Hello, I have a problem with the motherboard z97 m power mac, code 03 comes out at startup and after a change from the bottom of the other BIOS it starts. I updated to the last bios, I changed the frame with only one tile. I removed the video card. I read 2 other topics similar from the forum but never managed to find a solution. the configuration is with intel i5 4670, ram kingston xyper x fury.
