toshiba satellite L510 troubleshooting die alone

Laptop often gets patients with symptoms, the laptop suddenly shutdown, restart after a few minutes turned on , the processor fan is not spinning fun or laptop suddenly hang .Many things can cause the occurrence of the above complaints . One reason is , the fan processors are not working normally, or even does not spin at all when the laptop is powered on.
This case occurred on Toshiba Satellite L510 , when turned on turns itself off after a while, bluescreen.

After checking the memory, hardrive and overall board components, it turned out everything was normal . 
As I observe more detail, it often stops spinning processor fan and mainboard be very hot conditions.

The first step, lift the mainboard position to make room removing the processor fan . Loose one by one socket that is connected between the upper casing with the mainboard. 
There we see there are three wires in red, black and yellow that connect the processor fan to the mainboard. 
Red wire connected to the positive voltage, ground the black wire and the yellow wire is the signal giver status on the mainboard of the fan rotation, how the speed of rotation. 
If the fan does not turn on, of course, hot on the heat sink will be excessive and the sensor on the mainboard will make protection so that the laptop will die suddenly or abruptly restart .To cope with the death of a fan processors , we can membaypass inflows into the processor fan by disconnecting the positive cable from mainbaoard by connecting the red wire to the positive positive 5 volt USB power, or connect directly to the red power cable that is connected to the USB. 
Up here, the fan will rotate and work perfectly. And finally, the laptop is initially often die suddenly, bluescreen, now back to normal .
