Hello, my Windows PC is behaving strangely the past week. Usually when the login screen shows up, I just hit the Return key or click a mouse button and then enter the password to login to Windows 10. However, for the past week if I don't do so within a short period of time, pressing any key or mouse button does not allow me to enter the password. I have to force shut down Windows and reboot again. Anybody knows what is wrong and how do I fix this?
