I built my setup yesterday, and after the same issues, I fixed the issues, and played wow/use computer for about 12 hours. However, this morning I wake up and I'm not getting a display again with the errors below.
Tried reseating the graphics card, RAM, CPU, taking out the Lithium battery, resetting the CMOS, changing the RAM to different slot, checking all power cables (fans are spinning on gfx card)but no luck.
I had this problem yesterday but thought I fixed it when I resat the Graphics card! Used the computer for twelve hours last night and it worked fine until I shut down, and it didn't turn off, the screen just went off!
I get from the Dr Debug (Motherboard info mod)
0xD6 No Console Output Devices are found
0xD7 No Console Input Devices are found
I've RMA'd the motherboard last year, as I couldn't get power to it, they sent it back saying it was all working fine and updated it to be compatible with the new generation chips.
Here's my setup, all parts are 1 day old apart from the motherboard and Blueray:
