I need some help with my custom-built PC that's been acting up lately. I put it together back in 2021, and here are the specs: Ryzen 5800x CPU, Nvidia 3080 GPU, Asus Tuf Gaming x570-pro motherboard, Corsair Vengeance LPX 32GB (2 x 16GB) DDR4 3200MHz RAM, and a Corsair RM750 power supply. For the past six months, it's been giving me random blue screens of death (BSODs) when left idle and occasionally restarts when powered on. It's also freezing after a couple of hours when the screensaver kicks in.
I thought it was caused by some software I installed, so I cleaned up my system and even ran Bluescreenview for some diagnostics. Unfortunately, that didn't solve the issue. I decided to do a clean Windows install, but that didn't go smoothly either; it kept freezing during setup. I suspect that my RAM, NVME, or PSU might be faulty, so I replaced all three components, but the problem persists. Now I'm considering getting a new CPU, motherboard, and RAM combo, but I want to see if there's anything else I might be missing before I invest more money. Any advice?

You might want to run some diagnostics on your NVMe too, as they can fail without obvious signs. Also, remember that not all RAM is compatible. It could be a good call to reset your BIOS settings just to rule out any unknown configurations that might have changed. Keep us posted if you try these!
I had a similar issue with my system, and it turned out to be a bad CPU. It was surprising because it passed stress tests, but under lighter loads, it would crash. If you've already RMA'd your NVMe and tried different RAM sticks, then I’d recommend checking your CPU too.
From my experience, fluctuating power from PSUs can lead to system instability, especially with a demanding GPU like the RTX 3080. Double-check your PSU connections and consider trying a different power supply. Also, look into whether your NVMe drive needs any firmware updates.
It sounds like your RAM could be the culprit. I suggest starting there since it's often the most common issue with random freezes and BSODs. Make sure to try each stick separately and test them out. If you're still having issues, then we might need to look at other components like the motherboard or CPU.
If you’re dealing with random crashes while idle, you might want to check your BIOS settings. Some power-saving features, like C-States on Ryzen, can cause issues. Try disabling those and ensuring your BIOS is up to date. Additionally, make sure that the RAM isn’t overly clocked with XMP settings, as that can cause instability too.
