I have a Mad Dog Dominator Cd burner that I installed (on my PC with Windows XP). When I turn on my computer, it only recognizes that I have a cd-rom drive maybe one in every 20 times. During start-up, when I hear it spinning, I know it will be one of the times it's going to work. The burner works fine at these times until I have to shut my computer off for some reason. Please help! :giddy:
