Question that you guys maybe can help with

A buddy of mine just got a new mobo, Gigabyte 64-bit one.  He had to take back his agp card because this one only had pci-express.  

He gets the new pci-express card, sets everything up, powers the computer up, and gets no video output.  Can\'t even get to his bios.  Any idea why its not working?

Ok, now if he takes this back out is it working, does the OS load up at all with or without the PCI-express card? And does he have an on board video controller on it already? Sounds like an I/0 conflict but I\'m not too sure and there are a few other geeks in here that would know for sure.

Nevermind, we figured it out.

so what fixed it?

I had the same problem when I built my AMD64 system, my bios wouldn\'t recognize the newer 90-nm winchester cores.  It wouldn\'t even post.

I had to have a friend of mine flash an extra bios chip I had to the newer version and violia... it worked.

He didn\'t know that you couldn\'t use a 3 memory stick configuration.  Finally he just took out one of his sticks and it worked.
