Newly built PC not posting

timb1226 · 27 Aug 2019 at 20:18

Recently built A new Ryzen system, managed to use for a good week. Seem pretty stable throughout my use.

However, all of a sudden this evening when I turned it on, everything turns on but no display on the monitor. All the fans including RGB from GPU and AIO come on.

Attempted to resit ram sticks into the different slots + using one at a time but to no avail. Also debug light lights up DRAM. Highly likely but it's the RAM, but is there any other way to figure out the other problems before I rma this RAM. Also, is it normal to have both RAM fail together or is it pointing towards that my mobo is the faulty one?? Or even CPU??!?! Anyway I'm really clueless here and of be very grateful if somebody could assist me. Many thanks!!

My specs are as follows:
CPU: Ryzen 3700x
Motherboard: gigabyte x570 aorus pro
Ram:Corsair vengeance 3600mhz CMK16GX4M2D3600C18
PSU: evga G2 750w
GPU: Nvidia 2080 super

Edit: Supposedly the ram that I have is not compatible with Ryzen but it is not Ryzen rated. Is this a likely problem??

Bump, help please

Which cooler are you using and would you say there's a chance it might be tightened too much? This can cause a bit of board warp over time and often affects the RAM. The symptoms you describe fit the bill, i.e. PC starts, fans running, but no display and RAM debug code.

Back to basics, remove everything and re-seat all, plugging in only essentials and like you tried 1 stick at a time see if you can get it to post.

I use h150i pro. I tried resitting and even taking the motherboard out, and using amd CPU fan. But same problem manifests. I highly suspect RAM but is it normal that both sticks are busted. I tried each stick individually and all the different combinations but nothing. Either ram or mobo? Is there a more specific way to rule out mobo and CPU?

Tried almost everything but nothing

You could have two knackered sticks, possible but highly unlikely. Have you re-seated the CPU also?

Can you borrow another stick of ram to rule that out?

Yes I have reseated CPU, even used default fan that came with CPU. Both sticks being busted is supposedly unlikely. Now it makes me think whether mobo is busted out even CPU.

Unless you have spare components to swap out test its a hard one, what about PSU can you change that out?
Does your mobo have onboard LED diagnostics and if so does it give an error code?

I assume you did a full reset of the CMOS including removing the battery from the board? If so I would then proceed to use the BIOS flashback function on the motherboard to flash a new BIOS to it, and see if you have the same issue.

Here's a link to the latest version for you.

Yes attempted to clear CMOS via battery, clear CMOS jumper but no post. I tried flashing as well but to no avail.

What happens if you try to boot with out RAM?

timb1226 · 29 Aug 2019 at 13:13

Nothing. Dram led still lits up as solid red. All fans and lighting turns on but no display

It should post with no RAM, could be the CPU.

labcoattech · 29 Aug 2019 at 14:47

Are you able to try with another GPU?

Not sure if serious.

Have you tried the backup BIOS on your board?

Don't think x570 has such thing, and not exactly sure how to do this. Its starting sound like it's more likely to be mobo

In your considerable experience have you ever known a motherboard to post with no RAM?

Yes, but nothing you'd buy as a consumer.

Hey fellas tried qflash plus but nothing also. Huge feeling it's mobo now. It's under 30 days so hopefully I can get it replaced with no hassle
