Question PC turns on but after several hours it turned off ?

[Nightcurse]

Just need some advice, I encountered a weird problem yesterday my pc turns on then after several hours it turned off. However the system fan, cpu fan, gpu fan, psu fan are all spinning even the light on rams and chipset, but mouse and keyboard don't have power. I tried opening again and it power up, was able to log in then after minute it shut down again with working fans and lights but no mouse and keyboard.

How can I fix this? I tried my cpu, gpu and ram on other pc and it is working but i can't try another psu and motherboard since i don't have spares.

Spec:
B550 tomhawk
ryzen 5 3600
palit gtx 1650super
gskill trident 3200
aerocoll rave 550w bronze 80+
