Deep Singh writes in with a troubleshooting question.
Q. My desktop display is upside down, i.e. everything is upside down
A. Try pressing ctrl and alt together then either the up, down, right or left arrow key to rotate the screen. You can also check your display properties by right clicking on the desktop and selecting properties and see if there is a setting in there maybe under Advanced to rotate the screen back to right side up or to disable rotation. If that does not work you can remove the video card from device manager then reboot and let it find it again to see if that fixes the problem.
