After installing and testing different versions of AMD/Dell Video Drivers and Goodle Earth, the problem was finally located.  It is a compatibility issue of Windows 8.1 DirectX with Google Earth.  In the last test, I started Windows 8.1 via "Safe Mode" and then turned on GE (Version 7.1).  The GE started nicely and, also, recognized the HD display which was never happened with Windows 8 before.  I was able to change "Graphics Mode" in "Opinions" from "DirectX" to "OpenGL" and rebooted Windows 8.1 normally.  The GE runs well since.       Max
I have just upgraded my Dell Inspiron One 2330 (touch Screen with AMD HD7650A) from Windows 8 to Windows 8.1.  I've also downloaded from Dell Download Center and installed all new drivers for Windows 8.1.  However, for some reasons, Google Earth (7.1) crashes every time I try to open it.  A message pops out and says that DirectX is not working, then closes the program.  I have checked everything, including Directx, and found no faults on either software or hardware.  It seems that Google Earth has problems with the resolution of the display?  Should I reload Directx?  Can anyone give me a hand?   Many thanks in advance! Max
