gtx580 crash?

Hello All!

I have a funny issue that I have only ever had with Battlefield 4 & Just Cause 2. After around 5-10 minutes of play the monitors connected to the 580 will go black, the fans on my 580 go to 100% and then after around 10 seconds windows crashes. To get my GTX580 detected I have to hard reset. 

PSU is a Corsair 1050   (was running SLI, No Longer am)

GPU is a GTX580

 

Any suggestions would be appreciated. 

Had the same problem with the same GPU, but my PSU was crap, so i changed and never crashed again.
