I'm having a frustrating issue where my PC crashes unexpectedly while I'm gaming. There's no blue screen or error message—just a black screen and a complete shutdown. To get it back on, I have to manually power it up again. I upgraded my CPU, motherboard, and RAM recently, which helped for a bit, but the crashes have started happening again, albeit less frequently.
Earlier, I thought my CPU was the problem because I got some CPU-related errors, but after the upgrade, everything seemed better until recently. Also, I've been seeing some "Realtek Gaming 2.5GbE Family Controller has a Hardware IO error" messages in the event viewer, but I think that's a separate issue. I have very limited knowledge about PC hardware and software, so any guidance would be greatly appreciated! My build can be checked [here](https://pcpartpicker.com/list/G9VPGJ).

It sounds like a power supply issue to me. If your PC is shutting down unexpectedly, that could be due to the power supply not providing enough juice, especially when under load during gaming. I’d suggest looking into upgrading your PSU as your first step.
You might also want to check for overheating. PCs can shut down automatically to protect themselves from thermal damage. Monitoring your temps while gaming could help pinpoint if that's an issue. If everything looks fine, it might be best to dig deeper on other hardware.
Also, make sure to grab the dump files from your system. They can provide valuable clues about what might be causing the crashes. You can find these in C:WindowsMinidump. If you can upload them, it’d help others assist you better!
