So I went to bed last night after shutting everything down just fine, there was nothing out of place at all and I had been using it all day.
I went to tun it on this morning and nothing. Not even an attempt at booting. I tied clearing CMOS, unplugging everything and re plugging, tried the power button on both the front IO and on the mobo. The only signs of life are 2 LEDs that occasionally blink. one is red and it says DB1 under it, right under the BIOS chip. The second is white and is the third LED in the VSM_LED trio.
My temps usually stay in the 30's, I built this PC in January and have never had an issue with it until now.
