You could've overloaded that single RGB out on your mobo and killed it. Try connecting only a single fan and see how it glows.

I don't recommend this, but from my experience of removing box AM4 coolers, removing it with the CPU was easier. In my case CPUs survived each time.

MSI Afterburner is pretty much classic of monitoring your hardware during gaming. 
AMD Adrenaline also works nicely to monitor CPU / GPU / RAM loads and temps as well as FPS and other stats. If you don't want to run yet another program in the background, just use Adrenaline.
 
HWiNFO is used for synthetic benchmarking as its more precise and gives a lot more details.
 
I would run 3DMark Timespy to stress test the system and see what kind of temperatures you're getting.  Might adjust fan curves if needed.

I've had same issue when I purchased 7900XTX. My PC refused to post with DP cable plugged in and monitor off. I found this reddit post that suggested to cover one of the DP cable pins. Have a read for yourself.  It fixed my issue.
 
EDIT: I have same problem, monitor backlight would come on but I got no image and no post.
 

Cool! Good to know! 
If I recall corretly, as long as the 7800x3D has a good pair of RAM sticks to go with it, that's pretty much it. Maybe undervolting will help here and there but yeah seems like that CPU is already giving it all. Thanks for your effort! 

So after spending a couple of days educating myself on how PBO and Ryzen overclocking works, then finding out my Asus B650 has a special sauce mode that allows you to overclock this puppy to 5.4Ghz, I did eventually play around with it.
 
To my disappointment and amazement, overclocking didn't produce any meaningful results. This chip is already an efficiency champion. In CPU-heavy games like BF2042 with 128 players on tight maps, this thing sips 55-60W while boosting itself accordingly up to 5Ghz. Compared to my 9900k that chugged over 200W at 5Ghz, this looks like magic.
 
I could play around more and try doing something naughty to it, but I decided not to. The performance is there and I can't ask any more from it. As for the stability, well it works.  Playing games at 4k 120FPS on max settings while having Edge open with multiple tabs in the background for youtube music, talking in Discord, and recording everything using AMD ReLive with settings cranked. With all that my system quietly cruising along with GPU staying at 70c and CPU 55c and RAM usage +/- 15GB
 
I also use RAM as a buffer memory for AMD ReLive so that I can save the last X amount of seconds/minutes of my gameplay instead of constantly recording or ruining my NAND SSD by re-writing buffered footage
 
So from whatever I did with this setup, currently it is working flawlessly.

I hope smaller forums would pop up and take the place of giant ones. Small communities that are focused on a specific subject are way more enjoyable and helpful. 
 
Reddit was just an absolute nightmare with dramas, arguments, and an overall poopstorm.

Your formatting of the text makes it unreadable, so i fixed it:
 

Success! It's alive and posted into Bios

So just received my parts for a major upgrade. Was expecting them next week, but got a surprise call from courier about delivery today... While I was at work. Very nice to finish and go on my weekend.
 
Will keep it updated when building if anyone is interested. 

3 year paste?
Ooh. I have a tube of NH-4 2016 edition I used a few month ago on some CPUs and GPUs. It seem to be even better than some of the (newer) stuff that's on there, although none of the machines are younger than the paste anyway (lol).
You will be fine. Usually the paste "goes bad" when it dries out. Or if it's total junk, then you will have separation. And those aren't really worth to be used in the first place.

But also, I will always just use NT-H2 on everything. Even if a cooler has pre-applied paste I take it off and use NT-H2. But I am more anal than most

Very true, Some stuff last's an eternity, in that case it becomes a guessing game of whether or not it was adequate paste to begin with lol
 
I've opened a few 10 year old, satchel-packaged, aliexpress included pastes recently. They were so bad that it was half chunky powder, half liquid. Wild to think that someone thought it would be appropriate to use it on electronics lol

If I pour the paste and some chunky powder comes out, yeah not staying on the CPU.

But I've been surprised by the shelf life of even the cheap stuff, never hurts to pull out the tube and give it a shot.

That's given it's a good quality compound. Have you ever opened an old cheap paste that came with Aliexpress stuff 10 years ago? That stuff can be funky

Depends on the paste, but a few years is normally fine. Just check the paste when you go to use it that it still has a consistent texture. If it looks like it has separated or dried in to a thick paste then don't use it.

Depends on the stuff, but as it's just a compound, it should be inert until placed in a situation that causes it to go through a physical/chemical transformation. I.E. heat and pressure from being used between the cpu and heatsink.

I've used stuff that's 10 years old and if it looks the same coming out of the tube as it did then, then it's good to be used now.

"Bottleneck" means your components are not balanced. Pairing a powerful GPU with a slow CPU means your GPU will get bottlenecked and won't be able to push itself to 100% because CPU is holding it back.
 
That said, 5600x should pair nicely with RTX4070

As @Somerandomtechyboi said, you can try fishing for some good deal on a used card. 6900xt / 6950xt can be found for a great price. If you can find a good deal on 3080/3090, even better.
 
As someone who used Nvidia through the 1000, 2000, and 3000 generations, switching to AMD 7900XTX after RTX3090 was a pleasant experience. Adrenaline extremely similar to Shadowplay. If you want to record gameplay, make screenshots or have instant replay to record last X seconds of your gameplay at whatever resolution/bitrate you want, its all there too.
 
On top of that it has quite powerful built in OC tool, standard for AMD CPUs and GPUs.

Have you tried changing the wallpaper?

I just built a system yesterday with 7800X3D on Asus Strix  B650E-E, 32GB 6000Mhz and it doesn't seem to have any issues (So far), but it's out of the price range. There are Asus TUF B650s with WiFi for around 230-250, x2 4.0 slots. I built a system on that board for a friend of mine a few months ago, it runs great with 32 gigs 6000Mhz in all games and some video editing. 
 
Not a fan of MSI boards in general. Somewhat clunky Bios and lack of some features.
 
Gigabyte is a solid option.
