I'm having an issue where my PC completely shuts off while I'm gaming, but it runs perfectly during long benchmarking sessions. When I stress test it for hours, it holds up fine, no overheating or strange power issues. However, during gameplay, it shuts down after 20 minutes to 2 hours randomly. There's no crash log since it's a hard power off. I've checked power draw and temps, and everything looks normal. Even used a friend's power meter and the load is well below the PSU's capacity. I've noticed this happens across different games, not just Unreal Engine 5. I'm puzzled about what could be causing this, especially since benchmarking sometimes uses more power. Any ideas what might be going on?

I had a similar problem before, and it turned out to be a faulty RAM stick. I used Memtest to narrow it down to which stick was causing the issue. I suggest you do the same as part of your troubleshooting; it might just solve the problem!
It sounds like your PC is shutting down completely and isn't experiencing a crash or freeze. That often points to issues with the power supply unit (PSU) or potentially the motherboard. It might also be the PSU cables or maybe even the power strip you're using. I'd recommend trying to plug your rig into a different outlet and see if that helps.
I'm running Memtest now. Thanks for the suggestion! I'll let you know what I find.
