I just purchased this 990FX to upgrade from a gigabyte 990fx ud3 MB, my rig is as follows .. 

PROC: AMD FX8350 Black

MEM: GSKILL 1600 8GB x4

VID: Sapphire AMD R9 270x 2GB x2

HDD: Samsung 850 EVO 500GB SSD

Cooler: Corsair H80i all in one water Cooler

PSU: Corsair HX850i 850 Watt

ODD: Sony DL DVD RW SATA

MB: ASROCK 990FX Extream9 (bios 1.80)

The Issue:

As stated this system was up and running fine with the gigabyte board with all above hardware running windows 7pro 64bit. I replaced the mb and powered up the system, the mb posted and began booting into windows displaying the pulsing windows logo after a few seconds the system simply powered off. I pressed the power button to turn it back on and the system did not do anything. I then switched off the power supply and held the power button down for 5 seconds to fade the flea power out, then switched the power back on to the power supply and pressed the power button again and the system booted just fine displaying the windows safe mode menu. I selected the safe mode with networking option so that i could take a look in the logs and see why it powered down. Windows did in fact boot all the way to the desktop via safe mode but the logs showed no errors as to why it shutdown. Figureing that it was just a fluke i restarted to normal boot and POOF it did it again ... and again .. and about 10 more times before i gave up. So in order to figure some things out i removed 1 video card and tried again .. same result. I then removed the harddrive and inserted a windows install usb and tried to boot to that .. same result ... the only thing i can get to boot fully is windows safe mode. Thinking that it was some weird issue with the fact that i swapped MBs on the OS currupting something i formatted and removed all partitions of the SSD and tried to install a fresh copy of windows ... FAIL! i cannot get the install to boot. i even tried the bios internet flash thinking that maybe it was a bios issue (telling myself no this could not be the reason since safe mode  boots ..) it reported that the bios was upto date. so i removed all but 1 stick of memory and rebooted moving the memory stick into each slot with each attempt failing .. i then tried 2 sticks skipping a slot each rotation and still every attempt fails. i have ruled out video, memory, hdd, i cant for the life of me figure this out ... it has to be some wierd bios settings in this MB that needs adjusted i just cant figure it out please help!!

NOTE:

DR Debug also does not show any errors.
