I have searched and googled this like mad and cannot find any answers or issues similar to what i'm having. (Maybe I just suck at googling)
For the last week i've been having a massive problem with my Nvidia Drivers.
Every time I boot my computer, it seems that the graphics drivers are either failing to start or just disappearing.
No errors show anywhere i've looked.
Firefox Crashed on startup, chrome will load, but will not open any pages.
Steam fails to start, as does Razer Synapse.(both of these are set to start on boot)
When I open the Nvidia Control Panel (which starts like normal) The Preview box is blank.
Hmm... strange. I would wonder about a virus. But first, make sure your system is clean of registry errors and resource hogging junk. Run CCleaner and do the clean and registry both. http://www.piriform.com/ccleaner
Then I'd uninstall the gfx driver again and run driver sweeper from safe mode. http://www.techspot.com/downloads/4266-driver-sweeper.h...
Have it remove any remnants of AMD, Nvidia, and ATI graphic driver files it finds. Re-boot and do the above CCleaner one more time, and then install the latest driver for your O/S and card. You may also want to go to windows system configuration/start up and uncheck any items you don't need. they all steal resources. For comparison, I have 6 checked.
Finally, run a FULL virus scan with a good virus pgm. Also, I like to keep Malwarebytes running to eliminate malware.
