Steps to make good maintenance
1. It is necessary to check the fans and the heatsinks, since the
dust can damage them. Use a blower or bellows to remove dust.
Remember that the fan may be rotating at a lower speed than
required, therefore, you must touch the heatsink with your hand
to know what temperature it has, if it is very hot, remove the fan,
clean it, and lubricate it. If this does not work, you should change
the fan. This is done both with the computer's fans and with the
amplifier's.
2. Check the processor heatsink by touching it in the base, if it is
too hot, it indicates that the processor may be damaged. If this
happens, consider changing the fan. Check in the Bios, in the
section of (hardware monitor), the revolutions per minute of the
fan, if the revolutions are below 3,000 RPM, proceed to change
it.
3. Perform a Scandisk and a Ccleaner to correct errors created by
power outages or incorrect shutdowns. In this step, Windows
registry errors and lost chains are corrected.
4. Clean the monitor, the dust sticks on the screen because the
monitor is charged with static and it attracts dust. Dust is the first
sign of future damage, not to mention that it makes your machine
look ugly.
