Hi all, I have an ongoing problem with crashes when playing games. I get no BSOD, screen just goes blank and then loses signal, only option is hard reset. As there is no blue screen, it is difficult to determine what is causing this, I have listed some points below:

- Games that have caused crash are CS:GO, Black Mesa & Defense Grid! COD Black Ops however plays perfectly with no problems. All games are running on Steam.
- I have stress tested the CPU & GFX card and run memtest to see if any of these are faulty or overheating. These tests have not brought up any faults.
- As there is no BSOD I don't get normally get a Windows data dump file, although it did generate one once and I've attached this file
