My PC will not boot unless I turn on the computer and then press the restart button on my case. I have just finished switching from my old case to a Corsair Obsidian 450D. I've plugged in all front panel connectors, fans, and all of the cables that were plugged in in my old case and I'm about 99% sure they're in the right place. When I first press the power button the fans start spinning and all the lights on each part turn on, but nothing displays, but when i press the restart button after its already on it boots like normal.

Parts:
Case: Corsair Obsidian 450D
Motherboard: MSI Z170A XPOWER GAMING TITANIUM EDITION
GPU: NVIDIA RTX 2060 Super
CPU: Intel i7-6700K
RAM: 2x16gb (32GB)
PSU: EVGA SuperNOVA 750 G2
