Basically, i downloaded a gamecube adapter and accidently replaced my keyboard driver with the gamecube adapter driver.

I've factory reset my computer still no go.

I've uninstalled the driver and now no longer can find my keyboard driver, i've spent the past 4hours trying to figure how to fix this crap.

Any help would be really appreciated.

(keyboard powers on just fine and my mouse which is plugged thru the keyboard usb hole works also)

What keyboard do you have

Just redownload iCue from corsairs site and do all the firmware updates in settings

Did it didn't work.

what happens when you change the BIOS switch on the back of the keyboard? it goes like 1-4 and it might help. or you can try switching usb ports, other than that not sure, would need to contact corsair and they might have something to help reset it

Just format it.

Your bored part of windows from the sounds of it.
Cause a factory reset did nothing.
