video screen upside down

My son hit a combination of keys which cause the video
screen to turn upside down. Does anyone know this
shortcut combination to restore the screen to normal
viewing. (I fixed it with a system restore; but I'd like
to know the combination of keys to fix it next time it
happens.) Anybody got an idea?

Yea, Mine turned 90 degrees! How do you reset this? I will use system restore, (thanks for the idea) but I'd like to know the easier way to rotate the image

Windows Xp does not do this, it is the video software you have installed
that gives you this ability and you are the only one that knows what
software and video card you have installed. If you look in the lower right
hand corner down by the clock, their may be a Icon that you can click on to
run your special options of your video card. You could just turn it off.
