The computer won t turn on. Come on, the computer won t turn on.

Problem analysis: There are two situations when the computer boots up the black screen: the display is not powered on (the power indicator is not on) or the display is powered on (the power indicator light is on) but there is no signal or the screen shows "no sighal", the former means that the circuit is not connected, or the power interface or power cord is in poor contact or damaged, and the latter is generally a loose or oxidized memory module and poor contact, or the display data cable is not in good contact, or the memory, graphics card, display or data cable is damaged.

Handling suggestions:1If the monitor is powered on but no signal is displayed, turn off (if the short press of the power switch is invalid, press and hold the switch until the power indicator goes out or directly unplug the power cord) Power off the case, replug and unplug the memory module, and wipe the gold finger with an eraser in one direction (the back of the thumb fingernail is also fine), if possible, it can also be installed in different memory slots, and then turned on after installation (before operation, you should also touch the wall with both hands to release your static electricity or wear anti-static gloves).

If you don't know how to operate, then it's simple: slap or kick the chassis once or twice (pay attention to the location: the front of the shell on the left and right sides of the chassis that has no interface at the back; Attention Tract:

Don't push too hard, and certainly don't be weak). The above may need to be repeated, and if it doesn't work, you need to replace the memory module. If you have more than two memory modules, you need to test them one by one.

2.If the above operations do not work, turn off the power and turn on the chassis, reinsert the graphics card, and plug in the data cable between the monitor and the graphics card. If it still doesn't work, consider that the cable or graphics card is damaged, then replace it with a new one.

3.If the monitor is not powered on (the indicator light is not on), check whether the power switch is turned on, then check the back of the monitor, plug the power cord connected to the monitor upwards (the power cord can be replaced if possible), and check whether the other end of the power cord is powered on to the outlet.

4.If the display can be displayed when connected to another monitor or the display of this machine is connected to another normal host and still cannot be displayed, it means that the monitor is damaged and needs professional repair.

Check the lower line, or your voltage is not very stable.

Can't get into Windows or Bois?

The memory card、Have you taken it out to wipe it?

In fact, there are many reasons why you can't turn on the machine.,Tong leak is because there is no code Zheng and the late wheel of the memory module.,To check one by one.,If these are no problems, you need to take it to the repair shop to check.。

In fact, there are many reasons why it can't be turned on, such as no power and memory sticks, which need to be checked one by one, if there are no problems, you need to take it to the repair shop to check.

1. First open the case of the computer (only desktop computers, please find a professional staff to disassemble and check the notebook).

2. After opening the computer case, first check whether the battery on the computer motherboard is still charged. If there is no electricity, then you need to replace the battery.

3. Then look at whether the computer hard disk is damaged, if it is damaged, it can be repaired, and if it can't, buy a new one.

4. Then check whether the memory module on the computer is loose, and if it is loose, you can plug it back in.

5. Blow the chassis with a tool to blow the ash, clean the equipment in the chassis a little, of course, it is best if you can also disassemble some of the things inside and dry them in the sun, remember that the time can not be too long.

6. If you still can't turn on the computer after trying the above methods, then you should consider changing to a motherboard.
