Everythings turned 90 degrees. hellp

Ok, just today I logged onto my computer and the screen was turned 90 degrees, still is >_<. The mouse is acting like its turned 90 degrees too. This is becoming a big problem and I would like some help as soon as possible @_@. If you need my system specs let me know and I'll post them on here. My neck hurts from this thing lol. Is it a virus or something wrong with my hardware? Help X_X

 

If you have an Nvidia video card, go into the Nvidia Control Panel->Display->Rotate Display->(rotate it back to where it should be) Im not sure how to do this on an ATI card but it should be similar

yay ^_^ its fixed! thanks for telling me that lol. But, why did it turn 90 degrees in the first place?

 

I really have no explanation why it would have done that in the first place. maybe a friend playing a prank? anyways, glad it got fixed. BTW, welcome to MG
