This is my first post here with hope that i'm conform with the rules here and you can understand my limited english
I have VBox installed on a Win 7 x64 Host and try to install Win 7 x64 as a Guest. When i'm activate 3D hardware accelleration, so the guest crashes or tells that accelleration is not available. When i'm run Windows Experience Index on guest, so it crashes without blue screen. The guest is fresh installed, no modifications of configuration. Only the VBox guest additions are installed, not more. When i'm disable 3D accelleration in VBox config, the guest is more stable but very slow UI.
The host machine:
- Intel Core i-7 4770K
- 16 GB DDR RAM
- no additional video card (only CPU)
- 1 GB shared RAM with GPU
For the virtual machine config have a look at attached file.
For further testing reasons i have imported an older virtual machine (also Win 7 x64) which working perfectly on other host machine. Windows starts normal to the logon/welcome screen and after logging in and switching to desktop, the screen begins to "flicker", not readable but you can see that windows works normal behind. If you know where the start button is and click on that, a white frame opens at the place where the startmenu is. The same at all other windows, only white frames, no content and permanently flickering.
Hope that you can help
