noob question so please be kind...

After installing my E8400 and doing some testing I did a clean install of my OS.
After Vista 32bit installed I loaded the drivers from the Maximus CD, after a quick 3dmark run I upgraded my Matrix Storage Manager driver from Intels site.
I now have version 7.8.0.1012 11/9/2007 installed and personally Its a pos.
I have small delays when reading HDD but there not all the time there intermitent, 3dmark is down a few hundred points, so my question is how can I revert to the driver on the cd and not do another clean install?
The folders on the disk are somewhat unclear and alittle adivice would be greatly appreciated.
