Jack159 I had the same thing, I plugged the power cord in anyway, and it didn't work. No Big deal, I didn't use the black and white one either. I remember finding out what it was to, but I forgot. I'll have to look into it.
I bought this same combo from the Sacramento, Fry's and it has faired well for me. I haven't had a single problem, except it takes a little while to shutdown or restart. My Cpu is running smoothly and the heat has stayed I believe decent without any extra thermal paste. I don't remember the temp. it's supposed to be, but I think 38 degrees Celsius is average. I had 3 other friends that bought the same combo @ the same time and they haven't had any problems either. So I say it's a decent board for those wondering, however we are just 4 instances. I've seen other threads with people that had a few problems, but it looks to be flashing the bios will solve the problems anyway.
