Screen goes black if the power cord is connected

Hi Tony,

As the screen goes black I suggest you to refer the Microsoft article on
Troubleshoot black screen problems and check if it helps.

Troubleshooting black or blank screens in Windows - Microsoft Support

I also see that you are facing issues with the keyboard this might be due to the corruption of keyboard drivers. I suggest you to run the
hardware and devices troubleshooter and check if it helps.

Follow the below steps for the same.

Windows 10 has a built-in troubleshooter to check and fix issues with hardware and devices. I would suggest you to run this troubleshooter. Refer these steps:

• Press Windows key + X, select Control panel.
• Change the view by option on the top right to Large icons.
• Click on troubleshooting and click on the view all option on the left panel.
• Run the Hardware and devices troubleshooter.
• Restart your computer and check if the issue is resolved.

Hope this information is helpful. Please get back to us with the information required, if you need further assistance, we’ll be glad to assist you.

 

Black screen when powering on PC. Fixed by removing power plug, plugging back

Potential causes of a black screen:

1. Installation in progress
   
   How to fix:
   
   
2. Loose Connections and/or Driver issues
   To Fix:
   
   
   
   • Check to see if your display is connected properly to your computer and to power.
     
   • If possible, change the video port (e.g from VGA to HDMI). There may be a driver that needs to be updated or reinstalled.
     
   • Disable the discrete graphics card, switching to the integrated one -- this'll tell you if it's your graphics card or the drivers used for it. You can uninstall and reinstall the drivers to see if that helps. If not, I would check to make sure everything is connected to your discrete graphics card properly -- (This is just the first video I found, but there are plently more if you need them.)
     
   • Try a different monitor and/or cables -- yours could be dying, have a bad connector, etc.
     
   
   
3. Something connected to the computer is causing problems
   
   Disconnect everything you can so you're only left with the essentials -- i.e. tower, keyboard, mouse, monitor -- restart, then slowly reconnect things one at a time until you find the one causing the problem. Check the drivers for the device, update (and/or reinstall), and restart. If it's still a problem, you'll need to troubleshoot with the product's support center.
   
4. Other (more complicated or obscure reasons)
   
   To Fix:
   
   • Reboot into Safe Mode
     
     Use the troubleshooting tools in the advanced startup menu to try to track down the problem
     
   • Backup your computer and do a clean reinstall. (It's far from ideal, but it can fix errors from a corrupt OS; and I have found this has worked for me before when Microsoft Support couldn't figure out what was wrong.) You can migrate over your files, settings, etc. if this solves the problem.
     
   • Check if the GPU is referenced properly in BIOS. Someone else had this problem.
     
   • Try Rolling back the Integrated Graphics Driver
