Yeah, doesn't seem like something for pleasure reading... As far as to what's going on right now, the CPU is now cozy in a stock Dell Optiplex 7040 and BSODs on startup shortly before it would reach the Windows log on screen (MACHINE_CHECK_EXCEPTION). This machine seems to be running Win 7, which I don't think should matter though. The BIOS detected the new CPU and reset its settings (original CPU is a 6700, now a 6700K, so should work just fine). I can't get into Windows, so it's not as easy to get any logs. Considering this is 100% separate hardware now and a different OS altogether and still blue screening I'm going to stick with my CPU died theory and I'll try for an RMA with Intel. I can't even run the Intel tool because I can't get into any OS with this CPU now, so that's not something I'll be able to get you. :| Any other thoughts before I go the RMA route?
