Starting to question whether the board is damaged now after that BIOS flash attempt.
I've tried :
Reducing RAM to one stick(used both sticks alternatively), in different DIMM slots.
Removing connections and power to the optical drive and the SSD.
Removing any usb or ps/2 peripherals.
Removing CMOS battery for ten minutes, and moving over the motherboard jumper.
Swapping out different video cards in different PCIE lanes.
Removing video cards entirely.
Swapped out for another PSU.
So with one stick of RAM, no, no peripherals and no drives, the computer starts, then quits immediately. Two seconds later it fires back up. Fans are going, CPU test passes, MEM test passes, VGA light goes red and stays red.
I get no beeps.
PSU seems good though because if I remove the RAM stick, I get the usual beep sequence.
In my mind's eye, I'd like to think that the solution is to reset the CMOS, but as mentioned above, I thought I would have already done that.
If the CMOS has been reset, then all I can think is that the BIOS flash hurt the board.
Someone a few pages back talked about it happening to them, I didn't see if they got it solved.
EDIT: Forgot to mention that sometimes when I start the computer, it powers off and back on like mentioned above; and then after I manually power down, it seems to the auto on/off sequence at random. At first I thought it was the BIOS flash stuck in it's own loop or trying to complete itself, but if that was the case, surely I'd have visuals at least.
