OK, fixed it. For some reason the device was disabled in device manager....just enabled it and it's working now.
Thanks very much for your help c-attack...much appreciated.
Oh and by the way....I never had HWINFO64 monitor the H115i Pro as the prompt mentioned there may be issues if allowed to monitor it, it was always disabled, I was just mentioning the HWINFO64 could see the H115i Pro that's all.
Cheers and thanks again.
