So I just got my asus m5a99fx pro r.20 motherboard back from an RMA (something was wrong with the g diffuser, and the DRAM slots) and when I tried to boot up I got this error. I've never seen it before even prior to sending in my mobo, and all the info I found online said it's most likely a software issue but I just wanted to ask if my situation makes the possibility any different. Should I just go ahead with a win7 repair or god forbid a clean install if that doesn't work or is it more likely to be a hardware issue? My normal C: drive still shows up first in the bios (in case that's helpful.)
