I built my first computer and when I turn on the power, it shuts down automatically. The CPU light turns on briefly, prior to shutting down. Here are the parts list: * Corsair Obsidian Series 750D Case * Corsair Hydro Series H90 140mm CPU Cooler * Corsair Vengeance LED 32GB (2x16GB) DDR4 3000 (PC4-24000) * GIGABYTE AORUS GA-Z270X-Gaming K7 Gaming Motherboard LGA1151 * Intel 7th Gen Intel Core Desktop Processor i7-7700K * GeForce GTX 750Ti This problem has happened several times and I have reapplied thermal paste and made sure that the pins on the Motherboard, where the Processor is seated are not bent. Thermal paste was applied using pee method in center of processor. I've plugged in a PC Motherboard Internal Speaker, and it does not make any beeps. I have tried two different mobos (same model) and two power supplies (EVGA Supernova 750B2 and Corsair AXi Series, AX860i). I have also done the paperclip test on both and both PSUs are operating correctly. The DDR4 are plugged into slots marked 1 & 2, as per mobo manual. I have triple checked that all necessary cables are plugged in fully to both the PSU and mobo. I have also tried to boot up the computer w/o graphics card and hard drives. All components excluding mobo, processor, and H90 water cooler were installed in another tower and functioned correctly. Please advise.
