These days we live in such times that living without knowing and using a computer is like something which we can’t afford to do. Computers have become a very important part of our lives. Using a computer is essential for work, keeping personal files and to communicate. If you use a computer daily for various purposes, you should also know how to fix minor problems. Always make a back up folder of whatever you have so that you don’t lose any information.
If the computer seems to have fluctuating power, check if all the wires are intact. Old switchboards should be replaced immediately. Clean out the computer from time to time and make sure you don’t drop anything on the keyboard and mouse. You should fragment your disk properly so that chances of crashing become less. Finally if nothing works, reboot your system.
