I updated my GTX 280 video driver to the latest from NVidia (185.85) and I've gotten all kinds of error messages about missing files.
I rebooted into safe mode again and ran Driver Sweeper (the way I did originally as well), rebooted, installed 185.85 again, rebooted, waited several minutes and rebooted again.
It seems to be fine, no more error messages. However, I no longer have NVidia Control panel when I right click the desktop. When I open it inside the control panel, it's not the same. I used to have 3D objects and the ability to see multiple monitors etc. That's all gone. It's now just system performance and tools, etc.
Also, I thought NHancer would need to be set again. However, it still has my Nick settings as far as I can tell. Is there another driver recommended other than 185.85? How do I get my control panel back?
