HOW TO CONFIGURE VIRTUAL MEMORY IN WINDOWS OPERATING SYSTEM?

 HOW TO CONFIGURE VIRTUAL MEMORY IN WINDOWS OPERATING SYSTEM?



VIRTUAL MEMORY IS A MEMORY MANAGEMENT CAPABILITY OF AN OPERAING SYSTEM THAT USES HARDWARE AND SOFTWARE TO ALLOW A COMPUTER TO COMPENSATE FOR PHYSICAL MEMORY SHORTAGES BY TEMPORARILY TRANSFERING DATA FROM RAM TO INACTIVE SPACE IN HARD DISK DRIVES TO FORM CONTIGOUS ADDRESESES THAT HOLD BOTH THE APPLICATION AND ITS DATA. 

NOW LET US SEE HOW TO CONFIGURE VIRTUAL MEMORY?

RIGHT CLICK ON MY COMPUTER --> THIS PC -->PROPERTIES -->ADVANCE SYSTEM SETTING --> PERFORMANCE SETTING -->ADVANCED --> VIRTUAL MEMORY -->CHANGE --> UNCHECK AUTOMATICALLY MANAGE PAGING FILE SIZE FOR ALL DRIVES --> SELECT CUSTOM SIZE  --> TYPE PAGE FILE SIZE IN MEGA BYTES -->  CLICK ON SET ---> OK-->OK--> OK --> RESTART THE SYSTEM.

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.
