Question New PC has no display, local PC repair shop useless ?

[Doctaoctagonza]

Hello i finished building my pc on Thursday only to be met with disappointment. It turns on and from what I gather they are working as all components fans are working as well as case fans and things that light up are lighting up. But I'm getting no display and the vga and boot motherboard leds are on. Everything was new except my case, cpu cooler and nvme drive. (I forgot to reformat before building)

I've tried resetting the cmos. I've tried unseating the gpu. I made sure my display port and hdmi were plugged into the gpu. I've tried plugging the hdmi and display port into the motherboard. I tried one stick of ram in every slot. I tried no gpu at all while plugged into the motherboard, I tried taking the pc apart and rebuilding it again. I tried taking the nvme out that had my OS on it. I tried having no drives plugged in at all. I tried turning on/connecting the monitors after he system was already on.

I had no idea what to do t this point so I took it to local pc repair and they basically wasted my time for a week and said they have no idea. (I live in small town Kentucky so I didn't have much expectations) I go back to pick it up tomorrow, what do I do from Here I'm at a loss and I'm completely heartbroken after finally getting money for parts and it not working. Do I send in the mothrboard for a rma?

Best thing to do: breadboard the system (which i guess you didn't to beforehand? 🤔 ).

Meaning:
MoBo out of the PC case. Set it on any cardboard box.
Have CPU + CPU cooler installed.
Have 1x stick of RAM on the MoBo.
Connect PSU power cables to MoBo (24-pin ATX and 4/8-pin EPS).
Connect monitor to MoBo.
Connect KB and mice to MoBo.

No other components are needed, like GPU or OS drive. So, uninstall all other hardware.

Power on the build (shorting PWR + and - pins on MoBo by screwdriver) and look if you can get an image on screen.
To power off the build, flip the PSU switch at the back of the PSU.

If you do get and image, great, CPU-MoBo-RAM combo works.
If you do not get an image, one of the three (or all three) are dead: CPU, MoBo, RAM.

To validate which of the three is dead, you need 2nd, compatible system, to individually test which of the component works and which doesn't.

I don't have a second system to be able to test anything in the event it doesn't work wo I'm not sure what to do 🙁 but I will try breadboarding

Only small test that you can do during breadboarding is to, somewhat, validate if it could be RAM issue. Whereby you 1st try with stick #1 and if no image, try with stick #2. Chances that one RAM stick is bad, are possible. But both at once, are slim. So, 2nd stick may work. But if no image still, then i'd replace MoBo, because MoBo can be DOA and is usually the one that dies.

If you do end up with new MoBo, do not build the PC into the PC case, instead do the breadboarding again. Since breadboarding is easy way to validate if CPU-MoBo-RAM combo works. If they do work, you can then fully assemble the PC. But if not, then you can easily take it apart; compared to when you've already fully assembled the PC inside the PC case + cable management.

Breadboarding would look like so:
(This is my Skylake build breadboarded, when i bought the components. Full specs with pics in my sig.)

Do you think if I go to best buy and buy a new mobo today it will fix it? I'm worried about getting a new one and needing to update the bios for it to work as I don't have another pc to download the update

It should, IF the issue is with MoBo and not CPU or RAM.

Btw, running Ryzen 7000-series on AMD 600-series chipset doesn't require BIOS update.

Now, if you'd have Ryzen 8000-series CPU, you many need to update MoBo BIOS. But MoBo BIOS versions list doesn't say that you need to update BIOS even when having Ryzen 8000-series CPU.

Maybe I give it a try I'm just worried whatever new mobo I get will need to be updated or the mobo isn't the problem 🙁 I'm so overwhelmed

7800X3D requires BIOS update 1.21 or later.

I said that the repair place updated it snf it didn't change anything in another comment

 

[Aeacus]

7800X3D requires BIOS update 1.21 or later.

No, it does not. What v1.21 does, is optimizing 7000X3D usage, but CPU still works even when BIOS is initial release of v1.18.
