I build a new pc and I have been crashing to desktop from games. I will get 3-6 sec black screens on games also. I have run memtest86 and that came out with no errors. GPU 27-79 CPU (27-61) after in game for 15 minutes on High settings. I have made sure to update my drivers and bios so now I think it might be due to the fact that the card is overclocked? I read I could try turning the card down but I am not sure how to do that or if its a good option. I am just looking for help on how to address this issue so I know what I need to update/buy/configure. 
 
Thanks!

I installed oc scanner but not sure what test to run 

I have not overclocked anything myself

Thanks for the reply!
 
I did a clean install of the graphics drivers with driver cleaner pro 15 and so far what little I have been able to play has worked. 
I am using HDMI cable. I have updated the BIOS and drivers but I will double check them. 
 
 I have MSI Afterburner and I'll try that next if I still crash on games. I can turn it down by 105 MHz

I turned the core clock down as low as it would go and in game it would still flash black and crash me. I guess I am going to try re installing windows nothing I am trying is working. 
 

What is an RMA?
 

RMA means Return Merchandise Authorization, it's where you get the product replaced, if it's under warranty. If you could call EVGA Tech support at 888-881-EVGA (3842) or send an email to support@evga.com and give us the serial number of the card, we can check its warranty status and see what we can do to help.
