I am hoping someone might be able to give me some guidance on how to fix this problem/where to get started.

I have the following motherboard.  http://www.asus.co.nz/products.aspx?l1=3&l2=11&l3=195&l4=0&model=538&modelmenu=2

And I have installed a video card and a HVR 300 tuner card.  I also have a PVR 150 card that I want to install, but I am having some problems.

When I install the PVR 150MCE into my free PCI slot and restart the computer, the network card/on board does not work, but it works fine when the PVR 150mce in uninstalled.  I have done research and it sounds like I have a conflict with the Network card alloacted to one of the PCI's.  I don't (I think - will double check agian) any free PCI slots, so I need to find a way to reslove the conflict.  Some of the research suggests an IRQ allocation problem?

Any suggestions would be appreciated.

Cheers
