monitor went from horizontal to vertical

I have DELL 4600, with a 17inch flat panel monitor. I was on google earth when it just stop loading and everything froze. Upset by this I pressed several buttons at the same time and when this happen my tool bar went vertical and my computer shut off. I called my tech friend and he said to come here to find the answer on what to do. I went to properties from the desktop and every thing is running fine it says. Any suggestions, before I call Dell and be but on hold forever.

 

Am i understanding this correctly,
The Task Bar/Start menu Is Now Vertical on the side of screen???
Yes___
No____

 

why yes, yes it is.

 

Left Click in center of Bar And Drag It Down To Bottom Of Screen,
Then When It Is Back Down There,
Right Click On It And Check Lock The TaskBar...

 

Ok , I mean my whole screen , just not the tool bar. That is now Horizontal but evrything in the tool bar is vertical as well as my screen saver and this web page. I either need to turn my monitor or lay it down to read it.

 

errm check fiddle aroudn with the buttons on ur moniter. I can flip my image 90 degres i bet this is what happened to yours.

but how u descriped it it might be something software. like your videocard drivers had a hotkey to do this.. what is your video card? ATi? Nvidia? onboard?

 

That's the first thing I tried, I even hit the factory setting button, but it's still vertical

sorry, not sure what card I have .....starts looking

 

my guess then its a hotkey that put that function on.. like i said ATi? Nvidia?. Maybe toss them and email and ask them how to fix it

 

Right Clik on desktop,
Left clik on properties
Left click settings tab
Left clik advanced Button
Left clik on Video Card Tab (Your Card Shows Up Gforce 5200, 6800, etc)
On Left Pane That Opens,
Click NV Rotate And Change Perspective There.

 

Thank you so much, For Dell User's this is what you do.

Right click desktop
Left Click properties
Left click Tab Settings
Left click advance
then
left click on Intel(r) Extreme graphics
left click Graphics properties
click rotation
click ok when you select the right one.

Again that's what [v75th]CB said, but in different words.

Thanks again, now I don't need to turn my head to the side anymore.
I will pass this site on to anyone who else needs tech support, great site!
