Re: Gigabyte GA-Z77X-UD5H - Weird Power On Issue + DB Post Error...RMA?
Yes I loaded optimized default settings per your instructions. OS installed fine (Win7 Home Premium 64-bit). So now onto the power issue:
I tried a discrete graphics card again. In Slot 1 (closest to CPU), it does post now; I didn't realize at the time what was happening in bullet #2 above that Shutdown was putting it into a bad state. Slot 2 (middle), it posts to an "A6" state which is waiting for user input but the screen doesn't turn on. Slot 3 (farthest from CPU) does post and will load Windows. The power properties as described above remain the same with the graphics card in either slot 1 or 3.
I am 99% sure my power supply works as I used it to test my old ASUS Striker II board before I bought this board. Should I try a different power supply (have a Corsair 620 I think in my old computer)? Or any other things to try?
Thanks for your help so far!

- Restart from Windows or the motherboard directly works fine.
- Shutdown from Windows doesn't turn off the motherboard: LED is off, CPU fan is on, BIOS light blinking between main and backup. If I try to restart from this state, it will not post with a "db" error ("flash update is failed"). Long clearing of cmos, going into bios, and loading optimized defaults makes it stable again until shutdown again.
- Sleep puts the system in a similar state to Shutdown (fan on, LED off, bios lights blinking), but it does appear to recover from sleep strangely enough back into Windows.
