When my computer turns on the keyboard lights up to show that it has power; the mouse doesn't. However when I try to enter the bios using the delete key it won't work. It then goes to the windows login screen and the keyboard won't type and the mouse won't light up or work. I have reset the bios by removing the cmos battery and putting it back in. When I do this a screen comes up asking me to hit f1 or f2, but the keyboard still won't work. The keyboard I am using is the corsair strafe and I have also tried the corsair k40 rgb which doesn't get power at all. I have tried all USB ports and non of them have worked. I reset the Bios as I had changed a setting in the USB options and this is when my keyboard stopped working.
