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:
- replace CMOS battery
- unplug RAM and plug it again.
- unplug power cable for a few minute
- make sure USB CONTROLLER is enabled in bios
- 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?
F12
or similar boot options screen), else it would be an option somewhere within the BIOS/UEFI settings.
