our hp computer has been wipe clean when i turn on just black sceen what can i do
More information needed. Do you get the BIOS display when you first turn it on? Do any of the leds light? How was it wiped?
Wiped? Did you do the wiping? If all got formatted, I would reinstall your choice of operating system from a system disk and go from there. There is a good chance you may have a disk that came with. IF however you started the cpu up and its just black screen and you don't know anything about why that is the case, and you have checked the physical components and they are in great shape( for example the monitor cord isn't unplugged or loose, or eaten) You may have a malware. Have you tried cont alt del? or reboot in safe mode?
edit: took too long on my response the above beat me to it

Even if it has been "wipe clean", something should appear on the screen when you boot up.
