SOLVED Installer console setup freeze

[MCDecaux]

First off, apologies if this is already solved but I couldn't find any posts of this kind :(

This is my first time installing FreeNAS.
I burned the ISO to a USB stick (8GB) using Rufus and managed to boot from that.
However when entering the installer console setup, the whole thing freezes, not allowing me to even choose any options. Neither the mouse or keyboard works, and there are no error messages at all.
Tried running Rufus in both ISO and DD image mode, same thing happened both ways.
Also tried using USB 2.0 and 3.0 for booting with similar results.
Also maybe worth noting; when I tried to remove the keyboard, it started to overwrite the screen with messages regarding the peripheral removals (see image below), so it seems the system wasn't completely frozen, just the installer screen.

Specs:
Motherboard - Asus A68HM-PLUS AMD A68H FM2+ micro-ATX
Processor - AMD A6 6400K
RAM - DDR3 1600 Mhz 2x4 GB
Hard drives - 120GB SSD (intended boot) + 4x1TB HDD

FreeNAS version 9.10.2-U2

Honestly I've no idea how to approach this problem besides console commands. Any help would be appreciated!

Frozen at this screen; text appears when plugging / unplugging USB devices

Other forum users have reported issues with Rufus. Instead, use one of the tools mentioned in http://doc.freenas.org/9.10/install.html#preparing-the-media as they have been tested as working for FreeNAS.

No luck there either, unfortunately. Imagewriter produces the same problem, and Windows USB/DVD Download Tool doesn't accept the image at all (error: Selected file not a valid ISO file)
(According to a guide I found, the Windows tool needs Joliet and UDF file systems as well. So I tried cycling the image through IMGburn to create those as well, after which it was accepted but still failed to create a bootable USB)

Any other ideas? Starting to think maybe I should just try to hunt for a writable DVD and try that.

Try a different keyboard. Or set it to the basic mode. Corsair's keyboards can occasionally not work very well in basic environments.

What do you know, changing the keyboard actually worked! Thanks!
Never had any problems like that before, so didn't even think of it.

Happens every once in a while. My K90 keyboard got a firmware update that added a compatibility mode enabled with some arcane button combination because of that.
