I have been gaming on a samsung monitor for over a year now with no problems. I just recently got a new monitor: BenQ XL2430T and now my pc will crash after 5-15 minutes of use. I'm not sure what the issue is. I have switched back to my old monitor and it works perfectly fine. Problems only arise when i use my new one. My old monitor used hdmi. I use a dvi dual link on my new one.
