I'm surprised as many people are having issues with it - I've got probably 100+ of them and haven't had a single issue so far. Does it beep when it boots? Prior to the bios being displayed, all of mine beep - so if you're not hearing that, it might not even be making it to the point that the video would be initialized. You might also try forcing it to beep - normally if you boot with the memory removed, that will cause a POST beep to help you identify the issue, no post beep, then the board is probably no good.
Must be a new batch having issues? I'm having the same problem black screen problem and it doesn't go to bios.
No beeps and I've tried two different power supplies (EVGA GQ 1000W). I'm only able to get the keyboard to flicker once psu is turned on.
I also purchased 3 boards with none of them able to post BIOS.
Serial Number 0493-0495 is my batch.
