Hello guys, i've been encountering an issue ever since i've built my new PC and it's driving me insane now.
My computer seems to be crashing when on low load such as browsing the web, opening the browser, or something similar, not while gaming or stress test or anything of that sort which is weird.
Crashing, as in monitor loses signal, keyboard loses signal, mouse loses signal but the CPU and fans seem to be still running (Led light is on on the case as well) Only way to get out of the situation is to force reboot with the case button.
I have no idea what is causing this, i've tried changing the power plans (now on ryzen balanced) and setting different cpu minimum state limits(0-100%), i've tried giving generous voltage to the cpu(offset is at +102 now, around 1.28v says on the cpu Z), under clocking RAM from 3200 to 3000 but nothing seems to help. This problem occurs randomly maybe once in a week or so. I have the latest drivers installed, the latest windows, latest bios, latest chipset drivers.
I'm out of ideas, if anyone more knowledgeable knows what might be the cause of this i'd be really thankful.

My System:
Mobo: B450m ds3h
Cpu: Ryzen 1600AF
Ram: Corsair Vengeance LPX 16GB 3200mhz (running at 3000 because anything above that is unstable for some reason??? on 3200 crashes withing 10 min of boot, on 3133 gives out some errors but is stableish, so i keep it at 3000)
Cooler: Really good random cooler with 6 heat pipes, Cpu max temperature is 50 undr load, i have additional active cooling on VRMs
GPU: RX 570 4GB Overclocked (1400 on Core 2000 Vram and under volted -50 and additional 30% power limit, Msi afterburner)
Power Supply: 600watt futureman, (450-500 watt-ish on the 12v rail, has all the proper connectors to juice the system, 8 pin cpu, 8 pin gpu)
Storage: Single ADATA sata SSD
Case: Random old case
OS: Windows 10 Pro

Thanks in advance.

Power supply seems to be alright. With the previous system i had, a more power hungry CPU + overclocked and the same GPU with the same overcklock and i don't remember having a similar problem.
This new system uses less power and CPU isn't even OC'ed, plus the crash only happens when not under load, with stress tests and gaming it hasn't happened yet. Another thing is that 480w should be sufficient for a ryzen 1600af with rx 570. so that's why i'm thinking the PSU is fine.

As for ram sticks, they do seem kind of defective as i can't get them running at 3200(rated speed) even with high timings and more voltage.
I tested the RAM yesterday with memtest overnight at 3000mhz and it shows no errors. At 3133 and 3200 it shows errors.

Temperatures are perfect on everything, overkill cooler on CPU max 50c on stress test, GPU doesn't go above 72c when playing games (side panel of the case is open) and i have a cooler on VRM of the motherboard. (50-60c on chipset and vrm in stress)

Only thing i noticed that caused the issue to become more severe was when i put the minimum processor state to 100% in windows power management with stock voltages on the cpu. Increasing the voltage hasn't helped solved it but it became less severe and less often, CPU-Z says cpu is on 1.27-1.28 voltage while running at max boost speed 3700mhz.
Setting the minimum processor state to 5% has the same effect as increasing the voltage, it happens less often but still happens. I'm pretty confused.
