Just built this machine, it has never posted and i am getting a FF code on motherboard.
To save some time i will list steps i have tried:
1. Tested power supply with a Thermaltake power supply tester, all voltages are within range, including the CPU power connector, which i did double check to be plugged in.
2. Tried the video card in another PC, working fine, also tried it in each pci express slot (four of them) on the 990fxa-gd80 board.
3. Tried resetting the bios and have also tried booting with just one memory stick in Dimm slot 1
4. Tried powering up the board out of the case with just the power supply, video and memory connected.
5. Decided that i had a bad board, rma'd it and received replacement. same problem again.
6. Tried booting with different keyboards and with no keyboard.
7. Discovered that one of the system fan power plugs doesn't work, think it was #4, not sure what this means.
8. Tried a different brand and speed of memory, also put 2 sets of kingston hyperx ddr3 1600, to use both memory channels.
9. Have uninstalled, inspected, cleaned and reinstalled the CPU and CPU cooler which is the stock AMD cooler that came with the CPU.
Thinking that maybe a bios update would solve all my problems, but can't boot into bios to update it, get the ff code immediately on power up.
I'm open to any and all suggestions and i am out of ideas.
Additional info. The north bridge leds are lit up to phase 2, the CPU phase lights are lit all the way to 8, the ddr phase led is lit on phase 1.
