I recently installed Windows 8.1 Pro. The only driver I installed was the chipset driver for my motherboard ASUS P8Z68-V PRO/GEN3.

When I start my PC, keyboard and mouse are responding in BIOS. But when Windows shows welcome screen, keyboard and mouse are not working. Shutdown + power on doesn't help. Pressing reset button DOES help. I have logitech wireless keyboard+mouse set.

It's very frustrating that I have to reset my PC every morning when I start it.

Anyone familiar with this behavior?

UPDATE:

  • I have Windows 8.1 driver from ASUS support page.
  • The same behavior exists even if I don't install any drivers after clean install.

I would remove the chipset and see if it helps. I am going to guess you install a version that does not support Windows 8.1 ASUS is slow in that regard even for its current flagship products. I have found that Windows 8.1 and Windows 8.0 drivers are not compatible with one another. –  Ramhound Oct 31 '13 at 10:58
    
Thanks for reply, on ASUS support page I found Windows 8.1 drivers for my motherboard, so I have a valid driver (I updated the question above). –  Darmak Oct 31 '13 at 11:12
    
Your keyboard and mouse PS2 or USB? –  Ramhound Oct 31 '13 at 11:59
    
USB. One wireless receiver for both mouse & keyboard. –  Darmak Oct 31 '13 at 13:08
    
Have you tried a different USB port? –  Ramhound Oct 31 '13 at 13:29

There seems to be issues with Windows 8.1 and ASUS motherboards. Links:

Unable to use USB ports since upgrading to Windows 8.1 Preview

I had a similar problem as the OP and updating the BIOS solved it for me.
