New GA-990FXA-UD3 Rev 3 MB will not power on. Pressing the power button yields a brifi flash of the power indicators, fan spin then off. This is in every configuration.
Specs:
AMD FX-6300 CPU with stock cooler
RAM Kingston Hyper X DDR3-1600 (2x4GB)
RADEON hd6870 gpu
PSU: 730w
All power connections have been verified. Testing included placing the MB on its original shipping box to eliminate a possible MB to case short.
The PSU and case are known to be good. They were successfully tested with a GA-790X MB
Tested configurations:
1. ALL components in place
2. CPU, GPU, 1 stick Ram in each different DDR slot
3. CPU, 1 stick RAm
4. CPU only
In all cases, then same result. I can occasionally get a power on to hold but receive continuous beeps. When this happens, all fans will spin up. Also, when this happens, the main PSU on/off must be used to turn off. Another attempt to power on immedaitely after this fails. If it is let to sit for 10-15 minuites, I can occasionally get a repeat of this activity.
I fear a DOA board
Recommendations appreciated.
