  1. Try all USB ports.

    I've tried all the usb ports; front panel usb3 and motherboard I/O panel both usb3 and usb2 and still no luck.
  3. So when you boot up into Windows 7, the mouse and keyboard works? Does the problem occur ONLY at log-in screen?

    The keyboard and mouse work in bios and on the screen where you select safe mode or boot windows normally etc. as soon as I hit the log in screen they both stop working
  5. Is the motherboard of the same model as the previous?
    After a motherboard change i always suggest a complete re-installation of the OS.

    What you can try doh is to boot your computer into safe mode seing if it works there.

    No, my previous board was an MSI z87-G45, the new one an ASUS Maximus impact, both are z87 chipsets though so I didn't expect too many problems.

    Even in safe mode the keyboard and mouse don't work. I've considered doing a reinstall but after reading around I think the OEM version of windows 7 I used can only be used for one motherboard, is this true?

    The license is bound to the computer in legal terms, it is not controlled by hardware, the only problem it can give you is when you´re trying to activate it. But a simple phonecall to microsoft saying that you changed MB should probobly solve that.
    Even if this was the problem your keyboard and mouse would still be working but it would say "Your liecense is not valid.."

    Í´d go for a full reinstall to skip further issues.

    That seems to have done the job, all is working well so far, thanks a lot!
  9. Hi,

    I just changed my MB and have the same problem. Tried to reinstall Windows but I am unable to pass the first install screen, because the mouse and keyboard are not working. They have no power at this point, even though they work just fine when entering bios.

    Any ideas?

    Thanks!
