I see the CPU has onboard graphics so you only need the board, PSU, one stick of RAM and the CPU+HSF to see a boot screen. No other parts required.
This is my first build, and I have no idea what's wrong. I plug in the power and turn on the computer. Everything lights up, the fans start spinning, (no sounds or beeps or anything) but then after roughly ten seconds it shuts off. Then a couple seconds later starts back up and continues this until I cut the power. I'm guessing something may not be compatible but honestly I have no idea. It has:
Gigabyte GA-Z170X-Gaming 5 motherboard
Crucial 16GB 8GB x 2 DDR4-2400
MSI GeForce GTX 1060 Gaming X 3GB
Corsair CX650M 650 Watt ATX Modular power supply
Intel Core i7-6700K 4.0 GHz
Crucial MX300 275GB 2.5" SSD
Cooler Master Hyper 212 LED CPU Cooler
And a 1TB internal hard drive. And I believe that's it. If there's anything that I might have done wrong or anything that anyone can do to help please tell me, everything is appreciated.
