PC not starting

[Moparbro]

I'm pretty sure my PC has kicked the bucket. I tried to turn it on, pressed the power button and it flashed on for literally 1 second, leds fans etc but then went dark. I tried unplugging all the cords from the I/O and booting it up again, It did the same thing except I noticed the diagnosis LEDs on my motherboard (MSI B450M Mortar Max) all flashed. I don't know if that's something that happens whenever you start it or if it means everything is dead. 

If anyone has had something similar happen or has advice please let me know, I don't really feel like spending upwards of $300 on replacement parts

Any post code beeps? assuming you have a speaker attached.

After flashing they stay off? Nothing comes back on?.. Are you running dual sticks of RAM? If so will it post with one stick only?

Yeah they all flashed once and then nothing, I am running dual channel ram so I'll try without one stick
