Hello, the problem began a few days back while I was playing Doom: The Dark Ages, Helldivers 2 and Space Marine 2. My PC would restart suddenly without any BSOD—just a quick reboot. It often happens after a long gaming session, sometimes just a few minutes on the desktop. There’s no Event Viewer log except for the PC shutting down unexpectedly. I’ve tried adjusting the undervolting settings, but that didn’t resolve it. I also updated my BIOS, yet the issue continued. When I ran OCCT, Cinebench and DOOM together for 20 minutes, the reboot happened consistently. So I went back to driver version 566.36. After that, I tested OCCT (CPU, RAM and GPU), Cinebench and DOOM simultaneously for an hour, and everything seemed stable—I believed the problem was fixed. But later that day, the PC restarted again when I opened Task Manager (though I’m not sure it’s connected). After that reboot, it restarted within 10 seconds after logging in. It also restarted after Beat Saber (via PCVR) crashed due to a VC_Redist error (I reinstalled the driver). I opened Task Manager and was about to end the task when the PC restarted suddenly. I replaced my PSU recently because it had failed about a week prior. But I don’t think the PSU is the cause, since I successfully ran all those tests before the reboots. CPU temperatures stayed below 80°C. I also want to note that I have 32GB of RAM—2x8GB HyperX Fury and 2x8GB Kingston Fury. As far as I understand, they’re essentially the same product, just rebranded. I’ve been using the Kingston modules since March and haven’t had any reboots yet. The only thing I haven’t tried is reinstalling Windows. At the moment, after two hours of Cinebench + DOOM + OCCT, everything is functioning properly. I’m uncertain what’s behind the issue—could it be the motherboard or something related to Windows?

Did you replace every single cable? PSU cables (the internal ones, not the wall connection) aren’t standardized, so swapping them between power supplies isn’t possible unless you’re sure the manufacturer matches their pin configuration. Random reboots point to power issues. Would you mind sharing the last 1–2 days from Event Viewer? Please upload the .evtx file for analysis.
Brother, I know you're dealing with the same problem they're facing. It was the PSU. Just because your components pass a stress test and don't restart doesn't guarantee the PSU is reliable—makes no sense, but I tried to help. The PSU can fail at certain voltages, like during specific game moments or even without any load. I was really scrambling to find a fix, trying to solve something no one else had encountered. I think back to my original post about this issue—it might not be the PSU, but it definitely sounds like it.
