Changing Display orientation WinXP laptop?

The display orientation on my win xp laptop changed to portrait somehow.Now it looks Like the Screen fell over on its side. I understand that this feature is useful for tablet pc users, but i have a regular laptop and its unusable with the screen on its side:)

Does anyone know how to change this setting back so I can have my screen upright again ? Any help appreciated.

click on an empty spot on your desktop. click on properties. click on the settings tab. click on advanced. having an nvidia video card, i click on nvidia and then nv rotate. check the box with landscape apply and ok. I don’t know if yours will be the same, but it a place to start
