The computer can t turn on 100, why can t it turn on the computer?

Is it the meaning that the computer can't be turned on??

1 Short: The system starts normally. No need to explain! This is the majority of cases.

2 Short: General error, please go to CMOSThe setup and reset the incorrect options. It's as simple as reverting to the defaults, which works most of the time.

1 long and 1 short: There is an error with the RAM or motherboard. Try to change the memory, if it still doesn't work, you have to change the motherboard.

1 long and 2 short: errors in the monitor or graphics card. Unplug the monitor and graphics card, clean it up, and try it on the installation.

1 long and 3 short: The keyboard controller is wrong. Double-check the motherboard.

1 Long 9 Short: Motherboard FlashRAM or EPROM error, BIOS corruption. Try a different block of flashram.

Constant ringing (with long, intermittent sounds): The memory module is not plugged in tightly or damaged. If it still doesn't work, you can only replace a memory module.

Ringing: The power supply and monitor are not connected well to the graphics card. Check all the plugs.

Repeated, short ring: There is a problem with the power supply.

No sound and no display: There is a problem with the power supply. (It's just that it's not powered on, it's corona, or some parts of the motherboard are reimbursed.)

The meaning of the prompt is that the hard disk is read incorrectly.

Although this prompt, but this kind of prompt can only be used as a reference, in my experience, it is very likely that it is not a problem with the hard disk, the weather is cold, the computer often appears like the landlord such a problem, the suggestions are as follows:

1. Reseat the memory module; (Most likely a memory module problem) 2. Clean the dust of the computer case;

3. Reset the BIOS to the default settings.

If the above 3 steps are not good, it may really be that the hard disk has a bad sector, or other other hardware problems, and the landlord can't solve it himself, so it is recommended to send it for repair and after-sales.

A disk read error.

Try plugging the hard drive cable back in.

After the computer is disconnected. Turn it back on.

1.Replug and unplug the connection cable between the hard disk and the motherboard, if it doesn't work, try to change it, it's very cheap, and I'll get it for 3 yuan.

2.Clean up the dust inside the host and clean it up on the hard drive.

In this case, you first need to recall the last operation before the problem occurred, and try to enter the safe mode of the system by pressing the F8 button, and then reverse the operation (that is, if you installed a certain software before, then now you will uninstall it). According to your previous information, the system cannot be loaded due to the change of hardware information, so in line with the principle of moving from simple to complex, let's first recall what software or hardware was operated before to cause this problem. , what software has been installed or what equipment has been abnormal recently (discoloration, temperature, noise, abnormal function, etc.).

If these do not solve the problem, in order to save time and deal with it as soon as possible, I recommend reinstalling the system to eliminate the system factors. At this time, if the system cannot be solved after reinstalling the system, then it is determined that the fault is caused by the hardware, and at this time, after gradually finding the abnormal accessories by excluding the access of the main hardware, choose to remove or replace them.

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.

Press Del to enter the BIOS when you boot up, see if the time of the computer is right, if not, the battery may be out of power and the BIOS settings cannot be saved, you need to replace the motherboard battery, if so, please find the Advanced BIOS Features and find the First Boot Device (the first boot device) Change the value to HDD-0, then press F10, and select Y, press Enter, and restart the computer.
