I don't see where you followed a single step I gave you.
The steps I gave you said to uninstall the CCC bloatware which is not needed unless you overclock, and can cause problems. Be sure to remove it from msconfig>Startup and msconfig>Services (after Hiding All MS Services) before uninstalling in Control Panel>Programs and Features.
If your Display isn't satisfactory or you still have Standard VGA graphics then import the display driver from the Support Downloads webpage for your display device.
