2.Cleaning hardware or physical cleaning
In my opinion this is the first thing to do, because when our computer is exposed to a dusty area these begin to accumulate in our tower, and thus begins to affect our computer parts such as fans, which when dust is overfilled not reached the rotation speed (RPM) needed, this causes the CPU starts to increase its temperature. In the case of laptops not only that but also occurs affected the keyboard because it starts slowly greased without realizing until it needs a technician.
Therefore it is important to make a good preventive maintenance every certain period of time, depending on the level of exposure that has our team.
3.Clean your hard drive regularly.
With frequent use in our computer accumulate an amount of data or temporary files that cause this slowing go every day without realizing it, that's why every day we make estrous removing files , I advise use specialized tools as CCleaner, TuneUp or Puran utilities (on this last tool to optimize and talk to them on my site above technology and solutions).
