“Prevention is better than cure”. It is an old saying but it stands true in most of the situation in our life. It also stands true for your computers. Most of the time we hear people saying that their computer has crashed , or it is really running slow, but they never talk about the preventive measures they have taken to avoid such sluggish stage. A Computer is not a single unit (though it appears) but is a system which works when all the devices attached to it runs in accordance with each other and gives the best throughput. If one device goes slow then obviously everything will go slow. It can be seen as a tunnel where the entry point can be the hard drive from where the data is picked and the end point is the monitor, where the result gets displayed. Hidden inside the tunnel are the   Graphics controllers, Memory, Cache memory, addressing and spooling techniques, Processor, software and every other identity present in the computer system. Now anywhere inside the tunnel the traffic gets slowed then the entire queue gets slowed and we get delayed results. Example given above was quite hypothetical but it makes a good sense when we talk about computers performance.

You purchase a new computer with decent processing power, high capacity RAM, high-end graphics card, Large Hard drive. You are so happy and satisfied by the performance you get when it is young but one or two months down the line it starts getting slow. Let us understand why this happens and how can this be avoided by taking preventive measures.

Every thing that works or let other programs work exists in the Hard Drive. If your Hard Drive is over loaded then the speed of reading and writing will go slow, and thus it will not be able to cope up with the speeds of other devices like Processor and the RAM and will result in the entire system slowdown. Make a habit to run Disk Defragmenter and CheckDisk at least once in a month. You can even add these tasks in the Task Scheduler so that they run automatically even if you fail to remember. Path for Defragmenter is C:\Windows\System32\Defrag.exe and the path for CheckDisk is C:\Windows\ystem32\chkdsk.exe. use these executable files when you add the path in the Task Scheduler.

Another important measure is to keep on freeing space on the Hard Drive. This can easily be done by the disk cleaning utility available in Windows called as Disk Cleaner. Path of Disk Cleaner is C:\Windows\Syste32\cleanmgr.exe. This utility cleans all the junk and temporary files which get accumulated by time and this utility should be run at least once a week. Just like Defragmenter and CheckDisk this can also be scheduled in the Task Scheduler.

Over here I have not talked about increasing the performance of other devices like Processor and RAM because there is nothing you can do to improve them.  The Most you can do is to over-clock the processor but it is not advised at all. RAM, Processor etc are hardware devices and they work the way they are designed. There is no software means of improvising their performance and the only optimization we can do is of the hard drive and it should be done regularly
