISPLAY.  MEANS THAT WHEN YOU START THE COMPUTER, THE CPU FAN AND SMPS FAN IS RUNNING ALL LED IS ON BUT THERE IS NO DISPLAY IN THE MONITOR.


STEP 1  START THE COMPUTER AFTER 30 SECONDS  PRESS NUMLOCK KEY COUPLE OF TIMES.

IF THE NUMLOCK LED IS GETTING ON AD OFF,  THEN THE PROBLEM IS WITH THE MONITOR.  IF THE NUMLOCK LED IS ON OR STEADY ON OR STEADY OFF THEN THE PROBLEM IS WITH THE CPU.


STEP2--> SUPPOSE THE PROBLEM IS WITH THE MONITOR 

1) CHECK THE AC WALL OUTLET (PLUG) AND POWER CODE WITH THE LINE TESTER OR MULTIMETER.  NOW CHECK THE POWER BUTTON IS ON AND THE BRIGHNESS EVEL OF THE MONITOR.  

2) IF THERE IS NO POWER  IN THE MONITOR  THEN THE POWER PANEL MIGHT BE FAULTY.  REPAIR THE MONITOR IF THE POWER LED IS ON, EJECT THE VGA CABLE  FROM THE CPU AND MESSAGE WILL APPEAR ON THE DISPLAY.    

3) IF IT DOES THEN THE VGA CABLE OR HDMI CABLE IS FAULTY.  REPLACE THE VGA AND HDMI CABLE.

4) IF THERE IS NO MESSAGE ON THE DISPLAY, THEN THE MONITOR IS FAULTY.  REPAIR OR REPLACE THE MONITOR.


STEP 3-->  SUPPOSE THE PROBLEM IS WITH CPU.  DURING TROUBLESHOOTING WITH THE CPU, IT IS RECOMMENDED TO USE A MOTHERBOARD, SPEAKER AND DEBUG CARD.  EJECT THE RAM CLEAN IT PROPERLY WITH THE RUBBER.  EJECT THE CMOS BATTERY CHECK THE VOLTAGE LEVEL.


CLEAR THE CMOS ATTACH THEM AGAINAND CHECK FOR DISPLAY.  IF STILL THE DISPLAY DOES NOT COME ATTACH A GOOD RAM.  STILL THE PROBLEM CONTIUOUS AND THE MOTHERBOARD SPEAKER IS GENERATING 3 BEEP CODES THEN RAM SLOT MIGHT BE FAULTY.


SUPPOSE RAM SECTION IS OK THEN YOU CAN USE THE DEBUG CARD TO FIND OUT  THE PROBLEM OR ATTACH  A VGA CARD  IF DISPLAY COMES THEN THE VGA PORT OF THE MOTHERBOARD IS FAULTY AN IF THE DISPLAY DOES NOT COME THEN THE VGA CONTROLLER MIGHT BHE FAULTY. IN BOTH CASES REPAIR THE MOTHERBOARD.

EXPANSION SLOTS IN MOTHERBOARD

EXPANSION SLOTS IN MOTHERBOARD  Friends today i am going to share my knowledge and understanding of the expansion slots. So lets begin with our topic. Expansion slots are used to provide additional properties for carrying the computation task such as additional video, audio and sound, advanced graphics and Ethernet.   So lets begin with our knowledge hunting. I will start by AGP expansion slots. AGP AGP stands for ACCELARATED GRAPHICS PORT.  AGP was introduced with high speed 3D graphics display in 1996.  It is used for older graphics card types which is discontinued by PCI EX16 graphics port in 2005.   These were kernel version of AGP most of the brand in 1.5 volt DC.  AGP 1x channel and 66MHZ clock speed resulting a data table of 266 MBPS.   AGP 2x, 4x ,8x specification multiply MHZ clock to produce increase throughput. AGP 8x produces effective clock frequency of 533 MHZ resulting a throughput of 2 GBPS (2133MHZ) resulting a throughput of over a 32 bit channel. PCI PCI  stands for P

PROCESSOR AND HYPER THREADING A SHORT SUMMARY

PROCESSOR AND HYPERTHREADING Friends in the last post i tried to say something about computer science and mathematics relationship.   Now i am going to say something about processor and hyperthreading.   So let’s get started. The Physical Component By Which A Computer Is Made Which We Can See, Touch And Feel Is Called Computer Hardware Example Ram, Motherboard. ·          INPUT DEVICE   : These hardware are used to input any data, instruction on command insidea computer device.   example keyboard mo9use scanner microphone, webcam etc ·          OUTPUT DEVICE :   these hardware are used to get any output from a computer system.   example: monitor, printer, speaker. ·          CENTRAL PROCESSIG UNIT (CPU) : This Device Proceses All Instruction Given By A User, And It Also Other Haqrdwqaar Peripherals Example   :Microprocessor ·          MOTHERBOARD: It is the main electric circuit board which is made by a pcb(printed circuit board).   It hods all hardware componen

CODES OF LANGUAGE IN COMPUTER SYSTEM. WHAT ARE THE OTHER CODES WHICH ARE USED IN COMPUTER SYSTEM?

  CODES OF LANGUAGE IN COMPUTER SYSTEM.   WHAT ARE THE OTHER CODES WHICH ARE USED IN COMPUTER SYSTEM?   There are many codes in computer system which may remain unnoticed by many computer geeks and nerds.   I also first didn’t see it but I am going to share it because these are important codes and used by many computer hardware developers, vendors and computer software developers.    They are mostly understood by ELECTRONICS AND ELECTRICAL ENGINEERING geeks or nerds.   They are as under : ·         ERROR DETECTION CODES ·         ALPHANUMERIC CODES ·          REFTLECTED CODES First we will discuss something about ERROR DETECTION CODES.                                                                                                              ERROR DETECTION CODES:   Binary information , be it pulse modulated signals or digital computer input or output, may be transmitted though some form of communication medium or electrical wires or radio waves.   Any external noi
