Keyboard and mouse no working in startup windows

My computer power button is blinking amber.Monitor is black. I replaced a new power supply and it's work.

However, I found the keyboard and mouse is no working after Windows start. The keyboard and mouse can be use in bios.

I have tried the following way:

1. replace CMOS battery
2. unplug RAM and plug it again.
3. unplug power cable for a few minute
4. make sure USB CONTROLLER is enabled in bios
5. go safe mode (keyboard and mouse not working in safe mode)

but with no luck.

What is the other solution to fix keyboard and mouse not working in startup windows?

You can try to plug-off the devices and uninstall keyboard and mouse driver in Windows, then try to reboot and plug in both the devices. Windows should recognize them and it'll try reinstall drivers.
