[Moderator edit to break up one solid paragraph of text.]

Can someone help me figure out the problem I am scared and can't get a nap.

Basically in the morning my PC was running fine i shutdown my pc and turned off PSU, after 2 hour next time i turned on PSU and pressed power button PC turned on for 1 sec and turned off but I saw RAM rgb still on so i turned off PSU switch and rgb was still on so i remove the plug entirely and soon rgb went off.

My english is kinda bad.

After that i put the plug back in and turn on PSU switch i saw small spark on the switch but same happened i again and repeated the same thing this time PSU made like a buzzing noise again turned off PSU and removed plug after that.

Again i plug in the cord and switch on PSU this time when i switch on my PSU my room breaker went out. My country power can go out randomly, so when i was trying to pull all my courage to try it again power went out and i went to sleep.

When i woke up i didn't try turning on PC but directly pulled out RAM and put it back in as i saw somebody say it could solve the issue. Again after reinstalling RAM When i plug my cord , turn on PSU and power button my PC started working fine since then.

i dunno what caused the problem here i dunno if it was PSU, RAM or if the whole electricity was low power at the time. Also i am so scared to even touch PSU switch, but at the same time i wanna turn off PSU switch thinking when i am sleeping power might go out and come back damaging my PC.

PSU that i use is NZXT c850 80 plus gold.

My spec are :

Motherboard: Msi z690 a ddr4
CPU: Intel i7-12700k
GPU: 3070ti msi Suprim x
RAM : 32 gb gskill 4000mhz
OS: windows 11
PSU : NZXT c850 80 plus fully modular
SSD: samsung evo 980 pro 1 TB

PSU and whole system is like 1 and a half year old, i purchased in local retail store where i bought everything else from. It was sealed original / new. I don't do heavy gaming often as it's super hot in my country and GPU temps goes around 70 so just occasionally every now and then. SSD got like 400gb free.

Update your post to include full system hardware specs and OS information.

How old is the PSU? Where purchased? Original to build, new, used, refurbished? Heavy gaming use?

Disk drive(s): make, model, capacity, how full?

Have you reset the motherboard BIOS?

When there's a power outage very often, it's a good idea to use a UPS.

I am scared to touch bios stuff because power might go out. i haven't had any issue from yesterday so i have no idea what exactly happened at the time
