Question My friend's pc

[caveybluesclues]

My friend is building a pc, and I'm guiding him through discord. I know this a very bad idea, but I thought it could be very fun. Turns out it was miserable because we thought we were prepared buying used parts, but we missed out on a lot of stuff and some of them we didn't read properly. And also the case came broken because shipping.

Parts chosen:
5600x (USED ,Didn't list as a broken product ebay)
Thermaltake toughpower gf1 850 gold (USED, came with cables also wasn't listed as broken ebay)
MSI b550 pro vdh wifi (Used off of amazon)
G skill ripjaws 3600 2x8gb (new amazon)
Merc 319 6900 xt (USED Ebay wasn't listed as broken)
WD black Sn850 (used ebay also ready carefully)

Alright we built the pc and was able to go to the bios. Everything perfectly fine in the bios no shut offs it pristine, but after exiting the bios it starts boot looping. The farthest we got was the windows setup through usb then it starts boot looping. We thought it was the bios version, so we updated it and we got farther. We go to the windows first time screen where you choose your language and it asks if you want office program, then it turns black and starts boot looping again. I really don't know what to do. We tried resetting the cmos battery by removing and putting it back, trying one stick of ram at a time for faulty ram, we updated bios. I've looked through 10s of posts on the internet, but didn't find a working solution. Is the motherboard faulty? Cpu? RAm? PSu? Gpu? SSD? Help me out please.

So, the only thing that maybe reliable in your slightly cooked but not dead yet (ebay), system is your RAM.
The only way to troubleshoot such disaster is to test, at your own risk, each and every part in a known good PC.
A fried part may affect your good computer, so beware. All E-Bay electronics are slightly fried, but not dead.
Also the Ryzen 5 5600x CPU has a ram speed limit of 3200mhz, you can force it to 3600mhz but the gain of performance vs. instability is too little to mention. 400mhz is 11%, giving you only a 1.1% overall gain in system perfomance, you are better off with RAM of better CL/CAS timings. If you had a 50% or higher gain from OC via XMP I'd be all for it. Also, in order to troubleshoot we would need MB beeps, codes, anything you can see before post. If you did get to running Windows, maybe a variety of factors, because Windows installs the wrong GPU drivers, but also could be faulty PSU, or a fault in the SSD. Too many factors, too little info. You said nothing of the CPU cooling system.

I did not put the ram in any xmp profile for testing purposes, so the ram is at like 2100 mhz but still boot looping. I don't anything about how to get the motherboard to beep. I also don't have any spare parts to rule out each part. Also my cpu cooler is the stock wraith cooler that comes with the 5600x. Thermal paste the size of a fat grain of rice and the cpu fan is spinning, so I don't think there's any problem with the cooler. I just want to at least get to the windows desktop, but I'm very confused about what's causing it to shut off once I was that far.

That maybe too little a thermal paste, if that size, I'd make 5 dots pattern.
But you can get into bios yes ? Leave it idle in bios in the Fan/Temps screen (Advanced).
If CPU idles above 45C you have a problem.
Things that cause reboots & crashes: faulty PSU, faulty GPU, faulty CPU, high Temps., damaged MB.
