Here's a screenshot of before the black screen and after.
Basically, I can be playing any game and have over 100 FPS and everything will be fine. Then, at some random time (could be 1 minute or 20 minutes in), my screen will go black for 3 seconds, and then when the picture returns, my FPS is between 15-20 for the rest of the game. Then, more and more black screens will appear more frequently until either my game crashes or I quit out of frustration.
If you look at the picture I linked, you can see that my GPU Memory Clock is very steady and almost maxed and then just drops from 1500 MHz to 162 MHz. After this my GPU Load almost maxes out. My theory is that because my memory clock MHz is so diminished, my GPU has to work extra hard to maintain the paltry FPS it now maintains. Sometimes after this happens at the bottom right I get a balloon popup that says "display driver nvidia windows kernel mode driver version 320.00 stopped responding and has successfully recovered."
Here is the page for my graphics card specs. Other than that I have an Asus P8Z77-V PRO LGA 1155 Z77 Motherboard, a Corsair CX750 ATX12V 80 Plus Bronze Power Supply, 16 GB Crucial RAM, and Windows 7 64-Bit Ultimate. I haven't overclocked anything and other than installing drivers for all my hardware, everything is factory settings.
I have tried changing "Power Management Mode" in "NVIDIA Control Panel" to "Prefer Maximum Performance", changing the game's graphics settings, turning V-Sync on and off, closing all non-system processes except the game, adding TDR to the registry, updating/rolling back graphics drivers, doing a RAM memtest (all RAM fine), checking temperatures (everything always cool), re-installing the game, installing latest updates from Windows Update, changing PCI Express to OFF in Control Panel's Power Options, disabling UAC and firewall, running as an Administrator account, disabling unneeded services and startup in msconfig, installing the latest version of DirectX and flash, changing the CPU affinity and process priority of the game, and much more.
I don't think my GPU is defective because none of this happens with 90% of the games I play (only HoN and LoL). The GPU is only a couple months old as well and this has been happening the entire time.
