do the USB 2 slots work? BIOS should work if you use the black slots.
What version of windows are you running? If 10, do you have the installer? Can get it here:
Win 10 media creation tool
If you have Win 10, F8 will not work at start up. That function is turned off in Win 10
Download that on another pc and make a installer
Now change boot order so USB or DVD are first, SSH or HDD second
you probably also need to do this as Z97 Pro will fight you to let you use USB
in the boot menu under advanced settings change the usb mode to full initialization then save and restart. this will enable all usb devices and it will boot from the usb automatically.
Now boot from installer, the mouse/kb should work in here
on second screen, choose repair this pc, not install
select troubleshoot
select advanced
select start up options
choose one of the 3 safe modes
PC will restart in safe mode, kb/mouse should still be wroking
right click start menu
select device manager from choices
find USB devices in the last choice - I was blind, I couldn't see it - which is Universal Serial Bus controllers
removing the asmedia driver should be all you need to do.
I have both those drivers installed, the intel and Asmedia one.
