I recently built a new system with a Gigabyte GA-MA770-UD3 motherboard and the northbridge filter driver will not install with the ATI installer. I've tried it several times and I have used the custom option. The system reboots, I run the installer again, and it tells me the northbridge driver is not installed. I'm having a horrible problem with my new Vista x64 machine where it will keep locking up, particularly in a game; I have to manually restart to get the computer running again. I've scanned the memory with memtest and Window memory diagnostic and they found 0 errors. I'm positive it's not my hard drive. That leaves the motherboard or a software issue as the culprit. I'm thinking the NB driver might be the solution, so could someone tell me how in the world I'm supposed to install it?

Welcome to the forum!

Please list your system components, like your mobo, memory, CPU, PSU, etc.

That's odd that it isn't installing, have you disabled UAC and try right clicking on the .exe and run as an administrator.

Don't worry. Although it shows it's not installed in ATI installer manager, it actually already add a new driver in your system. You can check it out over here:
Control Panel > Device Manager > System devices

You will see a new item name under "AMD PCIExpress (3GIO) Filetr Driver"
