I can't type anything on the Windows 7 login screen or move my mouse cursor. I just bought an Asrock b250m-hdv motherboard and an i5-7600k processor.
I am trying to boot Windows from an old harddrive. The keyboard and mouse work before the login screen and they work on other computers. I have tried booting it in safe mode and normally. Any bit of help is appreciated!
 
Solution
Read the info in the link about win7 with newer gen intel or amd MB. http://www.asrock.com/microsite/Win7Install/ May try that method to reinstall the win7 or use win10.
