I upgraded my computer to Windows Vista and was changing some graphic settings. Something like system to automatic. Now when I turn on my computer I see the Acer empowering people. Then I see the progress bar with the text microsoft Corp. Then all black! I hear the startup sound and I can still log in. The system run fine JUST NO GRAPHICS!!!! PLEASE HELP!!!!!!! I have a Acer Aspire One. And the Erecovery will not boot.
