Get the latest Vista 32-bits/64-bits drivers from your manufacturer(s) and install them under Vista compatibility mode and as an administrator. Right mouse click on the executable -> Properties -> Compatibility (tab) -> Check both 'Run this program in compatibility mode for: Windows Vista' and 'Run this program as an administrator'.
