Basically, I've been having this issue for the last few weeks.
Starts with my screen going off (kind of like when you shut down the pc the screen will go in standby mode) then my screen reinitializes and my computer reacts really slow to everything I do.
Finding a solution to this proved difficult since the one solution said I needed to reinstall my drivers for my videocard (which I did, and didnt help) while the other solution said to modify the .sys file from system32\drivers and put in the .sys file from the Nvidia setup (also didnt help).
In logs however it says at first its nvlddmkm but few sec later it reports that my screen is the issue.
Stuff like that.
Specs of my Hardware
Intel i7 2600k (Non Clocked) 3.4 ghz
16GB Corsair Vengeance Ram
Nvidia Geforce 560Ti TX Hawk (MSI)
750W OCZ Power supply.
