I just put together my new build with all new parts: Asus Maximus Viii Extreme motherboard, Xeon E3 1275v5 LGA 1151 processor, G. Skill tridentz DDR4 3733 RAMM, Samsung SSD 850 pro. My power supply, Corsair AX860, is about 6 months old which was powering up my old rig without any problems. As i've tried to install an OS using an USB flashdrive my new build doesn't send a signal to my monitor using its HDMI port. My mother board lights up as I switch on my power supply, both the CPU and Power Supply fans turn on but quickly turn off as well as the rest of the lights and QR Code 00 which isn't used. Now I noticed when I have the 8 pin EATX12 V power plug disconnected the computer starts up just fine without any fans or lights turning off and QR code stays on at 00. This is my first build with all new parts so I'm not sure what I have or haven't done right. I'm now just trying to start up my rig with little to none peripherals to at least start the bios setup before installing the rest.
