Okay, I installed the apple drivers and in the ati driver that pops up when you start it said something about turning off tv output or something like that,
I was messing around with a brightnes slider and slided it so that I could not see the screen at all.

I tried to slide it back but lost where my cursor was.
Now when I boot up windows it is just the first windows XP loading then a black screen. I tried safemode menu but I could not see it(if I even booted into it)
anyone know how to reset my brightnes?
