What causes my PC to shut down unexpectedly?
Previously, I could play games on my PC with ultra settings without any heat or lag. Then the screen behavior changed unexpectedly and the system shut down. I checked the CPU using a ZCUPS monitor but don’t understand what’s happening. Here’s a video showing the CPU activity during gameplay. I’ve tested three different games now, and the issue continues. What should I do to fix it, especially since this has been problem-free for over a year? The hardware specs are: BIOS A320M motherboard, AMD Athlon 3000G 4.5GHz CPU, ASUS GTX1650 4GB GPU, Kingston Fury Beast 16GB DDR4 RAM, and an EVGA 600 PSU.
Model or part number? The item is a model or has a specific part number. Was it purchased new, or did it come used or refurbished? How recent is the device?
I built it myself roughly a year or two ago using new components. The PSU is an Evga 600 BQ that I purchased new about a year or two ago.
your psu could be getting older.
you need to clarify what unusual behavior you're experiencing, such as funny events on the display or boot issues.
The image began to lag and freeze, then exited full screen, copied that window into around 40 copies, locked the mouse, and finally shut down completely. No error message or blue screen appeared. Restarted immediately after pressing the power button. Now it shuts down after roughly 5 to 10 minutes during games. Passed a stress test on the CPU. Reformatted and installed fresh windows containing only drivers, Steam, and one game. Still behaves the same while gaming.
EDIT
: Can someone explain what the video is saying?
Your video mentions your CPU running at 50 degrees during games, while your graphics card uses 95% of its capacity. The GPU shows 80 degrees of heat, though most people say it's fine. However, I don't fully trust NVIDIA—my GPU could be overheating due to the high temperatures. A 600-watt PSU seems sufficient for your setup. I recommend lowering your gaming graphics settings and setting a lower FPS cap to see if performance improves. It's hot outside.
