What type of crashing is going on? Is it a black screen? BSOD? Screen freezing?
I was was having a problem where after installing newer NVIDIA drivers and Windows anniversary update, I started getting random black screens crashes forcing me to reboot. I could still hear my friends on teamspeak but no audio from game I was playing or YouTube video I was watching, which leads me to believe my video drivers are crashing. For days I couldn't figure out what it was.. I had a 980ti at the time and bought a 1080 out of spite to diagnose my problem (might keep it because I'm a sucker for fps >=) ) but resulted in the same crashes.
Ended up resetting my overclock on cpu and on my rams xmp profile. Played for 6 hours straight and not a single crash.. I reset my xmp profiles and everything is good so far.
My OC was stable before all this. I won't deny that it could be a dying cpu. But too many other people are having the same problem for me to conclude my diagnosis.
I started looking around NVIDIA forums and found a couple threads of people updating Windows and drivers resulting in driver crashes. There's a problem going around with the new Anniversary edition of Windows and NVIDIA drivers.
