Computer boot motherboard does not power the solution

If it is a notebook, the motherboard does not have the power of the best timely repair. If you are assembling the machine, then the motherboard does not have power can be opened on their own chassis inspection. If the motherboard fails to form a circuit, then the power supply voltage is in vain. So careful examination, in the case of ensuring that the hardware is no problem, this kind of problem is easy to exclude OH.

1, testing soft problems

Of course, if the power light, then the power is connected, is not a monitor or system problems, you need to properly troubleshoot, with Safe Mode or System Restore method to try.

2, monitor

Of course, the monitor is the main problem, check the display wiring, if the light is not bright, it is possible that wiring has problems, Jack or loose will lead to such problems occur.

3, Power cord

Check the board switch, the voltage and the power cord is plugged in, in addition, checking the power cord and chassis connected to the place is not a problem, because there may be no power directly caused.

4. Power switch

If you are saving the machine, then the power switch is a need to check the part. Some power supply welding point instability or bad contact will directly lead to the voltage is not enough, sometimes without and cause unable to boot.

5. Power supply

If you save the machine did not choose the right voltage power, then the computer running is probably unstable or often black screen panic, DIY computers generally need to identify each host or hardware needs of the voltage, so choose the right power is the key to avoid this problem.
