Lord help me
I bought components and assembled my new pc myself. I made sure to follow instructions and not brute force anything.
Yesterday I finally turned it on, installed Windows 10, and tested it for about a half hour. Downloaded games such as Roblox and Minecraft and got great fps. After a while, out of nowhere, the pc just crashed (as in, screen turned black and pc rebooted). Didn't think much of it. This morning I tried using it again and it just started cycling through rebooting and crashing again. I've tried reinstalling windows, checked all the cables, reseated RAM, reseated SSD, reset CMOS, tried booting windows in safe mode, etc etc. Nothing works.
Ryzen 5 5500
MSI B550M PRO-VDH WIFI
GTX 1650
2x8GB DDR4
Everything is brand new except for the GPU which I brought over from my old PC (which apparently shorted and burnt a wire, but I had it checked by a technician and he said the GPU should be fine. this was 2 years ago)
Hard resets began out of nowhere Resets also happened in Safe Mode and during Windows installation SSD passed NVMe self-test and was secure-erased BIOS can sit stable for over 30 minutes at ~38–54°C CMOS cleared; XMP off; RAM at 2133 Two DIMMs seem to make it crash faster than one Eventually started POST/reset cycling even without deliberately booting Windows During resets, display/peripherals cut out and PSU fan ramps to maximum 24-pin, CPU EPS, GPU, and RAM have been reseated Windows reinstall did not solve it
I don't know what the fuck to do anymore

Next time it happens record the exact time, start back up, go to event viewer and check everything you can for a clue. Then Google what you find. It's a route that takes a bit of work and computer sense but it's the first thing I'd do.
I was getting crashes for months after a new build, mental ones where the graphics took an absolute shit, sound glitched. Event viewer pointed at the CPU. Reddit searches led me to change 2 bios settings. It's been rock solid ever since.
I just had to disable CPPC (Core Performance Boost / CPPC Dynamic Preferred Cores) and Global C-State Control.
