Question Booting problem

[DeXtRa7577]

Hey so I have a asus crossfire vii hero motherboard, ryzen 7 2700x, 2x8 gigs of ram, a sapphire pulse radeon rx 5700 xt, a 1000 wat corsair power supply, and a corsair icue h100 rgb pro xt aio.
I can't get my computer to boot I turn on the power supply and the motherboard lights up bit when I got the power button the graphics card will light up for a second then turn off and it won't boot. None of the fans or anything will spin, I thought it was the power supply so I had gotten a new one and it's still does it. I'm so lost on what is wrong can someone help me with it please.

Welcome to the forums, newcomer!

Model for your Corsair PSU? Is it recycled from an older system? If so, how old is the unit? Given how the processor you have comes with a stock cooler, see if you can work with said stock cooler and with only one stick of ram, placed in slots A2.

The psu is a hx 1000 and it's brand new I actually just installed it and I'll try that

Alright I put the stock cooler back in and with one stick of ram and tried both of them the cpu cooler flashes and spends a second then it's everything turns off again
