I'm having a frustrating issue where my computer unexpectedly restarts without any warning, and it seems to happen regardless of whether I'm using it or not. My setup includes an MSI Z790-P motherboard, Intel i5-12600KF CPU, 32 GB of DDR5 RAM, an RTX 3070 GPU, and both an NVMe SSD and a HDD for storage. Most of these components are new since I had to replace my motherboard recently due to failure.
Interestingly, these restarts started after replacing an old SSD with a new one, although I'm not sure that's the cause since it happens with both my SSD and HDD. I've tried numerous troubleshooting steps: removing peripherals, resetting BIOS, running memory tests, and checking event logs, but nothing seems to help. The restarts can happen just a few seconds after booting or sometimes after hours of use. I'd appreciate any insights or tips from the community on how to diagnose or fix this problem!

Have you checked your RAM again? Sometimes just reseating them or testing with different combinations can help. You mentioned testing individual sticks, but you might want to try a RAM stick in different slots as well. A slot could be faulty.
It sounds like you’re dealing with a tough issue. Have you thought about potential thermal issues? You mentioned some high temps during testing. It might be worth reapplying thermal paste on your CPU and making sure everything's well-cooled and seated properly.
Hey! It sounds like you've done a lot of the troubleshooting already, which is great. Since you're not getting BSODs or dump files, it could indicate a power issue. Have you tried swapping out your power supply? Sometimes PSUs can fail in ways that cause intermittent restarts without throwing traditional errors. If you can, try using your old PSU to see if that resolves the problem.
It’s interesting that the restarts happen during light usage. This could indicate a problem with power delivery to the components. I’d suggest checking the PSU cables and making sure they’re secure. If you have any old PSU laying around, it might be worth a shot to try swapping it in temporarily to see if it makes a difference.
Definitely check the motherboard BIOS updates! You mentioned you’ve updated it, which is good. Just in case, make sure you also check for any available updates for your GPU. It’s not just drivers; the actual BIOS on the GPU can also cause weird instability issues if it's outdated.
