How to clean the dust after a long computer time?

After the computer is used for a long time, it is necessary not only to clean the dust, but also to replace the silicone grease and add lubricating oil to the cooling fan. If the system is turned on after power failure, and the date and time of the system are incorrect, and the past date and time are displayed, it is necessary to replace the CMOS battery (CR2032 button cell), and then enter the system after replacement, and set the date and time correctly.

Whether it is a desktop or a notebook, it is necessary to disassemble the machine to clean up the dust.

Desktop is easier to clean than notebook. If you take a desktop apart, it is mainly to clean the CPU radiator. After removing the CPU radiator, brush off the dust on the cooling fan and radiator with a brush, and also brush off the dust on the CPU socket and its surroundings (do not remove the CPU when brushing to avoid dust entering the CPU socket); If the cooling fan does not rotate smoothly by hand, add lubricating oil; Also wipe off the original silicone grease and replace it with new silicone grease (silicone grease coating is also particular, not the more the better).

Disassembling the notebook is more complicated. It's not as simple as upgrading memory and hard disk. Keyboards, screen cables and other items need to be removed. In the process of disassembly and installation, it is very likely that the cable will be torn and the wrong screw will be installed. Although there may be tutorials on disassembling such notebooks online, it is very likely that they will be done at first sight and scrapped as soon as they are done. If you really can't handle it, please ask a professional to handle it, or use a cooling bracket with a fan to help dissipate heat.
