Windows 10: Windows 10 boot and screen problems

My Windows 10 computer apparently tried to update overnight and for some reason was stopped before completing the update. When I came in the next morning I had only a black screen. I have searched for fixes and tried several of them, the last one being using a flash drive with the OSI on it to start over. My two monitors are active, but when I try to open a program (settings, display settings, calculator, etc.) the icon shows that the program is open and if I hover over it I can see a miniature version of it, but nothing appears above the task bar to allow me to actually use them. And, if I shut it down using the power button (the only way I have to do so since none of the other options work), Windows goes back to the black screen and doesn't finish loading. I'd appreciate advice about how to correct this. Thanks

Windows 10 upgrade problem, no input accepted

I really hate having to come here and ask for help, but I really am stumped. It hurts my geek pride. I have a PC with fairly modern hardware in it. It has a p8p67 pro in it. I have tried upgrading windows 10 on it twice now. Both times I have had the same result.

After windows finishes upgrading it goes to the log in/set up screen. I can't do anything. No keyboard or mouse input is accepted.

I will list some, or hopefully all, of the troubleshooting steps I have tried:

• Move keyboard and mouse to different USB ports.
• Try different keyboard or mouse.
• Restart computer, repeatedly.
• Google for related issues.
• Update Bios, because why not.
• Create boot media and revert to windows 7.

The windows 10 system restore boot media works fine with keyboard and mouse. All USB ports work in windows 7. I don't know what is wrong. I suspect that windows 10 is lacking a driver of some sort, but since the computer accepts no input I have no way of checking for which driver let alone installing it.

Please help me figure this out. If I have to revert back to windows 7 again, I am not going to get it upgraded to windows 10. Thank you in advanced.

i've seen this when the stock USB drivers went kaput. Only ever seen it once - i used a PCI USB 2.0 card and connected the mouse and keyboard to that, and manually updated the USB 2/USB 3 drivers.

 

windows 10 boot problems

I had windows 10 installed on my old laptop, I also had a boot problem, but my HDD just stopped spinning and I was unable to load windows.
It still had the Asus factory recovery partition which I used to reinstall windows 7.
I found out that my HDD was fine in windows 7, nothing wrong with it, staying with windows 7 SP1 on this laptop and I stay with windows 8.1 on my main laptop.
No windows 10 for me!
