This is my first custom build, and I'm having an issue where it powers on for about 20 seconds, then restarts. I've done everything on this checklist (except for the breadboarding and the PSU swap), and nothing has changed.
Here are the specs of the new machine:
Motherboard: Gigabyte GA-Z170X-Gaming 7
CPU: i7-6700K
CPU cooling: Cooler Master 120M (water)
Case: DIYPC Skyline-07-B (full ATX tower)
GPU: EVGA GeForce GTX 960 (2GB) [I must note that I have removed the video card for troubleshooting, using the on-board graphics instead, and that the issue occurs with or without the video card)
Memory: 2 8GB sticks of DDR4 2133Mhz RAM
PSU: 600W Thermaltake TR2-600NL2NC
Hard Drive: Kingston 240GB SSD
It also has a DVD drive, but when I have it connected, the machine only stays powered on for about half a second, so I'm leaving it disconnected while I'm troubleshooting.
Before my machine automatically restarts, whatever device is plugged into the CPU_OPT connector on my mobo has a sudden "boost".
The reason I say "whatever device" is because I was confused with my water cooler which plug (radiator fan plug or the water pump plug) went into which connector (CPU_FAN or CPU_OPT). When the radiator fan is plugged into CPU_FAN and the water pump is plugged into CPU_OPT, the blue LED light on the water pump gets brighter right before the computer shuts down. If I have it reversed (radiator fan plugged into CPU_OPT and water pump plugged into CPU_FAN), then it's the radiator fan that starts spinning much faster and louder right before the shutdown occurs.
This is starting to seem like something involving fan controls, my BIOS, and/or CPU temperature, but because I'm still not getting any video output, I can't alter any BIOS settings (unless there's another way).
I've been stuck for weeks now, so I'm desperate for any direction someone can give me. Really hoping to get this new machine for my dad working by Christmas, but if not, ASAP.
