Question PC often hard-freezing shortly after reboot ?

[fabbo]

I have a PC, self-built from components, that hard-freezes, seemingly randomly. Sometimes it reboots spontaneously, sometimes it doesn't. Sometimes the mouse pointer works for a few seconds while the rest is unresponsive, then everything freezes. Some other times everything freezes right away.
I tried Linux with console on serial: no messages are printed on the serial when the freeze occurs (I was hoping in some kernel panic message).

The strange thing is that it seems to occur mostly within a few hours after a reboot. If the PC survives the first few hours, it can go on for days and days, and even be suspended and resumed, until the next kernel upgrade that forces a full reboot.
I tried other OSes, namely the NomadBSD FreeBSD live distribution, and the problem exists there as well.

Any suggestions?

full system spec? include brand and model of the psu

check cpu/gpu temp? ssd health?

 

[fabbo]

psu: Cooler Master MasterWatt Lite 500
cpu: AMD Ryzen 7 1700
MB: Gigabyte GA-AB350-GAMING
memory: Crucial - DDR4 16 GB 2666 MHz
ssd: Transcend MTS800 256 GB (M.2 connection)
gpu: ASUS EX-RX570-O4G (Radeon RX 570)

Huge yikes on the very junky PSU. Without anything else obvious, since a that PSU shouldn't be running an RX 570 under any circumstances, an upgrade to a competent PSU would be my first step.

Any suggestions about good PSUs?

Any suggestions about good PSUs?

Depends on location. There's a curated PSU list in the forums (slightly out of date, but it works for now). Anything Tier A or Tier B would likely be fine with this build. Corsair CX PSUs will usually be the least expensive PSUs worth buying, but there's variance from market-to-market.

I have to bump this thread, because I upgraded the PSU to a Seasonic G12 GC 650W, which has higher power than the previous one, and is good quality according to https://cultists.network/140/psu-tier-list/ , but the symptoms persist.

The only suspect thing is an oops that occurs every time Linux is booted:
