Grimefighter locked mouse and keyboard

Just installed grimefighter all seemed fine and dandy… Aside from the fact on boot my mouse and keyboard no longer work. Can’t get the drivers reinstalled because I have no way of navigating to the files

How are the mouse and keyboard connected to the system ?

Via generic USB ports on the motherboard. I am running windows 7 using a i7 3.5 ghz prc , Asus Maximus vii hero 16 g ram and 2tb hd. I’m using a generic gaming keyboard and a g700 mouse. The USB ports are working because the mouse led light that show charging are working and when I reboot the pc the lights on the keyboard are on but once windows boots neither work

If the lights goes on it only means the mouse/keyboard is getting power.
It doesn’t mean there is any data transfer.

Try this:
Boot the system and wait e.g 15 minutes.
Disconnect the keyboard, wait 5 minutes.
Connect the keyboard to a other usb port.

The waiting times are just to make sure Windows can (or perhaps I would say should) notice something is changed and act accordingly.

The other usb port will tell (or at least should) tell Windows there is a “new” device attached and Window should install the drivers for it and configure them.

I can’t promise this will work, but let’s see what happens.
