Question Newly built gaming PC troubleshoot help?

[Jasutin]

I recently completed my gaming build last night, and when I turned my PC on for the first time, it booted up successfully to the BIOs screen. But after a few seconds, the monitor goes black and my PC turns off. Every other attempt at turning on my PC after the first time results in the PC turning on for a split second (fans, LEDs and such), and then turning off. I’m a bit stuck, and I don’t know what’s the issue here. Any PC gods want to help out?

Attempt to turn PC on

TL;DR: PC not booting up anymore (after successfully booting up to BIOs and turning off after a few seconds)

The first thing I would do would be to go through and make sure all the connectors are plugged in tight, reseat the ram, and try again.
If your motherboard came with a speaker you might plug that in and see if it's throwing a code, or check LEDS if equipped.

^This, especially the front panel connectors at the bottom of the MB.

Nothing in your spec indicates a MB BIOS update would be required, so connectivity is the first thing to check.
