Still Won’t Boot

ForeverAutumn · April 7, 2020

Hey nerds,

So, I just "finished" my first PC build again. I had this problem before but got word I probably had a bad/mediocre psu so I bought a new one. I've linked all the new parts I used below. Yet I’m still having the same issue.

At first, I turned on my power supply and pressed the power button on my PC and all the fans worked, the RGB came on, all was well with the world, and then it just shut off. Didn't even make it to post.

When I try to turn it back on, the top EZ Dedug LED flashes once (red) , followed by the flash of the other three lights (also red). The tiny motherboard fan at the bottom also begins to spins but stops almost immediately. It all happens very quickly, but I've attached a video of it anyway. Even though it started it up with no problems the first time, I can even get it to turn on now.

Any ideas on what might be wrong and how I can fix it?

Thanks guys, all advice welcome.

Cheers.

You certain the mobo supports the CPU, was the BIOS up to date before you put it on (assuming it's actually supported that is)

X570 boards are compatible with 3rd gen Ryzen out of the box. That shouldn't be a Mobo issue

I'm sure they are compatible. As for the BIOS version, I'm not sure it's up to date. How can I check without being able to turn on the computer?

Well, you can't. That's one of the issues. What you *could* do, is find the mobo maker support page, find the lowest BIOS version, assume that is the BIOS on your board, and find which CPU is supported by said BIOS version, then beg/borrow/buy/steal said CPU, put it in to the mobo, and see what happens.

I would suspect a local computer shop would have a chip you could borrow for 5 minutes to test with. At the shop I worked, we did this all the time.

But if you are certain the BIOS is up to date and should work with your CPU out of the box, then we need to look elsewhere as a cause of your issues.
