Pc not posting

[Benis23]

So last week i bought me some parts and built the pc then when i powered it up all the rgb lit up but nothing showed up on the display and then me and my dad got it to work somehow but then it did it again yesterday but now i tried everything and nothing helped it still doesnt post (Pc parts, mobo: Prime X670-P wifi, Ram: Kingstin fury 6400mhz, Cpu: AMD ryzen 9 7900X3D, Gpu: Rtx 4070, Power supply: corsair 750w..... Methods I tried already: Tried the stick of ram alone(both), reseated the cpu, cheked all power supply connections, reseated the gpu, reset the cmos. I have played on it before but then when i tried to power it up it didint show anything on the display but all the rgb lights in the case lit up

Did you try without the gpu, on the igpu ?

Did you try updating bios ? you have a bios flashback button

I think i mentioned it but im not sure but I have played on it on friday and worked normally then i shut the pc down flipped psu switch and took the plug out of the psu and then later powered it on and no display but all case rgb lights are on. BTW I just updated bios and still the same thing no display

Most of the time, the system will default to use the iGPU and you have to make a change in the BIOS to force it to use the GPU's PCI-E slot. If you update the BIOS it will once again be defaulting to the iGPU instead.
It's an annoying problem I've ran into before and that's what it turned out to be.

You'll have to reset the BIOS to factory default (Not update the BIOS) by clearing it, you can do that by removing the little watch (CMOS) battery for about 5 minutes and then pop it back in. During this time also remove the GPU itself and just leave it out for now.
After you pop the battery back in try to start the system and see what happens.

If you do get a display, THEN you can go into the BIOS and set it to use the GPU's PCI-E slot, save and right when it goes to reboot (When the screen goes blank) kill power (Unplug it from the wall) to the system before it tries to POST, this way the system doesn't "Undo" the change you made in the BIOS due to it trying to detect things.
Pop the GPU back in, restore power to the system and then see if it works or not.
Maybe this will work, maybe not but won't hurt to try it. I recall the one I had being really "Unfriendly" about use of a GPU instead of the iGPU and it gave me fits about it all the while.
Only way I was able to solve it period was to use a non-iGPU chip and be done with it.
