So as many of you are familiar with a basic gpu overclock you load up a benchmarker (I was using the Heaven benchmark) and you have MSI after burner next to it while it's running and you change the settings as you go (yes there are multiple ways to OC) but coming across this I had experienced about two freezes or so and then I kept cranking up the core voltage by +10 mV as needed and +10 MHz to my core clock. Now mind you that my memory was stable at 7800 MHz and that's what I was running on. So my question is that after i had reached a certain point in ramping up the "horsepower" of my card it froze again.. So I reboot and on the bottom right it gave me a little bubble cloud pop up from the bottom right of the screen but it said something about drivers I believe (I glanced at it) and ever since then no matter how many times I adjust the speeds and press apply my gpu has been GLUED at the stock speeds and will not change . I checked the drivers as of 01/04/2016 and its up to date via GeForce experience but I'm not sure what happened so any help would be greatly appreciated
