Tips for Your computer Maintenance

Tips for Your computer Maintenance

Here for our blog Readers. I am very eager to tell some tips for your computer maintenance. If you follow these Instructions your maintenance charge will be reduced.

        Dust is the first enemy of your computer

Clean the dusts with brush in your computer keyboard. Don’t Keep your computer nearby dust easily entering area. Keep your computer closed area. Some time keyboard keys will be struck by dusts. So Keep your Keyboard clean with small brushes after switch of the computer. If you clean when the computer is on, there is chance to press unnecessary keys. You may press delete key when cleaning when a file selecting. So there is chance for delete your necessary files. If you Know the computer parts fully you can open the CPU and clean without touching the inside parts of CPU (motherboard, RAM, DVD drives etc.). How you will clean the CPU without touching? You can use vacuum cleaner to remove the dust.





2.       Move your computer after shut down and switched off

Sometime you need to move your computer from one side to another. That time you should power off the computer, or otherwise the parts inside may move unknowingly. The parts may create short circuit when the parts move at the time of running (That time the circuits are closed by passing electrical power). There is chance to your computer parts burning when short circuit made.



3.      If computer not Started After Cleaned or moved

It many time happens after cleaning computer. There is chance to cannot power on the computer because of loose connection of components. That time you just turn it off, and slightly press the components where it was situated. You can open after checked that all the components are connected properly.
4.       
       CPU running but monitor not working

Sometime Monitor’s Power cable or Monitor’s signal cable which is bringing electric signals from CPU may not contact properly. So Just switch off the monitor and CPU. Now check the power and signal cable of monitor in both end. (Monitors signal cable end connected with CPU, Monitor’s Power cable end connected with Power socket).

5.       Burning smell coming in your CPU

Just turn it off! It may cause of SMPS capacitor had completed its lifetime. Don’t turn it on. Call nearest computer service technician to check that and they will change the SMPS. Don’t make it on because there is chance to again burning completely (There is not very big issue will happen. Smell and pollution will be created if you put it on.)

6.       Don’t switch off your computer without shutdown

            So many temporary files will be created when a computer operating system running. If your                           computer is turned off properly the operating system will close all the temporary files properly and it               will create the situation to next time computer starts. If you switch off the computer without shut                    down the temporary files may still there. It may cause problem next time your computer starts.
7.       
         Don’t handle your CPU, monitor and keyboard hardly


          There is chance to damage your hard disk if you put your CPU hardly. The Hard disk made by                     magnetic particles. If your hard disk vibrated more than those magnetic particles will be damaged.                You may lose the data completely. Monitors screen will be affected by vibration. So Keep handle                smoothly your computer.

Operating system

Operating system

Operating system is a software create by programmers to operate a computer. Computer is an electronics device. First when you pressing the power button in a computer the computer do self test (because to know themselves and for user that what are the components are attached with the processing unit). After completed self test it will check the disc's Boot sector which is mentioned to boot from (in  BIOS setup). The program which is stored in Master Boot record of a disc is Boot Loader. The boot loader contains 512 bytes executing machine code.
Then the boot loader loads another program named Kernel for users to handle all the input,output, storage,process devices to simplifying the usage of computer. after loading kernel the ordinary user can use the computer very easily.
Boot Loader + Kernel = Operating system 
(First this is enough for understand that what is Operating system. Later we will going to deeply in future about operating system making.)
First I want to tell about computer then only we can briefly understand that how to make operating system. because we should operate each and every components in ourselves.
The attractive word in all the world. Because this machine doing so many works taking less time long time before doing by man with more times. Even Accuracy and time consuming is one of the advantage in Computer. All the fields are affected today by computers. So Everyone need to Know about that miracle machine. Someone still don't know about computers. I am here to teach something about that Unknown peoples (Dummies in computers) who is fearing about that simplest thing as simple and very very simple.

Computer:

Named because of computing machine. At first, that machine was innovated for reason calculating (Computing).
After that it was coming to document preparation, databases maintenance, security of data, images manipulation, video editing and variety of uses.

Architecture of computer simply is

  1. Input (Keyboard, Mouse etc.,) Unit  - To give input from user
  2. Processing Unit (CPU) - To process and store datas and instructions.
  3. Output (Monitor, Printer) - To get output after Processing.
