Problem with pc

[Nemanja02]

Recently I built my first pc, everything was fine until now. Pc randomly turns off but rgb lightning stays on, except rgb on cpu cooler. And I can’t turn it on again because it’s already on. Here are my specs:

cpu: amd ryzen 7 2700x 

cooler: 2700x stock cooler

mb: gigabyte aorus x470 ultra gaming wifi rev 1.0

gpu: rtx 2080 msi x gaming trio 

psu: kolink 1050w 80+ pl

m2: samsung evo pro 512gb

ram: kingston hyperx predator 2933Mhz (2x8gb)

 

Cpu temperature is always around 40 °C,

bios is updated and everything is connected well.

Any ideas why is pc turning off?

Could be a short. Did you use standoff's on the motherboard?

No because I couldn’t place motherboard in the right place with them. Pc worked fine for 7 days.

Sounds like an electrical problem.

Id disconnect everything except this parts (cpu, cpu cooler, ram, keyboard, hdd, monitor, gpu).

You should disconnect: Peripherals, coolers, led srips, secondary HDDs, Optical drives, other PCI express cards, network. Boot into windows and keep it there to see if missbehaves.

 

Do you have and know how to use a multimeter?. It would be nice to probe what the PSU is doing while this happens.

Also is it directly connected to the wall socket or it has something in the middle, like a UPS, or extension? (Always try directly to wall to reduce failing points).
