My Aspire One(with 2GB ram) used to have Win 7 Starter onboard but last July a message from Microsoft asked whether I wanted to do a check of the machine for the feasibility of installing Win 10. I accepted it, the test results were the netbook was ok for installling Win 10 so I went ahead. Beside having to upgrade the Ethernet card driver, everything went swimmingly well and for 2 months I've been enjoying using it but two weeks ago all of a sudden Win 10 starts up but doesn't boot all the way to seeing the desktop, the screen remains blank with only a circle on screen that moves when I use the touchpad.
