OK, now I had DC running in the background (alt-tab to Firefox), with a few websites open (Divinity: OS, DC, and SC), along with Star Citizen Chat Roll. I closed most screens, and had only SC Chatroll open (with DC still running in the background). I had just selected a website Sixsense (.com?)... and my monitors started to go crazy (blacking on and off slowly). Then I get a blue screen of death and it dumped to memory.

I was able to restart my computer, but I'm extremely worried that it could happen again if I run DC (in the background or not). I don't want to destroy my video card.
