Well I have contacted them and the card has been sent and returned by the warranty manufacturer.
Inno 3D has not asked anything about the motherboard but I have told them ad given them a DxDiag.
I recieved a reply from them a day ago saying:
1) If you have used a 4-pin to 6-pin and 8-pin power converter, make sure both 4-pin connectors is connected to the card firmly.
2) Restore motherboard BIOS default and update the latest BIOS if available
3) Change the following BIOS settings if available
Assign IRQ to VGA: Enable
PnP O/S Installed: Enable
VGA Pallet Snooping: Disable
PCI Bursting: Disable
PCI Latency Timer: 128
Peer Concurrency: Disable
Video BIOS Shadowing: Disable
Video RAM Cacheable: Disable
USWC: Disable/UC
Pipeline Cache Write: Disable
PCI 2.1 Compliance: Enable (Only needed when using PCI graphic cards)
Passive Release: Enable
Delayed Transaction: Enable
4) Reinstall the Windows OS and update the latest VGA driver form the URL below: http://www.nvidia.com/Download/index.aspx?lang=en-us
Before installing new drivers make sure you uninstall all NVIDIA display drivers from the Windows Control Panel. Browse to the Start Menu > Windows Control Panel > Add/Remove Programs and search for "NVIDIA Windows Display Drivers" or "NVIDIA Display Drivers" and select remove.
Finally, if it does not resolve the problem, test the card with another system if available.
I followed this but to no avail. Most of the settings they were asking me to change in the BIOS was not available and the computer came iinstalled with the OS so a reinstall is out of the question. I have the latest driver (as of 07 Jun 2009 - v185.85) but this has not helped in any way.
The power connector that I was asked to connect in the manula and in the e-mail is not available but I have recently found a cable which may be able to fix that problem using an old 3-pin connector which I do not use (the product can be found here -

though I'm not sure if it will do the trick , I will ask instore. Mabe this is the problem. Mabe it's (this is what I think) sucking the power out of the motherboard from the PCI-E slot an leaving too little power for the motherboard itself.
All going well , I should get a reply back tomorrow , then I'll give you some more info.
