[SOLVED] New computer won't boot into BIOS

[TheUsergamer]

Specs:

Mobo: MSI X570 TOMAHAWK
CPU: AMD Ryzen 7 5900x
Ram: 32GB 4400 Mhz Corsair Ram
SDD: 2 1TB Samsung 980 nvme's, 1TB Samsung 980 SSD
GPU: NVIDIA EVGA GeForce RTX 3080

It is a new computer with brand new drives. The only thing I did to it was that I flashed the motherboard with the latest version on MSI's website for the TOMAHAWK, renamed as MSI.ROM beforehand and now the computer won't even boot into BIOS. The only thing I can tell that could be possibly wrong is that when it is on, the EZ debug light is on VGA meaning something is wrong with the GPU, but I tried to load it with unplugging everything from and out of the GPU and it still wouldn't boot in. I also tried reseating the ram, but that didn't help either.
I can't get a signal from my keyboard or monitor, however when disconnected in the state my computer is in, the monitor reacts to being disconnected and reconnect, just no signs of showing a pictureon the screen, just being black, this is both being connected to the motherboard and GPU. The fans work and the rbg RAM shines.

Would it boot into BIOS before you flashed it?

Connect monitor only to GPU as the motherboard connections function only with an APU, not a Ryzen CPU.

Stopping at VGA as it is I believe means it's successfully POST'ing through CPU and memory but the GPU is failing so it could be defective. Try it in another system or try another GPU in that one to eliminate it. Also try it in the other PCIe x 16 slot.

I wouldn't know, but I assume not since the motherboard and the cpu are some different generations, hence the need to flash it and I didn't check beforehand.

I will connect only through the GPU from now on.

I did try it without the GPU, but I had the exact same problem as before with the EZ debug light shining on VGA

That's the expected response without a GPU, and makes it suspect.

If you can try it in another system would be best to eliminate it, but the motherboard socket could also be defective so that's why to try it in the other PCIe x16 slot.

Where did you source your GPU?

And double check you've solidly inserted the GPU supplemental power connections, at both GPU and PSU ends.

I got the GPU directly from EVGA.

I triple checked it should be plugged in correctly.

I will try it in the other PCle x16 slot tomorrow, and if it still doesn't work, I don't have an other system to try it on.

I'll also check the connections tomorrow as well, thank you.

THAT has got to be a relief since you have a warranty to fall back on if it proves to be the defective part.

Okay, to make sure, my GPU has two separate 8 pin connectors. Do I link them on the PCI-E side or the molex side on the PSU?

Not sure what you mean. You connect a cable from PSU to the connectors on the GPU. Some cables have two connectors on the GPU end. It's best to not use the 2nd connector but run two cables from the PSU to the GPU, so there will be (usually) two extra connectors dangling at the GPU end. That PSU should have ample cables for this.

Read the instructions with the PSU to make sure you're not reversing the cable. Do not force connectors, once aligned they should slip together until the pins engage, only then push firmly until it clicks in.

Okay, the GPU seems to work perfectly fine on the other PCI-E lane, so I need to return the Motherboard in for repair or is there someway I can fix it?

The problem lies in the first PCI-E lane since the bottom functions perfectly with the GPU. are their any clear instructions on how to fit the first PCI-E lane without the CMOS battery and jumper which I have already done?

If this is a brand new motherboard I would not attempt fixing it as that may result in voiding warranty. Return to seller for exchange, if you can, or contact the manufacturer tech support to see about them repairing or replacing it.

Also, be sure to check your CPU first: remove it and check for bent pins in particular. Since the first PCIe socket is tied directly to the CPU bent pins at the CPU could be the cause of your problems. The lower PCie socket is tied directly to the chipset so that's why it can still work.
