What is the reason why the computer can't be turned on? Please talk about it in detail by experienced experts. There is also the kind that generally likes problems! ! !

Your question is a bit general. When you say you can't boot, do you mean whether the monitor responds or doesn't respond after pressing the chassis power button?

Have a reaction:

1, the fan is running, the display screen is normal, but it can't get into the operating system, indicating that there should be no big problem with the power supply. Take a look at the tips of self-check, and then try to set the Bios again (if you don't understand, please find a master here to solve it, I can't help you)

2. If there is nothing wrong with the Bios, it is usually the operating system. It is estimated that reinstalling the system should be able to solve it.

No response:

1, check the power supply, wiring and socket (nonsense)

2. If the chassis power light is on, the machine cannot be turned on. Listen to the alarm sound of the chassis speaker. If there is an alarm, it is usually caused by loose boards. There are many kinds of alarms, and it is impossible to explain them one by one. Just clean up the memory and graphics card and plug it in tightly.

The last thing I want to see is hardware damage. If possible, you can use a test card to test it. If we can find machines with the same configuration, then replacing the hardware one by one will definitely solve the problem. If you can't do it again, you should ask a dealer or a professional for help.

In a word, your question is too general, and you haven't said the specific situation, so it's difficult to analyze. I can name 100 problems that caused this situation. The above are more common situations for your analysis! It's interesting to help you solve the problem in the middle of the night! I hope I can help you.
