It's happened, literally, four times now. Within the past three days, I've experienced random red screen's of death. Whether I'm watching a movie or just idle on my desktop and talking to friends on teamspeak, my screen will randomly and instantly turn RED! As a matter of fact, it just happened exactly one minute from this post. I just had to restart my computer manually. Any idea what's going on? This is the first time I have ever seen and experienced this, and it seems like it's going to be an on-going problem unless it's fixed. There has been some subtle changes in my system; replaced an AMD video card and now, currently using, an Nvidia card. I also installed an OEM copy of Windows 7 Professional 64-bit; the LEGIT copy. So, what's the hypothesis? EDIT: Other things are; my Asus GTX 670 DCU II is overclocked using Asus GPU Tweak, but not even by that much; only 100Mhz on both the GPU and Memory.
