I hate to rez this thread, but I just wanted to update that even after replacing the ram, I was still having BSOD's. I checked my PSU which was lower than I thought, at 430w, so I purchased a new Antec 650w PSU. This didn't fix the issue either, but it was still a needed upgrade, IMO.
I'm RMA'ing for a board replacement with ASUS, and I I'll update from there.
What really troubles me is when my whole computer crashes during memtest86+. I'm going to see if I can re-produce this on a by test basis. Like, if a specific test causes the issue.
@w7pro: I would love it if this were a software issue, but I can't for the life of me peg it down. I've tried several fresh installs, and written my drive to zeroes. At this point, I'm pretty sure it's hardware.
