Heating and humming computer In order to prevent the computer from overheating, it is necessary to regularly clean dust and dirt from it. Dust accumulated in the computer can cause an increase in heat, and if the temperature rises above 35 degrees, there is a risk that the computer will overheat and fail. It is possible to suspect that the ventilation of the computer is inefficient when: the computer is working loudly (rumbling); an increase in the temperature of the computer is felt, it becomes hot (felt to the touch); the computer turns off unexpectedly while working; programs, games crash while working; when turning on the computer, it stops booting, shows a black screen. We definitely do not recommend cleaning your computer yourself, as this is a process that should be performed by professionals. Computer dust cleaning process: the computer is completely disassembled (this must be done by an experienced craftsman); the computer cooler is carefully removed and disassembled; dust is carefully removed from the radiator, cooler, case, system board and other components; the cooler is lubricated, the thermal paste is replaced (it allows to reduce the heat of the processors). the computer is assembled; testing is done to show if the temperature is within normal limits; the computer is returned to the owner!
