Need Drivers to Install 64bit Vista

So like an idiot I cleared my 32 bit instillation without making sure I had the right drivers prepared before hand, and now I don't know where to look or where to go for the right drivers to install 64bit.

My problem, put simply, is that I need the drivers neccessary to install 64 bit vista on my computer and I have no idea where to find them.

I have and Intel Core Duo 2 processor and an MSI P6N Diamond motherboard, but neither site has been much help to me in providing what I thought would be the right drivers.

Right now I am open to any suggestions or advice. Tell me what to do and I will do it.

 

Vista. I said it in the thread name and the post.
