I've used my GV600-8 for a number of years in an A7N8X (NForce-2) MB without any problem. A lightning strike fried one port on the card, but it kept on ticking. The PC finally died two years after the lighting strike of unrelated causes. So I upgraded to an NForce4 MB (A8N SLI Premium), but now I'm getting the dreaded 'Can't find KeyPro' error. This was a fresh install of W2K so old drivers should not be an issue. I've been through the uninstall hoops I've seen posted and the drivers look fine. I'll likely try one more time, but I don't think that's the issue. I almost think the dongle might be the problem, but I can't imagine why. It was never an issue before.
I was thinking of upgrading to a 1240, but I don't think this will solve my issue with this board. Although I did not think the new boards had a dongle. I'd rather get the old card working before moving to a new card.
Will the card work in an Intel P35 MB, something like a Gigabyte P35-DS3R? I hate to upgrade again (I already had the NF4 MB), but it may be the only option.
