Lenovo G31 Motherboard does not boot how to do

Lenovo G31 Motherboard does not boot the solution one:

Can be divided into three kinds of situations:

The first is power after the black screen, there is no self-test of the "lap" and self-test error of the bell, this situation shows that the motherboard system does not work, to check the power is normal, the CPU is loose. There is also a situation where the BIOS is broken. Fortunately, the cause of the failure is not much, through the elimination method, it is easy to distinguish.

The second is in the self-test when the bell, when the memory, video card, keyboard and other issues, the system will ring the alarm. Different bios, its bells are different in meaning, you can check the motherboard instructions.

The third is after the memory detection, may be the hard disk, optical drive, expansion card, etc., can be based on the information on the screen to check separately. Failure at startup is not necessarily the hardware, and sometimes moving the computer may appear to be unable to start. I often encountered such a thing, moving a computer, boot can not start, then you should think of the hardware loose, take apart the chassis, the graphics card, expansion cards and other hardware plugging, most of the case will be resolved. This is more likely to happen for a computer with a softer chassis. So be careful when you move your computer.

Secondly:

First check the hardware has no contact problems, with rubber rub gold finger contact part.

The most common scenario is memory and motherboard problems. Try removing all other hardware and plugging in the memory machine, listen to have no alarm sound, if there is any more alarm sound processing, if not, it should be memory or motherboard problems. Try again with the replacement method. It is only after several rounds of investigation that the problem is to be known.

Generally added memory can not open the machine because the power supply is not enough,

But you put the new, or can not open the machine, may have damaged the memory slot, or burned out a part of the motherboard, may be just,

But first I suggest you borrow a power to try (the power of the larger type), if not, you can tell the situation again

First unplug the memory and then turn the system on. Can hear the alarm sound means the motherboard and CPU are good, can not hear the alarm sound proof that the motherboard and CPU are not working properly. Then try a good power supply. If you still can't hear it, it's probably the motherboard problem!

Lenovo G31 Motherboard does not boot the solution two:

The first step: according to the specific situation analysis, if there is no power response, then to see whether the power supply, bad contact, hardware and other issues, go to the second step, if it is not into the system may be the operating system or software problems to the third step.

The second step: check whether the power problem, first of all to see whether the power supply is not plugged in or plug problems, if the battery, then plug in the power to try again. You can find a friend or go to a computer repair shop, a sales shop to find the same type of power supply try. After reseating the power supply, press the Power-on key again, if still can not open, that more press a meeting. If someone else's power can be turned on, that is the power supply problem, if the power supply is not a problem, it may be the reason for the hardware, go to the fifth step.

Step three: Enter the last correct configuration to adjust, the pilot press F8, enter the Advanced Options page, select "Last Known Good Configuration", and then enter. If you can access the system, it may be infected with the virus, hardware drivers and systems are incompatible, operating system, and other questions caused. After entering the system, run antivirus software, killing the virus, if there is a virus, anti-virus after the restart of the computer, if it is not normal, it may be caused by the device driver and the program is incompatible, remove the video card, Nic and other drivers, remove the driver after the first restart, if there is a problem, then go to the next step.

Step Fourth: Repair the installation or reinstall system, set the "optical drive as the first boot device" in the BIOS, insert the system disk, and press R to "repair the installation". If the fault is still, just enter the system at the beginning of the time, select the "one-click Gost Restore System" or use the system disk reload system.

Fifth step: To see if the hardware problem, open the notebook to see if there is a loose hardware, the general hardware is not plugged in good will have the alarm sound, the long sound is constantly ringing to indicate that the memory is not plugged, a long short memory or the motherboard has problems, a long two short display card error. If there is too much dust in the notebook, it's better to clean it up first. In addition to pay attention to whether the new with the hardware caused by change, if the hardware before the normal, after the change is not normal, then check whether the compatibility. If this is not yet started, it is best to send repair, the professional will check your hardware is a problem.
