I have just upgraded from IE8 to IE9. When I try and open a web page all I can see is a blank page. If I mouse over the page I can see tooltips so it's almost like the text is white.
I had the same problem with the beta and had to uninstall. I need to test my web app runs OK under IE9 now though so need to get it working.
I am running on a Asus N61J laptop. It has 2 graphics cards - an on board intel and an nvidia geforce gt 325m. A light glows blue when running in power mode with the nvidia or white for the intel.
If I start up IE9 the light changes from blue to white. If I check the use software rendering option the light changes back to blue and the pages appear. I'm guessing IE 9 sees the nvidia, tries to do hardware rendering and the nvidia can't handle it.
