When you use a PC, after a period of time, a year, two, someone like. You can observe a significant deterioration in performance, slow and unstable operation of applications, you have to resort to frequent reboots, reinstalling the OS, there may be spontaneous shutdowns. On the part of the system unit, there begins to emanate an outside noise, a periodic howl, a vibration. Anyway, in order to avoid the failure of the PC, it is necessary to diagnose the fault and eliminate its causes.
That's right, we are going to investigate possible causes of computer failure.
In the course of their work, some computer components produce a lot of heat, one of which is the processor. To combat excessive heating, it is necessary to install a cooling module - usually these elements are a radiator and a cooler. If the processor overheats, the system starts to work slowly (slows down), can spontaneously turn off. On the Internet, there are many free utilities that monitor the temperature of the processor and its case. The reasons for the processor overheating may be several:
Stopping the fan (cooler) due to motor failure or bearing wear
Dust clogging the cooling fins of the radiator, fan blades.
Loss of thermal paste properties, which is applied to increase the heat exchange between the heatsink and the processor.
Determine if the cooler works normally, you can often hear it by ear. A fan with old defective bearings starts to howl and vibrate. Solution, replacement of the cooler.
If the whole thing is in the dust, then it is enough to remove the radiator and fan, clean the cooler blades and the fins of the radiator from it with the pressure of compressed air, (of course, all work should be done with a completely de-energized system unit).
Lost the properties of thermal grease can be seen by removing the radiator, the normal paste has a viscous consistency, unusable usually dried, hardly scraped off the processor and the bottom of the radiator. Eliminated by replacement.
To be continued.
Remember about it, - Turning to professionals, you save your time, money and nerves.
