PC starts without using start button, Postcode 00, and solid red light on CPU

[Ayush K]

Greetings everyone,

Last Friday I was just casually playing GTA V in my PC. After that I turned it off. Then when I turned it on again there was nothing, no power, no spinning fans, no postcodes, etc. I followed dozens of troubleshooting steps like checking all connections, reseating the CPU and memory, removing and reassembling all the components and more. After I jumpstarted the PSU and plugged it back in the motherboard, it just starts up, I do not even have to switch it on and since then the CPU red light is on and the post code is 00. Here's a short clip on what's happening. (If you are wondering why I removed the CPU cooler, it is because I was curious if the CPU is getting warm or not, and it sure is.)

CPU is AMD Ryzen 7 3800X

GPU is MSI Gaming Z Trio RTX 2070 Super

Motherboard is Gigabyte Aorus X570 Master

RAM is 2*16GB G.skill Trident Z Royal

PSU is Thermaltake Toughpower Grand RGB 750 W

SSD is Gigabyte Aorus PCI-E Gen 4 M.2 ( Wasn't plugged in when I shot the clip)

2nd SSD is Kingston A400 Sata M.2 480GB (Also not shown in the clip)

AIO (this neither) Gigabyte Aorus 360 Cooler

Let me know if you would like to see the other stuff (I mean why would you but still).

Since it started powering back on, have you had the CPU cooler re-installed, and does it still exhibit the same behavior?

Yep, it's the same. I thought the CPU is dead and so removed the cooler and tried touching the CPU. It was warm.

[Aaron_T]

Well, warm doesn't necessarily mean functional, just means that power is flowing through the wall -> psu -> motherboard -> cpu.

 

It sounds like you either have a problem with your motherboard, or your CPU. I'd start by removing the CPU, getting the latest motherboard BIOS version, and using that boards Q-Flash to try and update the motherboard BIOS to the latest version.

 

Then you'll know one of two things.

1. If the Q-Flash works, then reinstall the cpu and try again, if it still doesn't boot then it would point to CPU, and getting a donor chip from a friend, family, craigs list, etc to pop in and test would be a good next step.

2. If the Q-Flash fails then it would point to a motherboard issue, and from their either get a donor motherboard to test your CPU with, or just try to get the motherboard RMAd

 

Keep in mind the above are not guaranteed, and if possible, having donor parts to test with is always the best way to figure out which part is broke.

So how am I supposed to use the Q-flash? I've seen Linus build a lot of PCs and that's how I was able to build mine. I don't know a lot about computers.

@Ayush K

This looks like a good tutorial on it.

Just keep in mind, you have a different motherboard than the tutorial, so make sure you're getting the BIOS version specifically for your motherboard.

Thanks, I'll get to work.

I am on the webpage and I see 11 Bios here, which one do I have to use?

@Ayush K

First, I noticed that there are multiple revisions of your motherboard, so be sure that you are on the support page for the revision that corresponds to your motherboard.

 

Once you are sure you are on the correct motherboard revision support page, then you'll want to get the latest, most recent, BIOS version for your board.

I looked in the manual and checked the board, the revision is 1.0. and the most recent i see is F33a. Is this the one?

I am a little scared now as the site says that doing so is risky and it can be problematic so just one last question: Should i really do it myself or should i go to Gigabyte's service center and get it checked there?

Yes, the warning is accurate, it can be risky, if the power goes out it could cause more harm than good.

 

If you have a Gigabyte service center in your area that you can go to(not something most people have) then yes, by all means that makes a lot more sense to let them take the risk! Haha.

 

Before you go though, I think your motherboard has a dual BIOS feature, it may be worth while trying to switch to the secondary BIOS.

Thanks, I will take it to the service center tomorrow.

But for now how do I switch to the second bios?

I am trying to figure that out ...

 

Your MB spec page shows support, but I am not seeing any details in the MB manual...

 

EDIT:

This reddit thread explains where the DUalBIOS switches are on the Master:

It's the first response... if your board isn't in dualbios mode already, you won't be able to try

Should I check in the physical manual then?

The response to this reddit thread talks about where the switches are for your MB:

If your MB isn't set to "dual mode", described above, already then you won't be able to switch to the second BIOS now.

Are you trying to point out these two switches? if yes then yeah I have tried messing with them with combinations 1,2 2,1 2,2 and 1,1 but the outcome was same everytime, post 00 and CPU led red.

Okay, yeah looks like it's a trip to your Gigabyte support center...

 

On the plus side, they may have parts there that can be used to swap out and test your system more thoroughly.

There was no support center there but a collection point. The nearest service center was in New Delhi so it took some time. Just got it today and it is up and running! Thanks for your help!

Glad you got it straightened out! No go play some games!
