Recently I installed W10 onto a separate hard-drive so that I could dualboot W7 and W10.


However once the installation finished and I went to load W7, I noticed that once I got onto the OS and the login screen, neither my keyboard nor mouse worked at all. The LEDs wouldn't change on the locks. After repeating this a few times, it seemed that once the BIOS was exited and the keyboard and mouse tried to restart, that they wouldn't activate like they should.

Weirdly if I mashed the mouse while it was dead, the LEDs would flicker. Taking the mouse out and plugging it back in would stop this, but it was reproducible once I restarted the computer.


I tried changing about the boot settings in the advanced BIOS menu including changing the initial drive that loaded and using safe mode.

Initially safe mode worked and I changed settings about in msconfig to see if it was a rogue service or startup program. On restart, the mouse and keyboard seemed to work fine once I re-enabled all the services.


Feeling like this wasn't the source of the problem, I loaded up W10 again, then back to W7. Surprise, the peripherals stopped working. This time even with safe-mode (and networking if it makes a difference) the mouse and keyboard didn't work.


Following another fiddle in the BIOS, but nothing I hadn't done before, W7 worked again in safe mode. This time I left all the services on, and it continued to work after restart.


Once more I loaded W10, then W7 in regular and safe mode. Both times the peripherals failed.

But once I entered the advanced BIOS again, W7 resumed normally. I have a feeling that this is what reset the problem.


Any clue to what is going on? Right now I can use my computer, but it seems touch and go.


If it makes a difference, my keyboard is a Corsair K70R and my mouse is a Corsair M95. The motherboard is a GIGABYTE Z87 series. This issue hasn't occured in W10 so far.
