This started happening last night while i was playing Borderlands 2, it has happened at idle, playing just about any game in my library, during downloads and just browsing the web. I changed all of my accessible drivers, and it continued to happen, so i moved all of my personal files onto my external HDD. I re installed windows on my SSD (did not reformat) and reformatted my HDD. I re installed my drivers, re-enabled SLI and it ran fine for about an hour, just downloading WoW, and then happened again twice. let me know if there's any other information you could use, and how to obtain it. Please help!
