I've been having some frustrating issues with my PC lately—it shuts off unexpectedly when I'm putting any load on the CPU. Just today, I tried running a game like War Thunder, and it only lasted a minute before the screen went black and the system powered down. Now, it won't boot up again until I unplug it from the wall. This started about a week ago, and I'm starting to think that it might be a motherboard problem. I've tried a few things already, like applying new thermal paste on the CPU, testing different power supply units, reseating RAM sticks, and updating the BIOS, which only slightly changed the behavior. My stress tests cause crashes when the CPU is under load, but the GPU tests out okay. The event viewer is full of critical kernel-power errors. Here are my specs: R7 7800X3D, RX 7900XT, AORUS B650 Elite AX, running Windows 11, with both an 850W be quiet PSU and a 750W EVGA PSU. I'm looking for some advice before I potentially spend money on a new motherboard—any thoughts?

This issue really seems to point towards either the CPU or the motherboard being the culprit. From what you've described, the motherboard is likely where the problem lies. If you can, try testing the CPU in a different setup to see if it behaves the same way under stress—this could help pinpoint the problem. Alternatively, you could swap in a different CPU into your current motherboard if that's an option too.
I totally get the frustration of this kind of issue. If you're not able to test your components in another rig, it might be best to just go ahead and replace the motherboard. It could save you time and hassle in the long run. Just make sure to back up your data before you make any changes!
