OK, so here's what I currently have:

Ryzen 5 2600
RTX 2060
ASRock B450M
512G SSD
32G 3600 RAM
500wPSU

I wanted to upgrade a bit so I bought:

Ryzen 7 5800x3d
Radeon 6700xt
Peerless assasin 210 cooler
Corsair 750w PSU

So here's my problem. After swapping in all the new stuff, my PC just started power cycling. I put in the old CPU and it just gave me a black screen. Putting the HDMI in the mobo gave a gray screen. So I tried old cpu new gpu. Nothing. Gray screen on both. I downloaded the latest non beta bios from ASrocks site and put it on my mobo and tried the new cpu again. It gave me a screen where it detected it, but went black after I hit Y. I have no idea what's going on and would sure appreciate y'alls help.

Your motherboard video output isn't going to show anything with either of those CPU.

Put the system back in its original configuration. Reset CMOS and see if you can get a boot. If so, double check your BIOS and it's suitability to the new CPU, also check on the compatibility list to make sure your motherboard supports it. If so, update the BIOS, power down and swap your CPU in and verify it boots. If so, then go back into BIOS and reset your 'XMP' profile and such. Then, if it is working correctly, put the new graphics card in.

OP says it is an ASRock B450M in the first post. There are quite a few variations of that same model number such as Pro 4, Steel Legend, HDV, /ac....I imagine that given the one link for a manual they all must be pretty much the same aside from some color tape and heat sinks.

@PEnns that motherboard looks suspiciously proprietary. (especially since you can see the Dell logo)

That's about where I'm at now. I reset the cmos and I have my old cpu and gpu in now. It starts up and runs fine. I downloaded BIOS version 3.10 released on 11/2/22 for the b450m/ac. I'm thinking it should be compatible, but I don't know how to check if it is or not.

Sorry, my mistake, for a second I thought the OP was asking what's a motherboard.!

OK, I'm back. Had to deal with 2 weeks of Rona. Haven't touched the PC since then. I ended up putting the old CPU and GPU back in with the new PSU. Everything worked fine so I didn't touch it. It looks like I do have a B450M/ac, so like @punkncat said, my MOBO isn't compatible. Unless y'all see something different, I'm gonna have to get a B550. I don't know how to post pics on here, but I have one and it does say B450M/ac in-between the PCIe slots.

Jesus this is getting old. I'm just not made for this I guess. I flashed the bios and enabled xmp to set my ram to 3600. Saved and exited. CPU reboots and goes into bios. Pulled my flash drive out and reset. Went straight to bios. UEFI hard disk it set as 1st boot priority but it won't boot to windows.

OK, I figured out how to enable legacy + UEFI and windows came up. Downloaded DDU and ran it, swapped in the new GPU and got nada. Nothing. Just gray screen. No boot sequence screen, no bios screen, nothing.

With graphics card plugged in, do you get bios picture at least? If you do then that indicates the card is working and think your main problem is using an existing Windows install.

Windows was installed under legacy + Uefi environment from last motherboard wasn't it? Changing motherboard when Uefi only is usually the default option until changed would cause no display when Windows tries to load. It is recommended to reinstall Windows after a motherboard change anyway, so backing up your stuff should be on the to-do list before you proceed further. When you're ready to install Windows put bios back to Uefi only.

I have no display at all with the new GPU. No bios, no boot, no nothing. If I put the old GPU back in everything works. It's just ugly since all the drivers are gone.

Well that has nothing to do with Windows or drivers then, you should be getting post/bios display which is before Windows/ drivers load so it's not software. Something else is wrong. Recheck pcie power cables.

Was card bought new or used? Can you test it elsewhere?

I've used both connectors on the piggyback pcie cables on the old GPU and both work fine. The new GPU uses both, old uses one.

I bought it new from Newegg and don't have anywhere else to test it. I'm starting to think it may be bad.

I just tried the "boot to safe mode" DDU method. Nothing.

Here's how it goes:
Turn PC on
Screen goes black a second
Receiver goes to "no signal" screen a few seconds
Screen turns gray for eternity
Swap GPU back to old one
Everything works fine

Not sure if it matters, but I'm using a 2.1 HDMI cable to a 65" TCL 65r625 TV.

You mean a single cable with two 6+2 ends? Rtx 2060 uses 8pin, 6700XT uses 6+2pin and 6pin yeah?

That way should work but try two separate pcie cables, you should have a couple at least. Only use cables Corsair came with, don't use cables from different power supplies if you have any. Not because two separate cables would be the fix, just having you go through this process might have you catch something before assessing rma. Double check pcie ends are properly connecting to 6700XT.

Gimme a few minutes and I'll get the cables swapped.

Nothing. 2 seperate cables and still gray screen. I did have to reuse the piggyback cable. The new PSU only came with one single PCIe and the piggyback. There is another cable labeled CPU that's the same shape, but it has pins in all 8 whereas the PCIe cables have 1 slot open.
