I have home ult. win 7,An ASUS CG-1330-7with,AMD T-1045 CPU,16gb ram,EVGA GTS 450 and a Samsung 120gb ssd 'C' drive. One day the display switched to windows basic and will not come out of it.If I click on an aero theme it will change the borders but not the screen.I can call up any theme I want and when I click settings it will revert to basic. I have gone into the various settings, tried both Auto and custom and they had no effect.I have also done a few clean installs with the restore disc.The machine did not come with restore disc's and I had to make my own and I wonder if they have become corupt?Also I have gone into the BIOS and turned off the internal graphics and set it to the PCI-XXX setting.
