Your computer shuts down during gaming or when accessing the internet.
I've already switched my power supply, cooler, and reset the BIOS. Whenever I play League of Legends, watch videos on YouTube, or just browse the internet, my PC shuts down completely. This issue started about a month ago. I brought it to a tech store for testing, but they said no problems were found. However, the processor turns off instantly at 100% usage, and it doesn’t require much power to reach that point. The graphics card is an Radeon RX 580X, the motherboard is an ASUS PRIME H510M-A, and the power supply is Seasonic G12 GC 650W 80+ Gold.
I suspect there might be a hardware problem despite the PSU and CPU cooler replacements. Please keep monitoring the temperatures and performance metrics of your CPU, GPU, and PSU. After turning off the computer, leave it on for a short period while running a light application or using a monitoring tool. Position a camera near your monitor to capture the visual data, then review the recorded footage to assess the system's behavior after shutdown. Let me know how it goes.
