Hi everyone, I'm having a horrible problem with Vista x64; it will keep locking up randomly and I have to manually restart it to make it functional again. I've discovered that the northbridge driver will not install. When I install it using the most recent ATI driver installer from the motherboard's page, it will tell me it's successfully installed. However, when I restart the computer and run the installer again it tells me that the northbridge driver is not installed. Is there any way to get it to install correctly? I'm thinking this might be the source of the problem I am having b/c I've checked all of my hardware, installed the latest drivers, and installed the newest bios.
