Ok to start off where the problems occurred it all happened after I upgraded my gtx 760 2GB  to a gtx 1060 6GB. 

Specs:
core i5 4570 (stock cooler)
Lepa 500w PSU 24 pin 4pin 12v rail and 6+6+2 PCE Power connectors
EVGA GTX 1060 6GB Superclocked
MOBO: MSI H81M-E33
Graphics driver 372.90
Windows 8.1

The problem:
Its not with every game so far, but 2 have been giving me issues. Doom by Bethesda & Chivarly MW. When I try and play these games my screen will go black and my monitor will eventually say no signal. During this my computer stays on. Sometimes the GPU fan will run at maximum and sometimes it won't. I tried CTL+ALT+Delete, ALT TAB and the screen will not change. The sound will play for a few seconds as well. The only way out of this is to press the power or reset button on my computer. After that the PC boots up(Slower than normal) but everything seems fine.  This happens at random times. For chivalry I happened anywhere from the first 5 minutes of play to a couple hours, while doom took a few hours to have the same issue. 

What I tried and didn't work. 
Uninstalling and clean installing the graphics driver.
Reseating the card in the Motherboard
Trying a diffrent 6pin power connector. 
Running the fans at max to keep the Temps of the GPU down
Changing settings in the nividia control panel to debug mode. 
Tried using a DVI, HDMI and display port and all still crashed.

Notes:
My GTX 760 took 170w and my new card only needs 120w, so I don't know if the PSU is the problem, the computer also stays on during the crash. 
It is factory overclocked but I tried running it in debug mode and I still got the same crash.
I ran Furmark tests (1080p preset) and passed several times, MSI afterburner and CPU Z also show my temps never go above 80C for the GPU and 70 for the CPU.

Please can anyone help me?
