The earliest computers were huge devices with huge transistor and cylinders. Efficient cooling systems occupied a lot of space. Technicians often faced problems when flies and insects landed on the cylinders and short circuited the system. Today, we can work on computers that occupy not more than half a table and can work without any worries of flies or mosquitoes damaging the system.
However, this does not mean that the system is perfect. You may, at some point of time or the other, find that certain simple commands that worked before do not work well.
Instead of fearing that something is seriously wrong, try the following solutions before taking any further action.
Restart the computer. This may sound unscientific but restarting the computer is very much like taking a nap so that you can recharge your batteries. Nobody knows why it works but simply rebooting the operating system can sort out many minor problems.
If this does not work, one should run an anti virus scan to check whether the computer is infected with the virus. If not, one should use the system restore option to restore the registry and essential files to the earlier date. An odd function or transaction carried out by a software application may have corrected the registry. Restoring information from the automated backup system should do the trick.
If nothing else works, one may have to go in for a complete reformat. Before doing so, it is important to check whether the problem is caused by a recently installed software application. If that is the cause, reinstalling the software application may solve the problem.
