You guys having problems are you doing a custom install with the driver and choosing clean install ?
Also do not install the nvidia experience as this seems to be the cause of the issues.
So we have...
It could be your PSU
It's down to AA, turn it off
It seems to be Nvidia Experience
Are you doing a clean install
Flash your Bios
Anything else people want to think that might be the cause?
The issue is, THE DRIVERS!
Anything PRE 320.x's are perfectly fine for most people
