I want to install a new system, but now the computer turns on with a black screen

Black screen, are you talking professionally? A black screen just doesn't light up, the screen doesn't respond, it's black, there's nothing. Is it a black screen as soon as it is turned on, or is it a black screen after one or several screens appear?

1.If the screen goes black as soon as you turn it on, check whether the plugs are plugged in: otherwise it is a hardware problem (very unlikely), unplug the memory and graphics card, clean up the dust, wipe the gold finger, and then plug it back in, if it still doesn't work, it is the motherboard or CPU, graphics card, memory, etc. are damaged, then there is no way!

2.If the screen is black after the screen appears, the system is not normal, try to change the version of the system, if it doesn't work, change a few more, if it doesn't work, it's a hard disk problem, it's your problem to repair or replace.

If it's not a black screen, then there are many problems, and there will be a lot to say, so I won't talk about it.

It is recommended to reinstall the system on the C disk.

Get in touch if you have any questions! It's better to be specific, hehe.

Excuse me, you don't have some professional knowledge, do you? If not, then it is recommended that you take it to repair, because there are many reasons for this situation, we can only give you some suggestions, if you try those suggestions and it still doesn't work, (and not on the spot, can not figure out the accurate situation, we can only rely on experience and imagination to say a few words), then there is nothing to do.

I think if you're not having trouble with the partition formatting-reinstalling system, it's most likely a hardware damage (not tested, not checked, so I don't know).

Is that okay?

You are not finished installing the system, you have to learn to make the system now, the easiest is to buy a system CD, directly reinstall the system, but before the installation you have to set the disc boot in the BIOS, there are several ways, such as using the USB disk to boot with your mobile hard disk in the ** system installation, but you have to make a boot USB disk,

Why does the computer screen go black after booting up, and how to solve it.

It is recommended to use a CD or U to start the installation. By the way, you didn't say anything that caused the black screen, it is recommended to scan the hard disk for bad sectors first, or clean up the oxide layer of the memory gold finger.

If the safe mode cannot be entered, the CD or USB flash drive boots and reinstalls the system.

Reinstall the system.

If you can install it on a USB flash drive, use a USB flash drive to start the installation, and if you can't, use a CD.

Before installation, it is recommended to format the C drive.

Try installing it again.
