Try each solution and write in comment whichever works

If only keyboard not working at login screen hold SHIFT button for 10 seconds and see if it starts working.
Enter bios under USB configuration and disable usb2 legacy support. save settings and restart computer. if doesn’t work then revert back to original settings.
Start computer when windows starts booting, unplug it from power socket. do it 2 times and on next screen it will ask you repair windows and next continue to restore to previous dates.
Disconnect keyboard and mouse , boot windows without connecting them, once reached login screen. connect them back if it works.
Remove HDD from your problematic computer and attach with another computer and run CHKDSK on windows partition. once completed. put back HDD and let it boot. hopefully it will fix
