Reset/turn off voodoo(s)

[Ariqu]

I have 2 Voodoo2's in SLI and a Voodoo1 that the V2's pass through. I sometimes have glide programs crash on me and the video gets stuck - the Voodoo doesn't pass the video from my main video card through anymore. I can restart to fix this, but it's bothersome. Is there a command or program that can reset the Voodoos?

BTW, in case it matters, I'm running Windows XP.
