I have a Windows 7 32 bit. I have a graphics card updated about a year ago. I was playing a game in my PC. Suddenly, i pressed Windows button on the keyboard. My whole windows screen was shifted to left (half inches). the start button on the left is not visible and the left side is black. I don't have any shifting buttons on monitor nor anything like that. But, the BIOS screen works fine and the Safe Mode too. I tried to change resolutions of the PC but it, did't worked. I tried to rotate screen but nothing worked. Is there any calibration software to fix this? I tried Windows Restore Utility but it too did't worked. Thanks from advance.
