Occurrence: Recently, the author in the use of computers, machinery frequent emergence of a blue warning window, and then it crashes.

Failure Analysis: As the warning says garbled, and just before the failure to install a software download from the Internet, suspected to be the software with virus, immediately delete the software installed and used KV3000, rising 2001, and other antivirus software The investigation, killing operation, no virus is found. Shutdown and restart, about five minutes after the re-emergence of the phenomenon, repeated many times remains the case. Carefully pondering, I feel the fault is not caused by a virus, because each time the plane reboot, at the beginning of the work normally, only a few minutes away Dead phenomenon, it seems some of the hardware and machinery, especially The temperature of the CPU, so a set of hardware failure.

Troubleshooting: shutdown, open the main chassis inspection, when the CPU with their hands to touch the heat of films, was very hot, which is obviously not normal, suspected to be a fan or CPU chip issues. Open the chassis covered in the case of activated machines and found that the CPU fan speed is very slow, the heat has lost its normal function.

Shutdown, the fan removed by hand Bodong fan Shanye, Shanye the rotating fan feel very flexible, so with small screwdriver inserted Shanye fans at the bottom of the slot, and forced upwards slowly pry, Shanye fans and the entire fan at separation, and then turn Shanye, Shanye fans see in the center of an arc with a few small magnet into the circular tube-shaped enclosure firmware, obviously this is the fan motor rotor, The stator is fixed Shanye together with a micro-winding, if the fan Shanye combined with the fan on, then the micro-winding is inserted to the internal rotor.

Further observed that, at the top of the shaft in the stator and rotor bearing phase grounding of the parts are dry stick some black oil sludge, used gauze were erased its clean, and then to the point where few drops of oil, and then fan Shanye and re-grouped at fans, at this time, a finger gently Bodong Shanye fans can easily turn. Will re-install fans to the CPU heat sink, electricity for 10 minutes and then touching the CPU heat sink, I feel the temperature only in-state heat, the cooling fan that function has been restored. Cover chassis, reboot and re-install the system, everything is normal, long continuous operation, the fault does not appear again.
