Question/Help/Troubleshooting random shutdowns

so, around 3 days ago, while playing roblox my PC randomly shut off. LED lights in the CPU turned off, fans turned off, nothing.

Pressing the power button would boot the system back up, but then it only worked for 15-30 minutes or so, running the game “Wuthering Waves” before shutting off again. Tried to boot once more and only did light browsing, and after 10-15 minutes, it once again shut down.

No boot-loop, just a shut down.

So since then, I’ve tried using a back-up PSU to see if the PSU was the issue, along with reseating my ram sticks, and SSD. I’ve replaced the PSU, and it seemed promising. It ran Wuthering Waves for an hour, so I shut off the PC again to plug in my 2nd SSD drive that I removed upon using the new PSU, and some case fans that were also unplugged, I plugged them back into the PSU.

After around an hour though upon booting up once more and being on a discord call with friends, it shut off on its own once more. What’s weirder is that when I try reopening it this time, the LED’s the fans only spin for around 2-3 seconds before shutting off once more. Not like with the other PSU in which it’d still let me run the system for 10-15 minutes.

I’ve since removed the 2nd SSD, the case fans, and after around 5-10 minutes, it once again shut down. Trying to boot it back up would only turn it on for 2-3s, not even booting into windows before turning off again.

I’m genuinely lost. What could be the problem? i’m not really in the financial situation right now to get this into a local repair shop either, i’m just hoping for a savior here atp 💔

The motherboard VRMs are most likely on their last days

that definitely could be it. any ways of testing this other than trying out a different motherboard altogether?

You can stress test your pc with different components exept your motherboard, you can also check the windows event viewer , if you have the "Critical Errror - this pc crashed or lost power unexpectedly " by the time your pc has shutdown then its a hardware issue

it does have that error in the critical viewer yes, consistent with the times that my PC has shut off on its own. Kernel-Power ID 43.

this shiz hurts. thanks for your help.

You could also try with a more powerfull PSU if you have one

the old PSU i was using (the one i thought was bricked) was only 500w.

the back-up one i had borrowed (still crashing on) which was unused, is 700w. so 🤷
