The desktop computer won t turn on!! Urgent

Well, the system is broken, reinstall it.

It's not that you can't read the disk (unless your optical drive is also broken).

You should set it up to boot the cdrom first and you can read the disk.

In general, we set the first boot of the hard drive, so you have to change it.

When you turn it on, press the delete button continuously to enter the settings page, how to set it up, look at the motherboard manual when you buy the computer, which has taught you which is the setting, you should be able to understand.

Apparently the system is malfunctioning, you can just reinstall the system. How can you not read the disk? You set the disk to be scanned at boot to the *** optical drive, so that you can reinstall the system.

I don't know if you can use dos, but if you know dos, then you can do some things under dos, such as giving it a copy to overwrite the original thing.

Pay attention to :

1. Please check the power supply and data cable of the hard disk and the optical drive, if the power interface or data cable interface of the hard disk or optical drive is not in good contact, it will not enter the system, and even the optical drive is shielded! Replace the power socket or data cable.

2. This will happen if you are infected with a virus! Reinstall the system.

3. The host motherboard will also be damaged if there is too much static electricity on the motherboard. To discharge.

4. If there is static electricity in the memory, the kind of file you said will be damaged! To discharge.

Listen to your story, this is because your computer memory and the gold finger of the graphics card are oxidized, although you also deal with the memory, but you don't deal with the graphics card, and this memory you had better change a slot, your problem will be solved, and you can light up the computer.

Solution: Solution: You can first power off, open the compartment, dial out the memory, use the eraser against the part of the gold finger (that is, where there is a copper sheet,) back and forth a few times, and then change a memory slot to insert it back, it's OK, if there is a separate graphics card, you can also use the same method to deal with the graphics card, just don't change the slot, it's OK, if possible, it's best to put the computer's motherboard button battery down, that is to say, remove the button battery for a minute, and then install it back, This saves you from doing the above and makes your computer more stable. Then set the optical drive or hard disk as the startup item, turn off the software drive, it's OK, I hope it can help you, I wish you success and happiness.

1. The display data cable and the host are not connected.

2. Wipe and install the memory module again.

I've been in this situation.

I don't know if it moved to the color of your monitor, those settings,I once accidentally moved to the lowest brightness,The screen is black,And you check the cable connection!

The monitor data cable and the host unit are not connected properly?

Take the memory module out and wipe it.

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.
