I recently built a new PC with the following components: a Ryzen 7500F processor, a Seasonic G12 GM 750W Gold power supply, a Gigabyte B650 Eagle motherboard, and an RX 7600 Sapphire Pulse graphics card, along with 16GB of Kingston Fury DDR5 RAM. I ran an hour-long OCCT test without any shutdowns or errors, and my max CPU temperature was 76°C, GPU hot spot was 85°C, and RAM temperature was 36°C. However, while playing Marvel's Spider-Man (2018), my PC suddenly shut off completely after 1-2 hours—no lights, no fans spinning, nothing. I've ensured everything is at stock settings with XMP enabled in the BIOS, updated to the latest version (F36), and also updated the GPU drivers. I'm really confused about what could be causing this issue.

Unexpected shutdowns like this often point to thermal issues or a power supply safety feature kicking in. It’s possible that the sudden spikes in FPS when playing in certain areas are causing voltage spikes that trip the PSU. If you're getting high FPS, maybe try capping it around 120-130 FPS in the driver settings and see if that helps.
Did you notice any screen flickering before it shut down? You might want to check the Windows Event Viewer for error logs. Just type 'event viewer' in the start menu, go to Windows Logs > System, and look for the timestamps around when it happened. That could give you some clues.
