Question HELP, My custom PC isnt recognized on TV.

[TheCocoaGamer]

Hi there!

So I had a problem with my custom pc build, the CPU,DRAM,VGA, and BOOT lights have went white, in order, staying on BOOT, and when i plugged in my gpu to the tv with HDMI i still had no signal. I tried without the gpu and still same result. I will share specs and a gif of the pc

SPEC:

MOTHERBOARD: Msi Z490 A-Pro

CPU: intel i5 10600 K Comet Lake

RAM: 1 stick on 3rd slot : g. skill aegis ddr4 f4-3000c16s-8gisb

GPU: Nvidia Geforce RTX 3060

PSU: GameMac RGB-750

Tv is a modern Vizio

Ive also added pictures below, I hope it works

Thanks in advance for the help

Page 27 of your manual:
"Always insert memory modules in the DIMMA2 slot first."
Which is the 2nd slot from CPU

id expect ud have video signal issue with riser on x1 slot

 

[TheCocoaGamer]

Ive tried to put the memory module in the 2nd slot (and the 4th and 1st) and none worked, Ive also tried to directly put the gpu on the pci #1 slot but both did not work, thank you for your input though, any more ideas?

 

[egda23]

Do you have access to another PSU ?

 

[TheCocoaGamer]

I do, but its the same type, Should I switch everything out and use it? Everything seems to be powered on bc of the lights and fans they have.

 

[kerberos_20]

okay, put windows installation in usb (or linux bootable usb), then start up your "PC"
if boot led goes away then your gpu doesnt detect your display
either cable is bad or your TV is sending invalid data (edid)
so u may need another monitor or cable

 

[TheCocoaGamer]

Ok, ill try that, but should the bios screen be showing? I wanted to see that to make sure my boot usb worked, although it should since i used the tool. I also know its not the cable, since it worked with another device, so Ill try another tv to see if thats the issue.

 

[egda23]

Do you have to select the entry on this tv or is it completely auto?

bios doesnt need display...its nothing unusual to see black screen on bios, once in windows all should work well...but without OS u may want to see bios afterall

 

[TheCocoaGamer]

I have to select the entry (hdmi 0/ hdmi 1)

However I think I found the problem, when I kept the power to the gpu and riser, and instead connected the riser output to a different pc, it still couldnt connect, meaning that the gpus arent working with the motherboards I have, is there a way to tell if its the gpu or the riser? I have 3 gpus lying around and around 3 risers, and they all share the same problem.

Also, I know most bioses should show a black screen, but It should still detect a source from the tv, instead of no input.

 

[egda23]

This becomes really confusing
Are you saying that none of you 3 GPUs works with none of your 2 motherboards ?

 

[TheCocoaGamer]

Yes, so to give more information, I had recently gotten these 3 gpus, and this motherboard. I had another pc, with a gpu and motherboard. I took apart the old pc, and used the new gpus on both the old and new motherboards. No dice. I had also used my old gpu on the new motherboard. Also no dice. But both my old gpu and old motherboard work, as I put it back together and it is working 100%. So both my new motherboard and my new gpus arent working, and I have no idea why.

Are these "new parts " really new, or a set possibly worn out by mining ?
Did you try the new mobo with the old PSU ?.

 

[TheCocoaGamer]

UPDATE: I did something weird to see what was happening, so I had connected my new gpu in my old motherboard in the PCI #1 slot, with the hdmi running through the GPU. I had then used my riser to connect my old gpu to my old motherboard PCI #2 slot. When I did this, the old motherboard turned on, however it was using the motherboards graphics. I also found it interesting that task manager did find my old gpu, despite it not running (and it did not find the new gpu plugged in PCI#1, despite the hdmi running through it.)

The gpus could be worn out, as I had gotten them from someone saying that they recently opened from the box, and comparing with my gpus the claim seems to hold, and the motherboard is straight out the box new.

I had not tried the old PSU with the new motherboard yet, despite it powering everything could it be the problem? It would explain why my old gpu didnt work on the new mother board, but it still turned on. It also doesnt explain the gpus.

Thank you for your guys input, its really helpful.

 

[TheCocoaGamer]

Another Update: I did the weird thing as above, but replaced the old gpu with a new one, and the same results occured, however instead of picking up the old gpu that wasnt doing anything it picked up the new gpu that wasnt doing anything. This is me putting the new gpu in the PCI #2 slot with a riser, and using a new gpu in the PCI #1. PCI #1s gpu gets ignored, and although PCI #2 is not doing anything, it will get detected by the pc (everything is powered on and seems to be powered, the proof being LEDs and fans.)

 

[TheCocoaGamer]

Scratch that, it just turns out one of my new gpus seems to work fine on my old pc. To give info on gpus, I have a
RTX 2060 (old)
RTX 2070 S
RTX 2080 S
RTX 3060

The last three are new, and the one the works was the 2080S. This leads me to believe there is something wrong with the 3060 and the 2070, but it still doesnt explain why the old motherboard doesnt work with any gpu, and eveything seems to be powered and working.

 

[egda23]

So, I would take the old mobo and test each GPU with the old and then the new PSU. Without any riser.
Do the same with the new mobo.
And put the RAM in A2

 

[TheCocoaGamer]

Ok, after doing all that the only things that have seemed to work was my old mother board , the 2060 and the 2080S

the new motherboard did not work at all, along with the 2070S and the 3060.

 

[TheCocoaGamer]

I did use the old psu for the new motherboard, and it worked fine

 

[egda23]

I did use the old psu for the new motherboard, and it worked fine

and with new PSU on the old mobo ? And the new mobo with old PSU ? that would conclude the testing

 

[TheCocoaGamer]

*other way around sorry, i used the new psu on the old mobo, i have not used the old psu on the new mobo yet, but i will tommarow as its like 2am here lol

OK. Good night

 

[TheCocoaGamer]

Gn, will report tmrow

 

[Adam0ne]

It could probably be a PSU problem. Probably having a hard time sustaining powerdraw of 3060.

Find other PSU's you can borrow to test. Test first without the riser.
