I used to get a blink code saying power supply issue. Replaced it, only to get a motherboard failure code. I replaced that. Now I get constant blinking for about 10 seconds, then a pause. Then two blinks, two blinks and a pause, then just repeats. It never boots. I've replaced the board, twice, power supply, memory and video card. Even the cables. The only thing not changed are literally the case and processor. I can find any other discussions about this, and I'm losing my mind. I've even reset the CMOS.
