I am experiencing something strange in one of my laptops that I haven't seen before. The laptop is an ASUS K52JC, has an Nvidia Geforce 310M. I have it setup as a dual boot with both windows 7 and windows 8.
It has worked fine for about 2 years. However, today windows suddenly crashed. After a reboot, the nvidia control panel complained that no nvidia graphics card was found. After running windows update, it now has a, fully functional, Intel HD graphics card. I first thought it was a software issue, but after rebooting to windows 7, exactly the same thing happened.
Is it possible that the graphics card downgrades itself to an intel HD graphics when the nvidia card breaks down? Or is this some a software/driver problem?
