New Builder: No Beep/Display/POST

Hello,
I'm trying to make a budget build. I got everything assembled and in the case. When I power the computer on, all the case fans power on, as well as those for the CPU, GPU, and PSU, so I can only assume that those components are at least powering on. Everything looks fine to me, but when I connect a monitor, I get No Signal. I connected the motherboard speaker and powered on again, but there are no beeps whatsoever.

It is probably worth mentioning that this is the second computer I've ever built. The first went completely smoothly and I had no problems whatsoever. As such, I never needed to connect the motherboard speaker to check for problems, so I don't have any idea what the beeps sound like. I would assume that I would have heard them distinctly if I held my head a few inches from the speaker when powering on, correct?


Here's my system build.

As an aside, would it have been smarter to go with a Core i3 build instead of AMD? It would have costed a little more but maybe it would have been a better idea?

Some things I've tried:

  • ■ Removed every single component and attachment from the motherboard except for the CPU, CPU fan, PSU, motherboard speaker, and power headers from the case. I powered it on again and still got no beeps.
    ■ Ensured that all the motherboard standoffs were properly installed.
    ■ Ensured that the RAM, CPU, and GPU are properly and firmly installed. Yes, the RAM is in the first slot.
    ■ Ensured that the headers are installed with the correct polarity alignment.
    ■ Resetted CMOS.
    ■ Connected a different monitor and tried DVI and HDMI outputs in addition to VGA.

Some observations I've made:

  • ■ The PSU is modular and came with a VGA cable, which I would presume is for the graphics card, correct? There is no place to attach any such cable to the GPU, so I just discarded the cable. That's valid, right?
    ■ The CPU/fan did not come with thermal compound, so I just installed them without it. I figured this would be fine since the computer will only be used lightly. There's no way that the CPU could, like, somehow detect the absence of thermal compound and subsequently not start, right?

From what I've been reading, I've gathered that my only realistic option at this point is to replace each of the components, one at a time, with components from my current computer that I know are working. Is that really the only option I have left? I just wanted to make sure before I went ahead and did it because that would be a lot of work.

Also as I said before, I'm relatively new to building computers, so if you have any general advice for me about anything at all then by all means please throw it at me. I need all the help I can get.

Ugh. I'm stressing out man, haha.
Thank you so much for your time!

Yes! The cable from the PSU splits into two 4 pin connectors. I assumed that it didn't matter which one I plugged in since they were not differentiated, but I tried both just in case and still got the same result.

Okay! I'll try these out and see what happens. Thank you so much for the help!

Okay, so I tried the power supply from my working build and got nothing, and I breadboarded the motherboard and still got nothing. So at this point, it has to be the cpu or motherboard that's bad, right? Is there any way to distinguish between which it is, or do I just have to return both?

I assume you are connecting the monitor to the gpu and not the io correct?
Also, AMD systems can take a while to post their first time. Have you given it several minutes after you boot up to get past that point?
Are there any debug lights on you mb?

Really? I waited a good 2-3 minutes on boot, maybe 4. I figured that if I got no feedback whatsoever as far as the monitor or the speaker after a couple minutes then something was probably awry. Maybe I'll put everything together one last time and try it once more before I return the parts.

I don't recall seeing any lights on the motherboard after booting up, but I suppose that is probably also worth checking the manual and everything just in case.

Also, yes, I plugged the monitor into the gpu. The motherboard has no onboard graphics.
Thank you for the suggestions!!

2-3 minutes should be enough. If you’re still able to bring the components back to the retailer, then that’s the best option as alexiou suggests. I really like to exhaust all other possiblities before I start an RMA.

Okay! I'll just go ahead and do that. And no problem, again I really appreciate the help!

Hey, one more quick question. If I'm returning (RMAing) the CPU, should I like wipe off the thermal paste with a paper towel or something? It came pre-applied, so....
I just don't want to do anything to jeopardize them exchanging these parts for me. Thanks!
