try to completely reinstall the nvidia driver.

did that with DDU before i was installing in the new gpu ( gtx 960 )

Maybe you have driver conflict.Try to uninstall your current gpu drivers using display driver unistaller(ddu,search it on google) and then install the latests drivers.

Ignore my previous reply,can u use your 960 on another system?Mostly a bad psu makes restarts during gameplay,but its not really possible as 960 being less energy hungry than 660.

make sure u dont have virus to blame, so do make sure you've got up-to-date antivirus software, but because it tends to happen while you're playing a game, I'm going to guess it's one of two likely hardware problems: your power supply unit (PSU) isn't supplying enough juice or your CPU is overheating.

If the CPU gets too toasty, your PC will shut down to save itself. To help diagnose, I recommend downloading HWmonitor or Core Temp.

It's also possible that you have a failing PSU, You could attempt to diagnose it with a digital multimeter or power supply tester.
