New computer failed start issue

[RyanChase]

Hello!

Issue: New computer built last night starts and full revs on fans and shows an orange LED (checking memory) fans then go to normal speeds and it then goes to a red LED (checking CPU). It will either restart again with the process above and repeat that process or go to a white led (signal check) and then green LED (post) and boot to the MOBA bios entry screen for a second before restarting to the thing above.

Tried: Tried different memory layouts down to one stick, checking the CPU mount, checking the PSU connections, and trying to get into BIOS.

Thought: I'm thinking that it's either a motherboard issue or a CPU issue but any and all thoughts are appreciated. Likely the prior.

Thank you!

Have you updated bios on the motherboard?

Most of those B450 needs a bios update (so I hear) for 3rd gen ryzen cpus.

Is it a clean install of OS?

gpu is igpu? source needs to be on and right one before turning on pc or will not post.

 

turn it off and give cords a push sometimes a loose one can cause issue happened to me a bit.

 

if these fail, either bad part or a mobo that needs an update to use that cpu. for example the z390 board needs 2 bios updates to use a 9900k.

The MOBA says it's ready for gen3 out of the box and I can't flash it without a different CPU.

GPU. Have the video input connected from the GPU to the monitor and it does display the menu to go into BIOS for about a second before the computer restarts again. So it defiantly can send signal.

 

I've already tried checking all the cords and even booting with some non-essential items unplugged.

 

One thing I did notice is that on this motherboard it has two LED zones. One in the upper left and one in the bottom right. HOWEVER only the upper left ever does anything so I'm starting to think power is not being delivered to a section of the MOBA meaning it might be a bad MOBA.

Try to remove just your NVME drive and see if the starts up and is stable or not.

 

If it does work, then it's a BIOS and a simple update (from within the BIOS itself) should solve that.

(This is from experience, my ROX Strix x570-I would not even post with the nvme drive, I had to remove that, get into BIOS, update it, then slowly get everything working).

[RyanChase]

Sweet I'll give that a try in a bit and report back. Thank you

Gave it a try and also unplugged the harddrive. No luck

Pity, would have been cool if it worked on the first go.

 

I'm guessing that all of your parts are brand new right?

Have you tried to reset the BIOS?

If not, do give that a try - but also remove the CMOS battery as well (the pins are sometimes weird).

 

Though, from what you've said it may indeed by a faulty motherboard.

Is there a way to do that if I can't even get the MOBA to post for more than a second at a time? There's no flash bios button on this MOBA so I feel I'm sort of out of luck.
