usb keyboard works briefly and then stops

$

Recently changed mobo and cpu (from asus board and amd phenom to a gigabyte H87-HD3 and an I5 4670) and used sysprep to preserve my windows 7 installation

had a few hiccup on the way but its all working now


except for my main keyboard a Tt Meka mechanical keyboard which when i plug it in works fine for about 20-30 seconds and then stops

it has power as the lights remain on and if i plug my mouse or other keyboard into the usb slots on the meka keyboard they both work. Also if I put caps locks on in the keyboard that does work (an old apple usb keyboard) the other keyboard turns on its own caps locks so it is clearly recieving both power and data and is sending it too.

it has no specific drivers associated with it and i've reinstalled the intel usb drivers from the mobo website.

windows continues to recognise the keyboard right down to its brand and version, it shows up on my device &printers panel, but it just wont work. Under Device manager it is only a HID keyboard and in the USB cntrollers drop down it has a usb 2.0 MTT hub as its controller I think (it stops recieving power if I uninstall this)

Any ideas?


So far I've tried all my usb ports both 2.0 and 3.0, i've uninstalled and reinstalled the usb 3.0 drivers from gigabyte website, connected the keyboard via a portable usb hub


it's getting frustrating

Quick warning: while my reinstall was successful there were 2 hiccups

1. my new mobo doesnt support IDE so my old dvd drive is no longer working and I am waiting for the delivery of anew one.

2. cause I am using hdmi on an old samsung hdtv and a fairly new radeon gfx card, I am unable to access the bios due to handshake error over resolution. If I need to access bios I need to swap gfx card to an old one I own to access it. Which I rather not do unless I am sure its an issue that needs a bios fix
